Privilege escalation in the Windows Telephony Service (TapiSrv) allows an authenticated local attacker with low-privilege access to gain SYSTEM-level privileges by exploiting a race condition in how the service handles concurrent access to shared resources. Affected products span Windows 10 (multiple feature releases), Windows 11, and Windows Server 2012 through 2025, representing a broad swath of the Microsoft ecosystem. No public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but a vendor patch is available via the Microsoft Security Response Center.
Remote code execution in Ozols Grupa OZOLS on Windows (all versions before 1.1.1233) stems from an abandoned automatic-update domain that the OzolsSQL client still trusts. Because updates are pulled over cleartext with no integrity or signature check, anyone who re-registers the lapsed domain (or performs a network MITM) can serve a malicious serv_update.vbs that the <db>_update SQL Server Agent job executes as ActiveScripting, yielding full host compromise. The flaw carries a CVSS 4.0 base of 10.0; it was reported by ENISA (EUVD-2026-62704) with a vendor patch available, and no public exploit or CISA KEV listing is identified at time of analysis.
Broken authorization in Flow-Like's Azure presign endpoint allows authenticated app members holding only `ExecuteEvents` permission to obtain Azure Blob Storage SAS tokens with read, write, delete, and list (`sp=rwdl`) access to application content - permissions they explicitly should not possess. Only self-hosted Flow-Like deployments prior to version 1.0.4 using Azure Blob Storage are affected; the vendor's hosted services (Flow-Like Studio and the hosted Web App, both AWS-backed) are explicitly excluded. No public exploit has been identified and the vulnerability is not listed in CISA KEV, but the flaw is mechanically straightforward to abuse given that the credential overprovision is a direct API response to a single authenticated request.
Stored cross-site scripting escalating to arbitrary OS command execution affects the SiYuan personal knowledge-management application through version 3.7.3. Because the '((' block-reference autocomplete popup renders a candidate block's name, alias, and memo fields into HTML without escaping, an attacker who controls those metadata fields can plant a self-firing payload that runs the moment a victim types '((' and surfaces the crafted block; SiYuan's Electron shell runs with nodeIntegration enabled, contextIsolation disabled, and no CSP, so the injected script reaches require('child_process') and executes host commands. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the XSS-to-RCE chain is fully described by the VulnCheck advisory and vendor GHSA.
Pre-account takeover in 4gaBoards before 3.3.8 allows a remote unauthenticated attacker to seize a victim's account before the victim ever logs in, by exploiting the SSO identity-linking logic. An attacker registers an unverified local account using the victim's email address; when the victim subsequently logs in via Google, GitHub, Microsoft, or OIDC SSO, the server locates the attacker's pre-registered account by email and links the verified SSO identity to it without confirming local account ownership, granting the attacker persistent password access to the now-SSO-linked account and all associated projects and data. No public exploit code or CISA KEV listing has been identified at time of analysis; the CVSS 8.8 score reflects the low attack complexity and high impact once victim interaction occurs.
Sandbox escape via link following in Google Chrome's CredentialProvider component on Windows allows a local attacker to execute arbitrary code outside the browser's security sandbox, affecting all Chrome versions prior to 151.0.7922.169. The vulnerability stems from improper symbolic link or junction resolution (CWE-59) in the CredentialProvider, a Windows-specific subsystem handling credential operations, enabling a local attacker to redirect file access operations to attacker-controlled paths. No public exploit code has been identified and CISA's SSVC assessment confirms no known exploitation; however, the full CIA triad impact and sandbox escape potential make this a meaningful local privilege boundary violation.
Full takeover of Oracle Identity Manager Connector versions 12.2.1.4.0 and 14.1.2.1.0 is achievable by a high-privileged, remote attacker exploiting the Microsoft Active Directory component via LDAP, with confirmed scope change impacting additional Oracle Fusion Middleware products. The vendor-assessed outcome is complete loss of confidentiality, integrity, and availability. No public exploit code or CISA KEV listing has been identified at time of analysis, placing this in the category of serious but not actively weaponized vulnerabilities pending patch application.
TLS certificate verification is globally disabled in fbeta-GmbH's ePA3-Service-OpenSource prior to version 1.3.0, exposing all traffic between the integration service and Germany's electronic patient record system and Konnektor devices to interception by network-positioned attackers. Both the primary TLS layer - via hardcoded `verify=False` in Python requests sessions across two independent modules - and the VAU protocol's application-layer certificate validation are broken simultaneously, eliminating all cryptographic trust anchors with no defense-in-depth fallback. On the Konnektor communication path, an impersonating attacker can additionally capture the client's mutual TLS certificate exchange and observe smartcard operations. No public exploit or CISA KEV listing exists at time of analysis.
Command injection in Microsoft Copilot Web (copilot_web) enables unauthenticated remote attackers to exfiltrate sensitive data over the network by embedding malicious command elements in user-controlled input. The impact is strictly bounded to confidentiality - no integrity or availability loss - and a proof-of-concept is publicly available on GitHub. Despite a CVSS 7.5 score and public PoC, SSVC classifies exploitation as none with Automatable=no, and EPSS sits at 1.63%, suggesting limited real-world exploitation activity at time of analysis.
Path traversal on Windows-hosted DataEase instances allows unauthenticated remote attackers to read arbitrary files from the server filesystem by exploiting a filter bypass unique to the Windows backslash path separator. All DataEase versions prior to 2.10.23 on Windows are affected; the root cause is that string truncation logic blocks only the forward-slash but not the backslash, which Windows treats as an equivalent directory separator. No public exploit has been identified at time of analysis, but the vendor-confirmed CVSS 4.0 score of 8.7 with a network-accessible, no-privileges vector warrants immediate patching on any Windows deployment.
Tamper protection bypass in BeyondTrust Endpoint Privilege Management (EPM) for Windows allows local high-privileged users to circumvent agent protection controls by exploiting a flaw in how protections are applied to a support utility process. Affected versions are all EPM Windows Deployment releases prior to 26.1.2, per EUVD-2026-60270 and BeyondTrust advisory BT26-04. No public exploit has been identified and this is not in CISA KEV, but the high confidentiality, integrity, and availability impact on the vulnerable system makes this a meaningful concern for any organization relying on EPM as a core endpoint security control.
Memory corruption in the kernel-mode driver component of BeyondTrust Endpoint Privilege Management for Windows (all versions prior to 26.1.2) allows a low-privileged local user to trigger an out-of-bounds read, potentially disclosing kernel memory contents or corrupting system state. The flaw is rooted in insufficient input validation within a Ring 0 component - the most privileged execution layer on Windows - amplifying the potential impact of what would otherwise be a constrained user-level action. No public exploit code or confirmed active exploitation has been identified at time of analysis, and the vendor has released a fix in version 26.1.2.
Redirect URI prefix-matching in Medplum's unauthenticated external IdP callback (GET /auth/external) allows an attacker who can forge or intercept the OAuth state parameter to redirect Medplum authorization codes and login tokens to an attacker-controlled endpoint. All deployments of npm/@medplum/core at version 5.1.5 and below where a ClientApplication has an external identityProvider configured are affected; the fix was released in v5.1.6. Publicly available exploit code exists in the GHSA-m44r-7c5h-m6mj advisory - including curl-based reproduction steps - and because the attacker can inject their own PKCE challenge into the forged state, stolen codes can be redeemed for a full access token without the victim's knowledge, constituting a complete account takeover.
Local privilege escalation in SiYuan before 3.7.4 allows a low-privileged local attacker to execute arbitrary commands with administrator privileges by crafting a workspace directory whose path contains OS command metacharacters. When the victim triggers the Microsoft Defender exclusion workflow within SiYuan and approves the resulting UAC prompt, the application passes the unsanitized path to the elevated elevator.exe helper process, enabling command injection at administrator level. No public exploit code has been identified at time of analysis, but the CVSS 4.0 score of 8.6 reflects the full-system compromise potential once the attack preconditions are met.
Silent OAuth 1.0a-to-1.0 protocol downgrade in the Perl module Net::OAuth::Client (versions before 0.32) lets a service provider strip the anti-session-fixation protection an application explicitly requested. When an app configures a callback (selecting 1.0a) but the provider's request-token response omits oauth_callback_confirmed, get_request_token silently reverts to OAuth 1.0, which drops the oauth_verifier from the access-token exchange with no exception or warning, re-exposing the app to OAuth session fixation. No public exploit identified at time of analysis; EPSS is low (0.21%) and this is not in CISA KEV, but the fix is vendor-confirmed in release 0.32.
Race condition in the Linux kernel's CAN ISO-TP (isotp) socket subsystem allows adjacent-network attackers to corrupt TX state machine transitions, enabling kernel memory corruption with high confidentiality, integrity, and availability impact. Multiple stable branches from 5.10 onward are affected, with fixes released in kernel versions 6.6.148, 6.12.101, 6.18.40, 7.1.5, and 7.2-rc4. No public exploit code or CISA KEV entry has been identified at time of analysis, and the EPSS probability of exploitation within 30 days is 0.21% (11th percentile), consistent with the narrow, specialized conditions required.
Heap overflow in the Linux kernel brcmfmac/cyw WiFi driver allows a network-adjacent attacker controlling a rogue or compromised access point to corrupt kernel heap memory during WPA3 SAE authentication. The flaw in `brcmf_notify_auth_frame_rx()` causes an unsigned integer underflow when a short auth frame (under 24 bytes) is received, producing a wrap-around copy length that drives `memcpy` far beyond the allocated buffer. With CVSS 8.8 and full C/H/I/H/A/H impact on the vulnerable system, exploitation yields arbitrary kernel memory write capability; no public exploit has been identified at time of analysis and EPSS sits at 0.21% (12th percentile), indicating low observed exploitation pressure despite the critical technical severity.
Elevation of privilege in the Microsoft Malware Protection Engine (Microsoft Defender), publicly named 'ShieldBreak', allows a locally authenticated low-privileged user to gain high-level system access. The CVSS vector confirms a local, low-complexity attack requiring only low privileges and no user interaction, with full confidentiality, integrity, and availability impact. Proof-of-concept exploit code exists (E:P in the temporal vector), and Microsoft has acknowledged the vulnerability publicly.
Command injection in Microsoft PowerShell 7.4, 7.5, and 7.6 allows a locally authenticated attacker with standard user privileges to execute arbitrary code on the affected system. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms exploitation requires only local access and a low-privileged account - no elevated rights, user interaction, or complex conditions are needed. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity lowers the bar for exploitation once an injection point is discovered.
Remote code execution in Microsoft Edge (Chromium-based) is enabled by a heap-based buffer overflow (CWE-122) that network-accessible, unauthenticated attackers can trigger when a victim interacts with attacker-controlled content. The CVSS 3.1 score of 8.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:L) reflects high confidentiality and integrity impact with low attack complexity, requiring only that the user visit or open a crafted resource. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Account takeover in Authorizer's OAuth callback handler allows an unauthenticated attacker to pre-stage persistent backdoor access to any victim account by registering an unverified email address before the victim completes a routine OAuth login. The attack exploits a trust boundary violation in `internal/http_handlers/oauth_callback.go` (lines 125-219): the handler merges any incoming OAuth identity into the first database account matching by email, auto-verifies that account's email, and never invalidates the original password - leaving the attacker's credential fully active. No public exploit code has been independently confirmed, but the GHSA advisory contains a complete, line-referenced attack chain that makes independent reproduction trivial.
Horizontal privilege escalation / cross-account file access in FileBrowser before 2.63.19 lets a self-registering user take over another user's files when the server runs on a case-insensitive filesystem (e.g. Windows/NTFS). Because the home-directory ownership scope is persisted and compared as an exact case-sensitive string, two signups differing only in letter case (e.g. CaseVictim vs casevictim) become separate accounts that map to the same physical directory, giving the second registrant read, overwrite, and delete access to the first user's data over authenticated HTTP. Reported by VulnCheck; a vendor patch is available and no public exploit has been identified at time of analysis.
Arbitrary code execution in IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 on Windows is enabled by a publicly writable directory created when the application is installed in 'all users' mode. A local attacker with low privileges can plant malicious content in this directory, which the application subsequently loads with higher-privilege context, achieving full code execution. No active exploitation is confirmed (not in CISA KEV), and the EPSS score of 0.11% (2nd percentile) reflects low observed exploitation pressure, though the SSVC technical impact rating is 'total', underscoring the severity if exploited.
Privilege escalation in Lenovo Accessories and Display Manager for Enterprise for Windows allows a local authenticated user with low-level privileges to execute arbitrary code at elevated privilege levels, stemming from a hard-coded cryptographic key (CWE-321). The vulnerability was surfaced during an internal Lenovo security assessment and affects all versions of the product per the CPE wildcard. No public exploit code or CISA KEV listing is identified at time of analysis; a vendor patch is confirmed available via Lenovo advisory LEN-213038.
File Browser versions 2.50.0 through 2.63.21 permit indefinite session persistence via expired JWT tokens when proxy authentication is configured with a non-default logout page, enabling an attacker who possesses any previously valid token to access protected routes and administrative endpoints beyond the token's expiration window. The authentication middleware intentionally waived JWT expiration under proxy-auth - since the proxy is expected to govern session lifetime - but failed to require the proxy to simultaneously assert the user's identity on each request, meaning a leaked or captured token could authenticate independently and indefinitely. No public exploit code has been identified at time of analysis; the fix commit and vendor security advisory are publicly available.
Authenticated remote code execution in UpSnap (a self-hosted Wake-on-LAN web app) before 5.4.0 lets any low-privileged user with device create/edit permission run arbitrary OS commands on the server. User-supplied device IP and MAC values are interpolated into the wake_cmd/shutdown_cmd shell templates and passed unsanitized to /bin/sh -c on Linux or cmd /C on Windows, giving full command execution in the app's process context. No public exploit was identified at time of analysis and it is not in CISA KEV, but the flaw is trivially triggerable at low attack complexity once an account exists; a companion setup-wizard flaw (GHSA-w4jr-728f-5jhq) can let an attacker seize the first superuser on un-provisioned public instances and chain into this RCE.
Arbitrary code execution is achievable on Windows endpoints running IBM i Access Client Solutions (ACS) 1.1.2.0 through 1.1.9.13 when the software is installed in all-users mode, because the installer leaves one or more configuration files world-writable. Any local user with standard (non-administrator) privileges can modify these files to inject code that executes under the security context of other users who subsequently launch the application. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the CVSS 7.8 High rating reflects the full confidentiality, integrity, and availability impact achievable once a local foothold exists.
Command injection in Shescape (npm shell-escaping library) versions below 2.1.14 and the 3.0.x line below 3.0.1 allows an attacker-controlled argument to break out of a parenthesized cmd.exe construct and inject arbitrary shell syntax on Windows. The flaw affects applications that call the escape or escapeAll APIs with shell set to cmd.exe (or shell:true when CMD is the default), because getEscapeFunction in src/internal/win/cmd.js failed to escape the ( and ) characters. A working proof-of-concept payload is published in the vendor advisory; there is no CISA KEV listing and no evidence of active exploitation at time of analysis.
Authentication bypass via spoofing in Dell Display and Peripheral Manager (DDPM) for Windows, versions prior to 2.3.0.17, enables local low-privileged attackers to escalate their privileges and execute arbitrary code on affected systems. The flaw (CWE-290) allows an attacker already present on the system to spoof an authenticated identity, circumventing DDPM's internal access controls. Dell has released a patched version (2.3.0.17) via advisory DSA-2026-320; no public exploit or CISA KEV listing has been identified at time of analysis.
Elevation of privilege and arbitrary code execution in Dell Display and Peripheral Manager (DDPM) for Windows, all versions prior to 2.3.0.17, is achievable by a low-privileged local attacker exploiting an authentication bypass by spoofing flaw. The CWE-284 root cause - improper access control - allows the attacker to circumvent DDPM's privilege verification, resulting in full confidentiality, integrity, and availability compromise on the affected host. No active exploitation has been confirmed by CISA KEV and no public exploit code has been identified at time of analysis; Dell has released the corrective patch in version 2.3.0.17 via advisory DSA-2026-320.
Elevation of privilege and arbitrary code execution in Dell Display and Peripheral Manager (DDPM) for Windows allows a low-privileged local attacker on affected systems to bypass access controls and run code at a higher privilege level. All DDPM versions prior to 2.3.0.17 are affected, as confirmed by Dell advisory DSA-2026-320. No public exploit code or CISA KEV listing has been identified at time of analysis, though tags indicate RCE and authentication bypass primitives are involved, consistent with the CWE-284 root cause.
Local privilege escalation in Dell Display and Peripheral Manager (DDPM) for Windows enables a low-privileged local attacker to bypass access controls and execute arbitrary code at elevated privileges, affecting all versions prior to 2.3.0.17. The root cause is an improper access control flaw classified as CWE-290 (Authentication Bypass by Capture-replay), through which a standard user account can subvert DDPM's privileged service process and achieve system-level code execution. Dell has released version 2.3.0.17 via advisory DSA-2026-320, and no public exploit or active exploitation has been identified at time of analysis.
Server-side template injection leading to remote code execution in Microsoft's @prompty/core npm package (TypeScript runtime) allows an attacker who controls a .prompty template body to execute arbitrary JavaScript in the host Node.js process. The flaw affects @prompty/core versions <= 0.1.4 and the 2.0.0-alpha.1 through 2.0.0-beta.4 pre-releases, where the Nunjucks renderer permitted unrestricted member access, letting a malicious template walk constructor/prototype chains to reach a JavaScript execution primitive. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the maximum CVSS of 10.0 and CWE-94 code-injection root cause make this a critical-priority patch for any app that renders untrusted, community-supplied, cloned, or LLM-generated .prompty files.
Insecure Direct Object Reference in Microsoft Container Migration Solution Accelerator version 2.1.2 and earlier enables any authenticated organization member to read, overwrite, and delete migration processes and files belonging to other users within the same tenant. The application delegates identity verification to Entra ID but implements no per-resource ownership checks across its process and file management API endpoints, meaning the authentication boundary is entirely decoupled from the authorization boundary. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity and full confidentiality, integrity, and availability impact on application data make this a high-priority remediation target for any multi-user deployment.
Missing authentication in Microsoft UFO's mobile MCP servers lets an unauthenticated remote attacker fully control an ADB-connected Android device before version 3.0.8. The create_mobile_data_collection_server and create_mobile_action_server components bind Streamable HTTP MCP services to TCP 8020 and 8021 with no credential check, exposing tools such as capture_screenshot, get_ui_tree, tap, swipe, type_text, launch_app, press_key, and click_control to anyone who can reach the ports. No public exploit identified at time of analysis, but the fix (adding UFO_MCP_API_KEY bearer auth) is confirmed in the vendor advisory GHSA-24fq-m9rr-g3mm and release v3.0.8, and the high EPSS-relevant impact (CVSS 9.4) makes this a serious exposure wherever the mobile agent is run on a reachable interface.
URLSecurityValidator SSRF bypass in compliance-trestle <= 4.0.3 allows a network-positioned attacker to reach cloud metadata services, loopback admin interfaces, and RFC 1918 internal networks by embedding IPv4-mapped IPv6 literals (e.g., [::ffff:169.254.169.254]) or the unspecified address 0.0.0.0 in OSCAL artifact import references processed by HTTPSFetcher or SFTPFetcher. Python's ipaddress module silently returns False - rather than raising TypeError - when comparing IPv6Address objects against IPv4Network ranges, so the validator's membership checks pass these forms through to requests.get unchanged. A publicly available proof-of-concept reproduces end-to-end IMDS credential exfiltration; no active exploitation is listed in CISA KEV and EPSS stands at 0.42%.
Sandbox escape in Cursor IDE for macOS prior to version 3.1.2 allows an AI agent operating in Auto-Run Sandbox mode to replace a Python virtual environment executable with a malicious wrapper, which the Microsoft Python extension then invokes outside the sandbox boundary - granting arbitrary host command execution with the user's full macOS privileges, including modifying files outside the workspace and launching applications. The vulnerability exploits a privileged trust relationship between the sandboxed agent and an unsandboxed host-level extension. No active exploitation has been confirmed (not in CISA KEV), and no public exploit code has been identified at time of analysis; a vendor-released patch is available in version 3.1.2.
CSV formula injection in Typebot 3.16.1's result-export feature lets remote, unauthenticated chatbot users embed spreadsheet formulas (e.g. =, +, -, @) into form input fields that are written unsanitized into exported CSV files; when an administrator opens the export in Excel or LibreOffice Calc, the injected formula executes in the admin's context. Tracked as CWE-1236 with a vendor CVSS of 9.6 (scope-changed), it is patched in 3.17.0. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote code execution affects Microsoft Azure Attestation service and Device Health Attestation Service via an integer overflow condition that leads to a heap-based buffer overflow (CWE-122). Unauthenticated network attackers can exploit this flaw - confirmed by PR:N in the CVSS vector - though the high attack complexity (AC:H) indicates precise exploitation conditions must be met. No public exploit code or CISA KEV listing has been identified at time of analysis, but the potential impact is critical: full compromise of confidentiality, integrity, and availability on the affected service.
Privilege escalation via stored cross-site scripting in Microsoft SharePoint Server allows an authenticated low-privileged attacker to elevate their rights over a network by injecting malicious script that executes in a victim's browser session. Affected products include SharePoint Server 2019 and Subscription Edition with specific unpatched builds. No active exploitation has been confirmed - SSVC rates exploitation as none, EPSS stands at 0.42% (35th percentile), and the CVE is not listed in CISA KEV - though the CVSS-rated technical impact is classified as total due to high confidentiality and integrity compromise enabled by the scope change.
Local code execution via out-of-bounds write in Microsoft .NET allows an unauthenticated local attacker to achieve full code execution upon successful exploitation, with high impact across confidentiality, integrity, and availability. The vulnerability requires user interaction - such as opening a malicious file or running a crafted application - making social engineering a likely delivery vector. No public exploit code or CISA KEV listing has been identified at time of analysis, though the Microsoft Security Response Center has acknowledged the issue.
Privilege escalation via heap-based buffer overflow in Windows Installer (msiexec) allows a low-privileged local user to gain full system control. Affected product is Microsoft Windows across versions that ship with the vulnerable Windows Installer component; exact version scope is defined by the MSRC advisory. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA's KEV catalog, though its low-complexity, no-user-interaction profile makes it a realistic post-foothold escalation tool.
Stack-based buffer overflow in the Windows Installer component (msiexec) enables local privilege escalation to SYSTEM on affected Windows systems. An attacker holding any standard local user account can trigger the overflow with low complexity and no user interaction required, achieving full compromise of confidentiality, integrity, and availability. No public exploit has been identified at time of analysis, and this vulnerability does not appear in the CISA KEV catalog based on available data.
Privilege escalation in Windows Installer exposes all supported Windows systems to SYSTEM-level compromise by any low-privileged local user. The heap-based buffer overflow (CWE-122) in the Installer service requires only an authenticated local session - no user interaction, no elevated credentials, and low attack complexity per CVSS:3.1/AV:L/AC:L/PR:L/UI:N. No public exploit code or active exploitation via CISA KEV has been identified at time of analysis, but the ubiquity of Windows Installer and the straightforward exploitation conditions make this a meaningful post-compromise escalation primitive.
Local privilege escalation in Windows Installer (msiexec) stems from a stack-based buffer overflow (CWE-121) exploitable by any authenticated local user. An attacker with low-privilege access on an affected Windows system can trigger the overflow to gain full SYSTEM-level control, achieving complete confidentiality, integrity, and availability compromise of the local host. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity and broad Windows deployment footprint make this a meaningful priority for patch management.
Privilege escalation in Microsoft Azure CycleCloud (versions prior to 8.9.1) allows an authenticated low-privilege network attacker to elevate to higher privilege levels due to missing authorization checks (CWE-862). The CVSS 8.8 score reflects high impact across confidentiality, integrity, and availability with no user interaction required, though exploitation demands valid credentials. No public exploit has been identified at time of analysis, and this vulnerability has not been added to the CISA KEV catalog, though SSVC rates the technical impact as total.
Code injection (CWE-94) in Microsoft PowerShell enables a local, unauthenticated attacker to bypass a security feature through user interaction, resulting in high-impact compromise of confidentiality, integrity, and availability. The CVSS 3.1 score of 7.8 reflects a local attack vector requiring user interaction, with no privileges needed from the attacker. No public exploit code or CISA KEV listing has been identified at time of analysis, but the RCE tag and full C/I/A impact make this a priority for environments running PowerShell on Windows.
Remote code execution in Microsoft PowerShell Core is achievable by unauthenticated network attackers exploiting a relative path traversal flaw (CWE-23), provided the victim performs some user interaction. The CVSS 8.8 score reflects high confidentiality, integrity, and availability impact with no privilege requirement on the attacker's side, making this a significant threat in enterprise environments where PowerShell Core is ubiquitous. No public exploit code or CISA KEV listing has been identified at time of analysis, but the Microsoft Security Response Center has published an advisory.
Remote code execution in Microsoft Visual Studio Code allows a network-based attacker to inject and execute arbitrary code on a victim's machine with no prior authentication, provided the victim performs a user interaction - such as opening a malicious workspace, file, or URI. Classified under CWE-94 (Code Injection), the vulnerability carries a CVSS base score of 8.8, reflecting high impact across confidentiality, integrity, and availability. No public exploit code or CISA KEV listing was identified at the time of analysis, but the attack complexity is rated Low, making reliable exploitation straightforward once a victim is lured.
OS command injection in GitHub Copilot and Visual Studio Code enables a local unauthorized attacker to escalate privileges on the affected developer workstation, achieving full High impact across confidentiality, integrity, and availability. The CWE-78 root cause indicates that attacker-influenced input containing shell metacharacters is improperly incorporated into OS-level command execution within one or both products, triggering upon a user action such as opening a malicious file or repository. No public exploit code has been identified and this vulnerability has not been confirmed actively exploited by CISA KEV at time of analysis; however, the local privilege escalation path on widely deployed developer tooling represents a meaningful risk in supply chain and social engineering scenarios.
Privilege escalation via heap-based buffer overflow in the Windows DNS component affects Windows 10, Windows 11, and Windows Server editions spanning Server 2012 through Server 2025. An authorized local attacker holding low-privilege credentials can trigger the overflow to achieve full system compromise (C:H/I:H/A:H). No public exploit code or active exploitation has been identified at time of analysis; a vendor-released patch is available through the Microsoft Security Response Center advisory.
Remote code execution in Microsoft Office Outlook stems from an integer overflow or wraparound condition (CWE-190) that allows an unauthenticated network attacker to execute arbitrary code on a victim's system, achieving full confidentiality, integrity, and availability compromise. The CVSS 3.1 score of 8.8 (High) with vector AV:N/AC:L/PR:N/UI:R reflects low attack complexity and no authentication requirement, though exploitation is gated by a user interaction step. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the attack profile is consistent with phishing-delivered malicious email or attachment campaigns targeting Outlook users.
Privilege escalation via SSRF in Microsoft Office SharePoint exposes authenticated users to full system compromise - confidentiality, integrity, and availability all rated High. The CVSS vector (PR:L/AV:N/AC:L/UI:N) confirms that any authenticated SharePoint user can trigger the vulnerability over the network without additional complexity. No active exploitation or public exploit code has been identified at time of analysis, though the low attack complexity and broad privilege impact make this a credible near-term risk.
Server-side request forgery in Microsoft Office SharePoint enables low-privileged authenticated attackers to escalate privileges with no user interaction required, achieving high confidentiality, integrity, and availability impact. The flaw (CWE-918) allows a legitimate but low-privilege account holder to forge server-side HTTP requests, likely reaching internal administrative interfaces or credential endpoints inaccessible from the network perimeter. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Remote code execution in Microsoft Office SharePoint allows an attacker authenticated with low privileges to execute arbitrary code over a network via unsafe deserialization of user-controlled data. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) confirms full confidentiality, integrity, and availability impact with no user interaction required. No public exploit code has been identified at time of analysis, and SharePoint is not currently listed in the CISA KEV catalog based on available data.
PowerPoint's improper input validation (CWE-20) exposes local users to high-impact compromise when a maliciously crafted presentation file is opened, with the official CVSS vector asserting high confidentiality, integrity, and availability impact - a notable divergence from the description's characterization as information disclosure only. The attack requires no attacker privileges but mandates user interaction, fitting a phishing-and-open-file threat model. No public exploit code exists and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
Use-after-free memory corruption in Microsoft Office Word enables local code execution when a user opens a specially crafted document. The CVSS vector (AV:L/AC:L/PR:N/UI:R) confirms this is a social-engineering-dependent attack - no system privileges are required, but the victim must open a malicious file, making phishing or drive-by document delivery the likely delivery mechanism. All three impact dimensions (Confidentiality, Integrity, Availability) are rated High, yielding a 7.8 CVSS score; no public exploit or CISA KEV listing has been identified at time of analysis.
Local privilege escalation in the Windows Ancillary Function Driver for WinSock (afd.sys) allows a low-privileged local attacker to gain full system control through a use-after-free memory corruption condition. The CVSS vector (AV:L/AC:H/PR:L) confirms the attack is constrained to local access with high complexity, meaning exploitation is non-trivial and likely requires precise timing or race condition triggering. No public exploit code and no CISA KEV listing have been identified at time of analysis, though the tags indicate Denial of Service is also a potential impact alongside privilege escalation.
Cross-site scripting in Microsoft Office SharePoint lets a remote, unauthenticated attacker inject script that executes in a victim's browser session to conduct spoofing, provided the victim is lured into interacting with the malicious content. Microsoft rates it 9.3 (Critical) with a scope-changed vector, reflecting that injected script escapes into the victim's authenticated SharePoint context. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Heap-based buffer overflow in the Windows DNS component enables a locally authenticated low-privileged attacker to escalate privileges to SYSTEM across a broad range of Windows releases, from Windows 10 version 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025. The CVSS 3.1 score of 7.8 reflects low attack complexity and full confidentiality, integrity, and availability impact once local access is obtained, with no user interaction required. No public exploit code or active exploitation has been identified at time of analysis, and a vendor-released patch is available via the Microsoft Security Response Center.
Heap-based buffer overflow in Microsoft Office (365 Apps for Enterprise, Office 2019, Office 2021 LTSC, and Office 2024 LTSC) enables a local attacker with low-privilege credentials to execute arbitrary code with the full confidentiality, integrity, and availability impact of the Office process. The vulnerability (CWE-122) carries a CVSS 3.1 score of 7.8 and requires only local access and a standard user account - no user interaction is needed once the attacker can trigger the vulnerable allocation path. No public exploit code has been identified at time of analysis, and SSVC assessment confirms current exploitation status as none.
OS command injection in Visual Studio Code exposes victims to remote code execution when they interact with attacker-controlled content, such as a malicious workspace, repository, or file. The vulnerability (CWE-78) stems from improper neutralization of shell metacharacters in input passed to OS-level command execution routines, giving an unauthenticated network attacker the ability to run arbitrary commands with the privileges of the VS Code process. No active exploitation has been confirmed by CISA KEV, and no public proof-of-concept is referenced at time of analysis.
Fail-open security logic in Visual Studio Code permits network-based security feature bypass by an unauthenticated attacker who can induce user interaction. The root cause is CWE-636: when the application encounters an error or edge condition in a security enforcement path, it defaults to granting rather than denying access, neutralizing the intended control. With a CVSS score of 8.2 and a scope-changed vector (S:C) paired with high confidentiality impact, successful exploitation could expose data or capabilities beyond the direct VS Code process boundary. No public exploit code or CISA KEV listing has been identified at time of analysis.
Local security feature bypass in Visual Studio Code allows an attacker with local access to circumvent an authorization control, achieving high-impact compromise of confidentiality, integrity, and availability on the affected system. The vulnerability (CWE-693, Protection Mechanism Failure) is exploitable locally without elevated privileges but requires user interaction, making social engineering or physical access the likely delivery path. No public exploit code or active exploitation has been identified at time of analysis.
Privilege escalation in Windows App Installer (the App Installer component of Windows Package Manager, aka winget) allows an authenticated local attacker with standard user privileges to fully compromise confidentiality, integrity, and availability of the affected system. The flaw stems from improper privilege management (CWE-269), meaning the application fails to correctly enforce privilege boundaries during its operations. No active exploitation is confirmed - CISA KEV does not list this CVE, SSVC rates exploitation as 'none', and EPSS sits at only 0.33% (26th percentile) - but the SSVC technical impact rating of 'total' reflects the severity of a successful local privilege escalation to full system control.
Privilege escalation in the Windows Ancillary Function Driver for WinSock (afd.sys) allows a locally authenticated attacker to gain SYSTEM-level privileges through a use-after-free memory corruption flaw. Affected systems include Windows installations where the WinSock subsystem is active, which covers virtually all Windows deployments. No public exploit code or active exploitation has been identified at time of analysis, though the high-complexity exploitation bar somewhat limits immediate opportunistic risk.
Remote unauthenticated denial of service in Windows Network File System (NFS) allows a network attacker to crash the NFS service by sending a malformed packet that triggers a buffer over-read (CWE-126). Affected systems span Windows Server 2012 through 2025 and Windows 10 versions 1607 and 1809. No public exploit code has been identified at time of analysis, and CISA has not added this to the Known Exploited Vulnerabilities catalog; Microsoft has released patches across all affected build lines.

The vulnerability (CWE-125) carries a CVSS 7.8 score with high impact across confidentiality, integrity, and availability, and is reported directly by Microsoft via the MSRC update guide. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity (AC:L) indicates reliable exploitability once a working exploit is developed.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a user opens a specially crafted Excel file. The vulnerability triggers during file parsing, allowing an attacker who can deliver a malicious document to execute arbitrary code with the privileges of the logged-in user. No KEV listing or public exploit code has been identified at time of analysis, but the local-execution-via-document vector makes this a meaningful phishing and spear-phishing enabler.
Type confusion (CWE-843) in Microsoft Office Excel enables local code execution when a victim opens a specially crafted file. The CVSS vector (AV:L/AC:L/PR:N/UI:R) confirms the attack is file-based: no attacker privileges are required, but the target user must open a malicious document, making this a high-impact phishing-delivery vector. No public exploit code and no CISA KEV listing are identified at time of analysis, but the full confidentiality, integrity, and availability impact (C:H/I:H/A:H) makes this a critical priority for organizations where Excel is deployed.
Untrusted pointer dereference in Microsoft Office Excel enables local arbitrary code execution when a user opens a crafted document. The flaw (CWE-822) allows an attacker who can deliver a malicious file to achieve full code execution with high confidentiality, integrity, and availability impact on the victim's system. No public exploit has been identified at time of analysis, and Microsoft has not listed this in CISA's Known Exploited Vulnerabilities catalog.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a user opens a specially crafted file, granting full confidentiality, integrity, and availability compromise of the affected system. The CVSS vector (AV:L/AC:L/PR:N/UI:R) confirms this is a document-triggered exploit requiring no attacker privileges but demanding victim interaction - a profile consistent with malicious email attachment or drive-by download campaigns. No public exploit code or CISA KEV listing has been identified at time of analysis, though Excel's ubiquity makes this a high-value target class.
Out-of-bounds write (CWE-787) in Microsoft Office Excel enables local code execution when a user opens a specially crafted Excel file, yielding full confidentiality, integrity, and availability impact at CVSS 7.8. The attack is file-delivery based - typical phishing or drive-by download - requiring no system privileges from the attacker but requiring the victim to open the malicious document. No public exploit code or CISA KEV listing has been identified at time of analysis.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a user opens a specially crafted Excel file. The CVSS vector (AV:L/PR:N/UI:R) confirms the attack requires no system privileges but does require user interaction - the classic malicious-document delivery pattern. Full confidentiality, integrity, and availability compromise results, making this a high-severity threat against any organization reliant on Excel for document workflows. No public exploit or CISA KEV listing has been identified at time of analysis.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution with full system impact when a victim opens a maliciously crafted workbook. The root cause is a numeric truncation error (CWE-122) in Excel's file parsing logic, where an integer value is truncated before being used to size a heap allocation, resulting in an undersized buffer that can be overflowed. No public exploit code has been identified at time of analysis, and there is no CISA KEV listing, but the high CVSS score of 7.8 and full confidentiality, integrity, and availability impact make this a meaningful risk for organizations relying on Excel file workflows.
Type confusion (CWE-843) in Microsoft Office Excel enables local code execution by an unauthenticated attacker when a victim opens a specially crafted Excel document. The CVSS:3.1 vector (AV:L/AC:L/PR:N/UI:R) confirms this is a file-borne attack requiring user interaction but no attacker privileges, with full High/High/High C/I/A impact. No public exploit code or CISA KEV listing has been identified at time of analysis, though the memory corruption tag suggests the type confusion leads to exploitable heap or stack corruption.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a victim opens a specially crafted workbook, resulting in full compromise of confidentiality, integrity, and availability on the local system. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) confirms no attacker privileges are required, though user interaction - opening the malicious file - is a hard prerequisite. No public exploit code or CISA KEV listing has been identified at time of analysis; the issue is confirmed by Microsoft's Security Response Center via secure@microsoft.com.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a victim opens a specially crafted Excel file. The attack requires no privileges from the attacker but does require user interaction - consistent with a malicious document delivery vector - and carries high impact across confidentiality, integrity, and availability. No active exploitation (KEV) or public exploit code has been identified in the provided intelligence at time of analysis.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a victim opens a specially crafted file. The CVSS vector (AV:L/PR:N/UI:R) confirms exploitation requires no prior privileges but depends on user interaction - consistent with a malicious document delivery scenario. No public exploit code or CISA KEV listing has been identified at time of analysis, though the full confidentiality, integrity, and availability impact (C:H/I:H/A:H) makes this a high-severity concern for any environment running unpatched Excel installations.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a user opens a specially crafted Excel file. An unauthenticated attacker (per CVSS PR:N) delivers a malicious document that triggers the overflow upon interaction (UI:R), achieving full confidentiality, integrity, and availability compromise on the victim system. No public exploit or KEV listing has been identified at time of analysis, though the attack pattern is well-understood and document-based Excel exploits have a long operational history.
Stack-based buffer overflow in Microsoft Office Excel enables arbitrary code execution on the victim's local machine when a specially crafted Excel file is opened. The vulnerability carries a CVSS base score of 7.8 with high confidentiality, integrity, and availability impact, affecting the victim's user-level security context. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, reducing immediacy compared to actively exploited file-format parsing flaws.
Heap-based buffer overflow in Microsoft Office Excel enables local code execution when a victim opens a maliciously crafted file. The vulnerability (CWE-122) corrupts heap memory in Excel's parsing logic, allowing an attacker to achieve full control over confidentiality, integrity, and availability of the affected system. No public exploit or active exploitation has been identified at time of analysis, but the CVSS score of 7.8 with high impact across all three CIA triad pillars makes this a meaningful priority for organizations running affected Excel versions.
Out-of-bounds read in Microsoft Office Excel enables local code execution when a user opens a specially crafted workbook file. The CVSS vector (AV:L/AC:L/PR:N/UI:R) confirms file-based delivery requiring victim interaction, achieving full confidentiality, integrity, and availability impact on the compromised host. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Local privilege escalation in Microsoft Office exploits a command injection flaw (CWE-77) that allows an authenticated local attacker to gain elevated privileges on the affected system. The vulnerability requires only low-level privileges to trigger, making it accessible to any standard user account on a compromised or shared system. No public exploit code or CISA KEV listing is identified at time of analysis, but the high-impact CVSS score and Microsoft's own disclosure warrant prompt patching.
Remote code execution in Microsoft Office SharePoint exploits unsafe deserialization of attacker-controlled data over the network. An authenticated attacker with low-level network access can submit a crafted serialized payload that SharePoint deserializes without sufficient validation, resulting in full compromise of confidentiality, integrity, and availability. No public exploit has been identified at time of analysis, but the low attack complexity and high impact across all three security properties make this a critical remediation priority.
Stack-based buffer overflow in Microsoft Office enables local arbitrary code execution when a user opens a specially crafted document. The CVSS vector (AV:L/AC:L/PR:N/UI:R) confirms exploitation is local and requires user interaction - most likely triggered by opening a maliciously crafted Office file delivered via phishing or other social engineering. No active exploitation has been confirmed (not listed in CISA KEV) and no public exploit code has been identified at time of analysis, though the high-impact triad (C:H/I:H/A:H) and Microsoft Office's ubiquitous deployment footprint make this a notable patching priority.
Remote code execution in Microsoft Office SharePoint enables any authenticated low-privileged user to execute arbitrary code on the server by submitting maliciously crafted serialized data over the network. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) confirms the attack requires no user interaction, low complexity, and only a standard SharePoint account - making this straightforward to weaponize within any organization whose SharePoint is network-accessible to internal users or external authenticated parties. No public exploit code or CISA KEV listing is identified at time of analysis, though SharePoint deserialization vulnerabilities have historically attracted rapid weaponization.
Privilege escalation in the Windows Telephony Service (TapiSrv) allows an authenticated local attacker with low-privilege access to gain SYSTEM-level privileges by exploiting a race condition in how the service handles concurrent access to shared resources. Affected products span Windows 10 (multiple feature releases), Windows 11, and Windows Server 2012 through 2025, representing a broad swath of the Microsoft ecosystem. No public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but a vendor patch is available via the Microsoft Security Response Center.
Remote code execution in Ozols Grupa OZOLS on Windows (all versions before 1.1.1233) stems from an abandoned automatic-update domain that the OzolsSQL client still trusts. Because updates are pulled over cleartext with no integrity or signature check, anyone who re-registers the lapsed domain (or performs a network MITM) can serve a malicious serv_update.vbs that the <db>_update SQL Server Agent job executes as ActiveScripting, yielding full host compromise. The flaw carries a CVSS 4.0 base of 10.0; it was reported by ENISA (EUVD-2026-62704) with a vendor patch available, and no public exploit or CISA KEV listing is identified at time of analysis.
Broken authorization in Flow-Like's Azure presign endpoint allows authenticated app members holding only `ExecuteEvents` permission to obtain Azure Blob Storage SAS tokens with read, write, delete, and list (`sp=rwdl`) access to application content - permissions they explicitly should not possess. Only self-hosted Flow-Like deployments prior to version 1.0.4 using Azure Blob Storage are affected; the vendor's hosted services (Flow-Like Studio and the hosted Web App, both AWS-backed) are explicitly excluded. No public exploit has been identified and the vulnerability is not listed in CISA KEV, but the flaw is mechanically straightforward to abuse given that the credential overprovision is a direct API response to a single authenticated request.
Stored cross-site scripting escalating to arbitrary OS command execution affects the SiYuan personal knowledge-management application through version 3.7.3. Because the '((' block-reference autocomplete popup renders a candidate block's name, alias, and memo fields into HTML without escaping, an attacker who controls those metadata fields can plant a self-firing payload that runs the moment a victim types '((' and surfaces the crafted block; SiYuan's Electron shell runs with nodeIntegration enabled, contextIsolation disabled, and no CSP, so the injected script reaches require('child_process') and executes host commands. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the XSS-to-RCE chain is fully described by the VulnCheck advisory and vendor GHSA.
Pre-account takeover in 4gaBoards before 3.3.8 allows a remote unauthenticated attacker to seize a victim's account before the victim ever logs in, by exploiting the SSO identity-linking logic. An attacker registers an unverified local account using the victim's email address; when the victim subsequently logs in via Google, GitHub, Microsoft, or OIDC SSO, the server locates the attacker's pre-registered account by email and links the verified SSO identity to it without confirming local account ownership, granting the attacker persistent password access to the now-SSO-linked account and all associated projects and data. No public exploit code or CISA KEV listing has been identified at time of analysis; the CVSS 8.8 score reflects the low attack complexity and high impact once victim interaction occurs.
Sandbox escape via link following in Google Chrome's CredentialProvider component on Windows allows a local attacker to execute arbitrary code outside the browser's security sandbox, affecting all Chrome versions prior to 151.0.7922.169. The vulnerability stems from improper symbolic link or junction resolution (CWE-59) in the CredentialProvider, a Windows-specific subsystem handling credential operations, enabling a local attacker to redirect file access operations to attacker-controlled paths. No public exploit code has been identified and CISA's SSVC assessment confirms no known exploitation; however, the full CIA triad impact and sandbox escape potential make this a meaningful local privilege boundary violation.
Full takeover of Oracle Identity Manager Connector versions 12.2.1.4.0 and 14.1.2.1.0 is achievable by a high-privileged, remote attacker exploiting the Microsoft Active Directory component via LDAP, with confirmed scope change impacting additional Oracle Fusion Middleware products. The vendor-assessed outcome is complete loss of confidentiality, integrity, and availability. No public exploit code or CISA KEV listing has been identified at time of analysis, placing this in the category of serious but not actively weaponized vulnerabilities pending patch application.
TLS certificate verification is globally disabled in fbeta-GmbH's ePA3-Service-OpenSource prior to version 1.3.0, exposing all traffic between the integration service and Germany's electronic patient record system and Konnektor devices to interception by network-positioned attackers. Both the primary TLS layer - via hardcoded `verify=False` in Python requests sessions across two independent modules - and the VAU protocol's application-layer certificate validation are broken simultaneously, eliminating all cryptographic trust anchors with no defense-in-depth fallback. On the Konnektor communication path, an impersonating attacker can additionally capture the client's mutual TLS certificate exchange and observe smartcard operations. No public exploit or CISA KEV listing exists at time of analysis.
Command injection in Microsoft Copilot Web (copilot_web) enables unauthenticated remote attackers to exfiltrate sensitive data over the network by embedding malicious command elements in user-controlled input. The impact is strictly bounded to confidentiality - no integrity or availability loss - and a proof-of-concept is publicly available on GitHub. Despite a CVSS 7.5 score and public PoC, SSVC classifies exploitation as none with Automatable=no, and EPSS sits at 1.63%, suggesting limited real-world exploitation activity at time of analysis.
Path traversal on Windows-hosted DataEase instances allows unauthenticated remote attackers to read arbitrary files from the server filesystem by exploiting a filter bypass unique to the Windows backslash path separator. All DataEase versions prior to 2.10.23 on Windows are affected; the root cause is that string truncation logic blocks only the forward-slash but not the backslash, which Windows treats as an equivalent directory separator. No public exploit has been identified at time of analysis, but the vendor-confirmed CVSS 4.0 score of 8.7 with a network-accessible, no-privileges vector warrants immediate patching on any Windows deployment.
Tamper protection bypass in BeyondTrust Endpoint Privilege Management (EPM) for Windows allows local high-privileged users to circumvent agent protection controls by exploiting a flaw in how protections are applied to a support utility process. Affected versions are all EPM Windows Deployment releases prior to 26.1.2, per EUVD-2026-60270 and BeyondTrust advisory BT26-04. No public exploit has been identified and this is not in CISA KEV, but the high confidentiality, integrity, and availability impact on the vulnerable system makes this a meaningful concern for any organization relying on EPM as a core endpoint security control.
Memory corruption in the kernel-mode driver component of BeyondTrust Endpoint Privilege Management for Windows (all versions prior to 26.1.2) allows a low-privileged local user to trigger an out-of-bounds read, potentially disclosing kernel memory contents or corrupting system state. The flaw is rooted in insufficient input validation within a Ring 0 component - the most privileged execution layer on Windows - amplifying the potential impact of what would otherwise be a constrained user-level action. No public exploit code or confirmed active exploitation has been identified at time of analysis, and the vendor has released a fix in version 26.1.2.
Redirect URI prefix-matching in Medplum's unauthenticated external IdP callback (GET /auth/external) allows an attacker who can forge or intercept the OAuth state parameter to redirect Medplum authorization codes and login tokens to an attacker-controlled endpoint. All deployments of npm/@medplum/core at version 5.1.5 and below where a ClientApplication has an external identityProvider configured are affected; the fix was released in v5.1.6. Publicly available exploit code exists in the GHSA-m44r-7c5h-m6mj advisory - including curl-based reproduction steps - and because the attacker can inject their own PKCE challenge into the forged state, stolen codes can be redeemed for a full access token without the victim's knowledge, constituting a complete account takeover.
Local privilege escalation in SiYuan before 3.7.4 allows a low-privileged local attacker to execute arbitrary commands with administrator privileges by crafting a workspace directory whose path contains OS command metacharacters. When the victim triggers the Microsoft Defender exclusion workflow within SiYuan and approves the resulting UAC prompt, the application passes the unsanitized path to the elevated elevator.exe helper process, enabling command injection at administrator level. No public exploit code has been identified at time of analysis, but the CVSS 4.0 score of 8.6 reflects the full-system compromise potential once the attack preconditions are met.
Silent OAuth 1.0a-to-1.0 protocol downgrade in the Perl module Net::OAuth::Client (versions before 0.32) lets a service provider strip the anti-session-fixation protection an application explicitly requested. When an app configures a callback (selecting 1.0a) but the provider's request-token response omits oauth_callback_confirmed, get_request_token silently reverts to OAuth 1.0, which drops the oauth_verifier from the access-token exchange with no exception or warning, re-exposing the app to OAuth session fixation. No public exploit identified at time of analysis; EPSS is low (0.21%) and this is not in CISA KEV, but the fix is vendor-confirmed in release 0.32.
Race condition in the Linux kernel's CAN ISO-TP (isotp) socket subsystem allows adjacent-network attackers to corrupt TX state machine transitions, enabling kernel memory corruption with high confidentiality, integrity, and availability impact. Multiple stable branches from 5.10 onward are affected, with fixes released in kernel versions 6.6.148, 6.12.101, 6.18.40, 7.1.5, and 7.2-rc4. No public exploit code or CISA KEV entry has been identified at time of analysis, and the EPSS probability of exploitation within 30 days is 0.21% (11th percentile), consistent with the narrow, specialized conditions required.
Heap overflow in the Linux kernel brcmfmac/cyw WiFi driver allows a network-adjacent attacker controlling a rogue or compromised access point to corrupt kernel heap memory during WPA3 SAE authentication. The flaw in `brcmf_notify_auth_frame_rx()` causes an unsigned integer underflow when a short auth frame (under 24 bytes) is received, producing a wrap-around copy length that drives `memcpy` far beyond the allocated buffer. With CVSS 8.8 and full C/H/I/H/A/H impact on the vulnerable system, exploitation yields arbitrary kernel memory write capability; no public exploit has been identified at time of analysis and EPSS sits at 0.21% (12th percentile), indicating low observed exploitation pressure despite the critical technical severity.
Elevation of privilege in the Microsoft Malware Protection Engine (Microsoft Defender), publicly named 'ShieldBreak', allows a locally authenticated low-privileged user to gain high-level system access. The CVSS vector confirms a local, low-complexity attack requiring only low privileges and no user interaction, with full confidentiality, integrity, and availability impact. Proof-of-concept exploit code exists (E:P in the temporal vector), and Microsoft has acknowledged the vulnerability publicly.
Command injection in Microsoft PowerShell 7.4, 7.5, and 7.6 allows a locally authenticated attacker with standard user privileges to execute arbitrary code on the affected system. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms exploitation requires only local access and a low-privileged account - no elevated rights, user interaction, or complex conditions are needed. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity lowers the bar for exploitation once an injection point is discovered.
Remote code execution in Microsoft Edge (Chromium-based) is enabled by a heap-based buffer overflow (CWE-122) that network-accessible, unauthenticated attackers can trigger when a victim interacts with attacker-controlled content. The CVSS 3.1 score of 8.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:L) reflects high confidentiality and integrity impact with low attack complexity, requiring only that the user visit or open a crafted resource. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Account takeover in Authorizer's OAuth callback handler allows an unauthenticated attacker to pre-stage persistent backdoor access to any victim account by registering an unverified email address before the victim completes a routine OAuth login. The attack exploits a trust boundary violation in `internal/http_handlers/oauth_callback.go` (lines 125-219): the handler merges any incoming OAuth identity into the first database account matching by email, auto-verifies that account's email, and never invalidates the original password - leaving the attacker's credential fully active. No public exploit code has been independently confirmed, but the GHSA advisory contains a complete, line-referenced attack chain that makes independent reproduction trivial.
Horizontal privilege escalation / cross-account file access in FileBrowser before 2.63.19 lets a self-registering user take over another user's files when the server runs on a case-insensitive filesystem (e.g. Windows/NTFS). Because the home-directory ownership scope is persisted and compared as an exact case-sensitive string, two signups differing only in letter case (e.g. CaseVictim vs casevictim) become separate accounts that map to the same physical directory, giving the second registrant read, overwrite, and delete access to the first user's data over authenticated HTTP. Reported by VulnCheck; a vendor patch is available and no public exploit has been identified at time of analysis.
Arbitrary code execution in IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 on Windows is enabled by a publicly writable directory created when the application is installed in 'all users' mode. A local attacker with low privileges can plant malicious content in this directory, which the application subsequently loads with higher-privilege context, achieving full code execution. No active exploitation is confirmed (not in CISA KEV), and the EPSS score of 0.11% (2nd percentile) reflects low observed exploitation pressure, though the SSVC technical impact rating is 'total', underscoring the severity if exploited.
Privilege escalation in Lenovo Accessories and Display Manager for Enterprise for Windows allows a local authenticated user with low-level privileges to execute arbitrary code at elevated privilege levels, stemming from a hard-coded cryptographic key (CWE-321). The vulnerability was surfaced during an internal Lenovo security assessment and affects all versions of the product per the CPE wildcard. No public exploit code or CISA KEV listing is identified at time of analysis; a vendor patch is confirmed available via Lenovo advisory LEN-213038.
File Browser versions 2.50.0 through 2.63.21 permit indefinite session persistence via expired JWT tokens when proxy authentication is configured with a non-default logout page, enabling an attacker who possesses any previously valid token to access protected routes and administrative endpoints beyond the token's expiration window. The authentication middleware intentionally waived JWT expiration under proxy-auth - since the proxy is expected to govern session lifetime - but failed to require the proxy to simultaneously assert the user's identity on each request, meaning a leaked or captured token could authenticate independently and indefinitely. No public exploit code has been identified at time of analysis; the fix commit and vendor security advisory are publicly available.
Authenticated remote code execution in UpSnap (a self-hosted Wake-on-LAN web app) before 5.4.0 lets any low-privileged user with device create/edit permission run arbitrary OS commands on the server. User-supplied device IP and MAC values are interpolated into the wake_cmd/shutdown_cmd shell templates and passed unsanitized to /bin/sh -c on Linux or cmd /C on Windows, giving full command execution in the app's process context. No public exploit was identified at time of analysis and it is not in CISA KEV, but the flaw is trivially triggerable at low attack complexity once an account exists; a companion setup-wizard flaw (GHSA-w4jr-728f-5jhq) can let an attacker seize the first superuser on un-provisioned public instances and chain into this RCE.
Arbitrary code execution is achievable on Windows endpoints running IBM i Access Client Solutions (ACS) 1.1.2.0 through 1.1.9.13 when the software is installed in all-users mode, because the installer leaves one or more configuration files world-writable. Any local user with standard (non-administrator) privileges can modify these files to inject code that executes under the security context of other users who subsequently launch the application. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the CVSS 7.8 High rating reflects the full confidentiality, integrity, and availability impact achievable once a local foothold exists.
Command injection in Shescape (npm shell-escaping library) versions below 2.1.14 and the 3.0.x line below 3.0.1 allows an attacker-controlled argument to break out of a parenthesized cmd.exe construct and inject arbitrary shell syntax on Windows. The flaw affects applications that call the escape or escapeAll APIs with shell set to cmd.exe (or shell:true when CMD is the default), because getEscapeFunction in src/internal/win/cmd.js failed to escape the ( and ) characters. A working proof-of-concept payload is published in the vendor advisory; there is no CISA KEV listing and no evidence of active exploitation at time of analysis.
Authentication bypass via spoofing in Dell Display and Peripheral Manager (DDPM) for Windows, versions prior to 2.3.0.17, enables local low-privileged attackers to escalate their privileges and execute arbitrary code on affected systems. The flaw (CWE-290) allows an attacker already present on the system to spoof an authenticated identity, circumventing DDPM's internal access controls. Dell has released a patched version (2.3.0.17) via advisory DSA-2026-320; no public exploit or CISA KEV listing has been identified at time of analysis.
Elevation of privilege and arbitrary code execution in Dell Display and Peripheral Manager (DDPM) for Windows, all versions prior to 2.3.0.17, is achievable by a low-privileged local attacker exploiting an authentication bypass by spoofing flaw. The CWE-284 root cause - improper access control - allows the attacker to circumvent DDPM's privilege verification, resulting in full confidentiality, integrity, and availability compromise on the affected host. No active exploitation has been confirmed by CISA KEV and no public exploit code has been identified at time of analysis; Dell has released the corrective patch in version 2.3.0.17 via advisory DSA-2026-320.
Elevation of privilege and arbitrary code execution in Dell Display and Peripheral Manager (DDPM) for Windows allows a low-privileged local attacker on affected systems to bypass access controls and run code at a higher privilege level. All DDPM versions prior to 2.3.0.17 are affected, as confirmed by Dell advisory DSA-2026-320. No public exploit code or CISA KEV listing has been identified at time of analysis, though tags indicate RCE and authentication bypass primitives are involved, consistent with the CWE-284 root cause.
