Authentication Bypass

Authentication bypass in the REST API of HPE Networking (Aruba) EdgeConnect SD-WAN Orchestrator lets an unauthenticated remote attacker circumvent web authentication and reach protected system functions, then view and modify sensitive configuration and network data. HPE (the reporting vendor) rates it CVSS 9.8 with a fully remote, no-privilege, no-interaction vector. No public exploit identified at time of analysis and it is not in CISA KEV, but the trivial exploitation profile on an internet-facing management plane makes it a high patch priority.

Property injection via the unauthenticated POST /api/v1/prediction/:id endpoint in Flowise allows remote unauthenticated attackers to overwrite session-critical fields (chatId, sessionId, chatHistory) and inject arbitrary values into the $flow.* template variable system of any public chatflow. Flowise versions up to and including 3.1.2 are affected; the fix was released in 3.1.3. Publicly available exploit code exists in the form of detailed curl-based proof-of-concept commands embedded in the public GitHub Security Advisory GHSA-6vh2-wg4h-4vwj, though active exploitation has not been confirmed by CISA KEV.

Unauthenticated arbitrary file read in Veeam ONE exposes sensitive server-side files to remote attackers without requiring any credentials, user interaction, or special configuration. The flaw, rooted in CWE-287 (Improper Authentication), enables a network-accessible authentication bypass that returns host filesystem content directly to the attacker. Exfiltrated files - likely including configuration data, database connection strings, or stored credentials - can then be used to escalate privileges locally, extending the impact beyond the initial confidentiality breach. No public exploit or active exploitation confirmed at time of analysis.

Unauthenticated Portal Administrator impersonation in Veeam Service Provider Console (VSPC) exposes the proxied appliance API to unauthorized access during a short race window that opens immediately after a legitimate administrator session is initiated. The flaw, rooted in CWE-306 (Missing Authentication for Critical Function), allows a network attacker without any credentials to issue API calls that the system processes with Portal Administrator privileges. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, though the managed service provider management role targeted makes this a significant concern for MSP environments.

Unauthenticated arbitrary file read in OpenCode Studio before 2.4.4 lets remote attackers pull other users' intermediate audio, video, and subtitle artifacts directly from the GET /api/tmp/:tmpFile and GET /api/music/:fileName endpoints, and delete any rendered video via the unauthenticated DELETE /api/short-video/:videoId endpoint. Reported by VulnCheck and rated CVSS 4.0 9.3, the flaw exposes both confidentiality and integrity of user job data with no login required. Publicly available exploit code exists, though there is no public exploit identified as being used in active attacks.

Authentication bypass in Qualcomm Snapdragon SoCs allows adjacent network attackers to exploit a cryptographic flaw during registration request processing, yielding high confidentiality and integrity compromise without requiring any privileges or user interaction. The flaw, rooted in CWE-306 (Missing Authentication for Critical Function), occurs when registration requests carry malformed or absent authentication parameters, causing the cryptographic subsystem to proceed without validating caller identity. No public exploit has been identified at time of analysis and Qualcomm has not confirmed active exploitation, but the CVSS 8.1 score and zero-privilege adjacent-network profile represent meaningful risk for devices on shared wireless segments.

Missing authorization on the `/api/v1/files` endpoint in Flowise allows any authenticated API key holder within an organization to enumerate and permanently delete files belonging to other workspaces. The route is guarded only by a plan-level feature gate (`feat:files`) with no `checkPermission` enforcement, meaning an API key scoped to an unrelated permission such as `tools:view` has full read and delete access to organization-wide file storage. Publicly available exploit code exists in the form of a fully reproducible curl-based proof-of-concept included in the GitHub Security Advisory GHSA-wp74-f5hh-5f3r. The fix in version 3.1.3 disables the endpoint entirely rather than adding proper authorization.

Unauthenticated SSRF with non-blind response reflection and OAuth2 secret exfiltration in Flowise affects all versions through 3.1.2. The OAuth2 token refresh endpoint is intentionally whitelisted from authentication but issues server-side HTTP POST requests to a credential-stored URL without SSRF controls, allowing any caller who knows a credential UUID to redirect the server to an attacker-controlled host and receive the full response body. A working proof-of-concept was confirmed against the flowiseai/flowise:latest container, with the exploit also exfiltrating client_secret and refresh_token values in the outbound POST body to the attacker server. No public exploit is independently confirmed as widespread, but the PoC is detailed and functional.

Privilege escalation in Liman MYS (HAVELSAN Inc.) versions 2.2.3 through pre-2.3.1 enables authenticated low-privilege users to gain administrator-level access via missing server-side authorization checks (CWE-862). The platform, a centralized Linux server management system used primarily in Turkish government and enterprise environments, fails to verify whether the requesting user has rights to perform privileged operations before executing them. No public exploit identified at time of analysis, but the CVSS 8.8 score with network vector and low privilege requirement makes this a high-priority patch target for any organization running the affected versions.

Unauthenticated device takeover of Puwell IP Cameras (firmware 2.x through 4.x) is possible by sending protocol-conforming packets to TCP port 23456 and abusing the unvalidated Session field in the vendor's proprietary control protocol. Remote attackers with no credentials can view live video, drive pan/tilt motors, activate audio, and reboot the camera. Publicly available exploit code exists (disclosed by VulnCheck), and the CVSS 4.0 base score of 9.3 reflects network-reachable, no-interaction access with high confidentiality, integrity, and availability impact; there is no CISA KEV listing indicating active exploitation at this time.

Missing authorization controls in HAVELSAN Liman MYS (versions 2.2.3 through before 2.3.1) allow a low-privileged authenticated user to access and invoke functionality that should be restricted to higher-privileged roles, resulting in full confidentiality, integrity, and availability compromise of the managed system. The flaw stems from CWE-862 - the application fails to enforce ACL checks before granting access to privileged operations, effectively allowing privilege escalation within the platform. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity and network accessibility make this straightforward to exploit by any authenticated user.

Silent authorization bypass in Eclipse Milo OPC UA server SDK versions 1.0.0-1.1.4 allows anonymous network clients to invoke protected methods, read role-permission metadata, and delete protected nodes. The defect is a missing field copy in `OpcUaServerConfig.copy()`: when servers construct their running configuration via this method, the configured `RoleMapper` is silently dropped, causing the `DefaultAccessController` to receive empty role ID lists for every session and skip all role-permission enforcement. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.

Authorization bypass in Eclipse Milo's OPC UA Call service (versions 1.0.0-1.1.4) permits unauthenticated or low-privileged OPC UA clients to invoke server-side methods they are explicitly denied access to. The server correctly computes per-method authorization for a mixed batch CallRequest but then dispatches the original unfiltered batch - including denied methods - to address-space handlers, rendering the authorization check effectively inert. No active exploitation is confirmed and no public exploit code has been identified, but the attack requires only standard OPC UA client tooling and zero authentication, making exploitation trivially accessible to any network-reachable client.

ASUSTOR Backup Plan (ABP) and EZSync (AES) background services run as NT AUTHORITY\SYSTEM and expose a file-based IPC channel whose AES encryption key is readable by standard users and recoverable via Windows DPAPI, allowing any authenticated local account to forge valid service requests. The services further fail to verify the identity of the requesting process and validate filesystem paths using an insufficient substring check, enabling directory traversal sequences to bypass path restrictions. A local attacker can chain these weaknesses to perform arbitrary file reads and writes as SYSTEM, achieving full local privilege escalation. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.

Unauthenticated arbitrary file access in the Easy Integration for Dropbox WordPress plugin before 2.2.0 lets remote attackers list, download, and upload files across the site's connected Dropbox account and harvest the connected-account and administrator email addresses. Several file-management AJAX actions are registered for logged-out users but skip authorization checks (CWE-862), turning the plugin into an open proxy to the linked cloud storage. Publicly available exploit code exists and a vendor patch is released, though EPSS estimates exploitation probability at only 0.14% (4th percentile).

Arbitrary code execution in NASA's core Flight System (cFS) v7.0.1 is possible through the Executive Services (ES) dynamic application start path, where improper access control lets an attacker plant a malicious shared object on target storage that is then loaded and run as a flight application. SSVC records a proof-of-concept exploit (publicly available exploit code exists) and rates technical impact as total with automatable exploitation, though EPSS is very low at 0.15% (5th percentile). The published NVD vector is CVSS 9.1 (AV:N), but the described mechanism - dropping a shared object onto storage - implies local write access is a genuine prerequisite.

Remote code execution in Microsoft Edge (Chromium-based) prior to version 151.0.4129.59 is achievable by an unauthenticated network attacker via a missing authorization check (CWE-862), requiring only that the victim interact with attacker-controlled content. The CVSS 3.1 score of 8.8 reflects high confidentiality, integrity, and availability impact with no privilege requirement, though user interaction is necessary. No active exploitation has been confirmed by CISA KEV, and SSVC currently rates exploitation status as none, suggesting this has not yet been weaponized at scale despite its serious technical impact classification.

Remote code execution in Microsoft Edge (Chromium-based) before 151.0.4129.59 allows a network attacker to run arbitrary code by exploiting a type-confusion condition (CWE-843) when a victim is lured to malicious web content. Because the CVSS scope is Changed (S:C), successful exploitation can escape the affected component and impact the broader system, making this a high-severity browser flaw. There is no public exploit identified at time of analysis and SSVC reports exploitation as 'none', but the total technical impact and 9.6 CVSS score warrant prompt patching.

Privilege escalation in Adobe Campaign Classic (ACC) stems from an incorrect authorization flaw (CWE-863) that lets an attacker gain elevated privileges without any user interaction. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) scores it 9.8 Critical, implying a network-reachable, low-complexity path to full compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, so exploitation is currently theoretical based on the vendor advisory.

Security feature bypass in Adobe Campaign Classic (ACC) exposes sensitive data to unauthenticated remote attackers via a violation of secure design principles (CWE-657). The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms that exploitation requires no credentials, no user interaction, and low attack complexity against any network-accessible ACC instance, yielding high confidentiality impact. No public exploit or CISA KEV listing has been identified at time of analysis; Adobe has published advisory APSB26-120 addressing this issue.

Prompt injection in Amazon Strands Agents Tools before 0.8.0 enables remote actors to execute arbitrary OS commands on the agent's host by crafting input that sets the shell tool's `non_interactive` parameter to `true`, silencing the human consent gate designed to require approval before running shell commands. The CVSS 4.0 vector (AV:N/PR:N) confirms no attacker authentication is required, though the agent must actively process the malicious prompt (UI:A) and the shell tool must be in use (AT:P). No public exploit code or CISA KEV listing has been identified at time of analysis.

Arbitrary command execution in Ouroboros (ouroboros-ai pip package, versions <= 0.42.0) is reachable when a developer runs `ooo` inside a malicious cloned repository, due to an incomplete denylist that left several execution-routing environment variable keys unblocked. The 0.39.0 fix for CVE-2026-47211 introduced `_UNTRUSTED_ENV_DENYLIST` but omitted keys spanning backend config-home roots, MCP bridge config, plugin trust roots, SSRF transport toggles, and capability override paths - all of which are auto-loaded from a project-directory `.env` at import with no review step. A separate code path additionally auto-loaded `./.ouroboros/mcp_servers.yaml` from the current working directory, enabling RCE with no `.env` file at all. No public exploit code has been identified at time of analysis, though the GHSA advisory provides sufficient technical specificity for independent derivation. Vendor-released patch 0.42.1 resolves both attack surfaces.

Authorization bypass in Apache NiFi 1.10.0 through 2.10.0 allows read-only authenticated users to submit Parameter Context validation requests that the system should restrict to write-privileged users. By supplying proposed parameter values in these requests, a low-privileged user can override active configuration and invoke component validation methods with attacker-controlled settings, potentially exposing sensitive configuration data or disrupting running data flow operations. No public exploit has been identified at time of analysis, but the CVSS 4.0 supplemental metrics flag the flaw as automatable (AU:Y) with concentrated value density (V:C), indicating scripted exploitation against high-value targets is plausible.

Privilege escalation in Dell Display and Peripheral Manager (DDPM Mac) versions prior to 2.3.0.1005 allows a low-privileged local attacker to invoke critical functions that lack authentication controls, gaining elevated system privileges. The root cause is CWE-306 (Missing Authentication for Critical Function), a well-understood vulnerability class in macOS privileged helper architectures. No public exploit or CISA KEV listing exists at time of analysis; Dell has released a patched version per advisory DSA-2026-319.

Elevation of privileges and arbitrary code execution in Dell Display and Peripheral Manager (DDPM) for macOS exposes endpoints running versions prior to 2.3.0.1005 to local privilege escalation attacks. An improper access control flaw (CWE-284) allows a low-privileged local account to bypass access controls enforced by DDPM, ultimately achieving arbitrary code execution with elevated rights. No public exploit has been identified at time of analysis, and no KEV listing exists, but the low attack complexity and complete impact across confidentiality, integrity, and availability make this a meaningful risk in environments where untrusted or shared local users exist on managed macOS endpoints.

OpenEMR through 8.2.0 exposes an OAuth2 password grant pathway that fully bypasses multi-factor authentication for any user with valid credentials, because the unauthenticated dynamic client registration endpoint allows an attacker to mint a first-party OAuth2 client and exchange legitimate credentials for an API access token without triggering the MFA challenge enforced on the normal web login interface. Any organization using OpenEMR's MFA controls to protect sensitive patient health information (PHI) is exposed: the control is structurally bypassed at the OAuth2 layer regardless of how MFA is configured in the web UI. A detailed public proof-of-concept writeup from JivaSecurity documents the full exploit flow, confirmed by VulnCheck advisory; no KEV listing has been observed at time of analysis.

Unauthenticated OAuth2 dynamic client registration in OpenEMR through 8.2.0 allows any network attacker to self-register a malicious OAuth2 client with system-level FHIR scopes by supplying a self-generated RSA keypair in the jwks field, bypassing all access controls on a critical endpoint. Once an OpenEMR administrator approves the registered client - a step that healthcare staff routinely perform for EHR interoperability integrations - the attacker authenticates via the client_credentials grant using a self-signed JWT and obtains access tokens covering all FHIR resources across every patient in the system. A publicly available proof-of-concept exploit and technical writeup from JivaSecurity confirm the attack chain; this CVE is not currently in CISA KEV but carries an 8.6 CVSS 4.0 score and exposes PHI at scale.

Administrative account takeover in Krayin CRM (Laravel CRM) 2.2.4 lets unauthenticated remote attackers overwrite the primary admin account by POSTing to the installer's admin-config-setup endpoint with an X-Requested-With: XMLHttpRequest header that defeats the CanInstall middleware redirect. Reported by VulnCheck with a publicly available exploit, it carries a 9.3 CVSS 4.0 and grants full control over all CRM data. There is no public exploit identified as actively exploited in CISA KEV, but working exploit code exists.

Signature verification bypass in XML::Sig (Perl) versions 0.29 through 0.71 allows remote unauthenticated attackers to submit arbitrary XML documents that are accepted as cryptographically valid without any digest or key check ever running. The verify() function unconditionally returns true after looping over all dsig:Signature elements, even when every iteration exited early via a skip path before cryptographic validation. No public exploit has been identified beyond the proof-of-concept test case embedded in the fix commit, and this vulnerability is not currently listed in the CISA KEV catalog.

Authentication bypass in Telenia Software TVox (versions 24.x ≤24.9.21 and 26.x ≤26.5.3) lets remote unauthenticated attackers reach every PHP script under the manager HTML directory by appending '/login_admin.php' to any target script's path. The flaw stems from set_env.php trusting the client-controllable PHP_SELF value when deciding whether to skip authentication. Publicly available exploit code exists (KarmaInSecurity KIS-2026-14, reported by VulnCheck), but there is no CISA KEV listing, so treat it as no public active exploitation confirmed despite a ready POC.

XML Signature Wrapping in Net::SAML2 before 0.86 allows any party holding a single valid IdP-signed assertion to authenticate as an arbitrary user against Perl applications that use this SAML SP library. Identity fields - NameID, attributes, SessionIndex, audience - are extracted via document-wide XPath queries selecting the first matching element in document order, not the element covered by the verified signature; an attacker who prepends an unsigned forged assertion to a Response containing their own legitimate signed assertion bypasses identity verification entirely while the signature check still passes. A vendor-released patch exists in version 0.86, and no public exploit has been identified at time of analysis.

Authentication bypass in Admidio's forum module before version 5.0.11 enables unauthenticated network-accessible attackers to read private forum topics and posts that administrators intended to restrict to logged-in members. The flaw stems from `modules/forum.php` failing to validate the login-only configuration state before serving content, meaning a direct HTTP request with read-only parameters is sufficient to circumvent the access gate. No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV, but the mechanistic simplicity of the bypass - a direct module access with no authentication - means exploitation requires minimal skill once a vulnerable, login-only-configured instance is located.

Information disclosure in SiYuan (a personal knowledge-management/note-taking application) before v3.7.3 lets anonymous readers or low-privilege publish RoleReader tokens read the full rendered content of documents that were explicitly marked publish-disabled. The getHeadingDeleteTransaction, getHeadingLevelTransaction, and getHeadingInsertTransaction endpoints return rendered block DOM without enforcing publish-access checks, so supplying a target heading block ID leaks restricted content. Reported by VulnCheck with a vendor patch available; no public exploit identified at time of analysis, and this is not listed in CISA KEV.

Broken access control in SiYuan versions before 3.7.3 lets publish-mode readers - including anonymous users when publish Basic Auth is disabled - retrieve the rendered content of publish-forbidden documents by calling the /api/ref/getBacklinkDoc and /api/ref/getBackmentionDoc endpoints directly with a target document ID. Although the corresponding backlink list endpoints correctly filter publish-forbidden documents, these two content endpoints are gated only by CheckAuth and omit the publish-access filter, exposing DOM content and a reference-existence oracle. Reported by VulnCheck; no public exploit identified at time of analysis and not listed in CISA KEV.

Authentication bypass in SiYuan (self-hosted knowledge-management/note-taking app) versions before v3.7.3 allows anonymous readers in publish mode to exfiltrate the full content of password-protected documents. While the primary getDoc endpoint enforces the publish-mode password, sibling content-returning endpoints (getHeadingChildrenDOM, the getHeading*Transaction family, and getBacklinkDoc) omit that check, so an attacker who harvests internal block IDs from reader-accessible endpoints can pull protected content directly. VulnCheck reported the issue and a vendor patch (v3.7.3) is available; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Authentication bypass in the Net::SAML2 Perl module before 0.86 lets an unauthenticated attacker log in as any user against Service Providers that accept EncryptedAssertions. The flaw stems from _verify_encrypted_assertion returning a decrypted assertion as 'verified' whenever it contains no dsig:Signature element, skipping both the signature and trust-anchor checks. Because an SP publishes its encryption certificate in SAML metadata, anyone can encrypt a forged unsigned assertion to it, wrap it in a samlp:Response, and post it to the assertion consumer service; no public exploit identified at time of analysis but the logic bug is trivially reproducible.

SAML authentication bypass in Net::SAML2 versions before 0.86 for Perl allows remote unauthenticated attackers to forge arbitrary SAML assertions against service providers that omit a trust anchor during library configuration. The flaw is in verify_xml, which exits early after validating the XML signature against the certificate embedded within the response itself - meaning an attacker who controls the response can supply their own self-signed certificate and sign any assertion they choose. No public exploit is identified at time of analysis, but the vulnerability is mechanically trivial to reproduce given that the vulnerable code path is fully documented in referenced MetaCPAN source files.

Authentication bypass in Check Point Security Management Server and Multi-Domain Security Management Server (MDS) lets an unauthenticated remote attacker with network access to Management services execute arbitrary commands and fully compromise the management system. It affects a broad range of releases (R80 through R82.10) including R81.20 and R82 running Jumbo Hotfix Accumulator takes at or below fixed thresholds. There is no public exploit identified at time of analysis; Check Point found the flaw internally and reports no indication of active exploitation despite the critical CVSS 4.0 score of 9.3.

Authorization bypass in Menulux Software Inc. Mobile App (all versions through the 12.05.2026 build) lets remote attackers manipulate a user-controlled key (an Insecure Direct Object Reference, CWE-639) to reach or alter resources belonging to other users, enabling a software integrity attack. TR-CERT rates it CVSS 9.8 with full CIA impact, though the primary documented effect is integrity tampering. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.

Authentication bypass in Tranquil IT Wapt Server before 2.6.1.17813 lets a remote unauthenticated attacker send a specially crafted packet to obtain a valid session token for a targeted account, yielding full account takeover of the endpoint-deployment console. Because Wapt Server orchestrates software installation across managed endpoints, a stolen operator/admin session effectively grants control over the fleet it manages. Rated CVSS 4.0 10.0 with subsequent-system impact; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Endress+Hauser FDI Package Library versions 1.00.00 through 2.01.00 exposes a CWE-427 (Uncontrolled Search Path Element) flaw in its iDTM FDI component, allowing a locally privileged attacker to activate the debug interface by dropping a crafted file into the application directory. Successful exploitation grants unauthorized access to connected industrial field devices, enabling data exfiltration, configuration manipulation, or operational disruption. No public exploit code has been identified at time of analysis, and exploitation is constrained by the requirement for elevated privileges and local host access - significantly limiting the realistic attack surface.

Account takeover in the ChamaWP WordPress plugin before 1.0.13 lets unauthenticated attackers reset the password of any user, including administrators, resulting in full site takeover. The flaw stems from improper validation of the password-reset request (CWE-862, missing authorization). Publicly available exploit code exists, though EPSS remains low (0.15%) and it is not listed in CISA KEV - no public in-the-wild exploitation confirmed at time of analysis.

Account takeover of the primary WordPress administrator affects the Simple Membership plugin in all versions before 4.7.8. Because the registration routine never checks whether user creation actually succeeded before treating the returned value as a valid user ID, an unauthenticated attacker can trigger a failed user creation and cause the plugin to overwrite the existing admin account's data - notably the email address - then seize the account through the standard password-reset flow. A vendor patch (4.7.8) and publicly available exploit details from WPScan exist, though EPSS remains low at 0.14% (4th percentile), indicating no measured mass exploitation yet.

Authentication bypass in the SoftMarket - Digital Marketplace WordPress plugin (versions through 1.0.0) lets remote unauthenticated attackers impersonate any verified user by supplying only that user's numeric ID to a flawed branch of the email-verification flow, resulting in full account takeover. Publicly available exploit code exists (published by WPScan), and the CVSS 3.1 score of 9.1 reflects high confidentiality and integrity impact with no privileges or user interaction required. Despite the critical rating, the EPSS probability is low (0.19%, 9th percentile) and there is no evidence of active exploitation.

Local privilege escalation in MediaTek's Bluetooth driver affects six Wi-Fi/Bluetooth combo chipsets (MT7902, MT7920, MT7921, MT7922, MT7925, MT7927) due to a missing permission check (CWE-862) that allows a standard user-level process to invoke restricted driver operations. An attacker with low-privilege local access can fully compromise confidentiality, integrity, and availability of the affected system without any user interaction. No public exploit identified at time of analysis; EPSS at 0.15% (5th percentile) and SSVC exploitation status of 'none' confirm negligible current exploitation activity.

Privilege escalation in MediaTek's Android Telephony component enables any locally-installed application - regardless of its declared Android permissions - to invoke protected telephony operations by exploiting a missing authorization check (CWE-862). The flaw affects 35 MediaTek chipsets spanning the Helio and Dimensity families and yields high confidentiality and integrity impact over telephony functions such as call management and SMS routing. No public exploit has been identified and EPSS of 0.15% (5th percentile) indicates negligible current exploitation activity, though the zero-privilege-required nature of local exploitation lowers the attacker bar once device access is established.

Certificate name-constraint bypass in Bouncy Castle for Java allows a crafted certificate to escape X.509 permitted/excluded subtree restrictions by appending a trailing dot to an rfc822Name (email) or URI host, or by prepending RDNs ahead of a permitted directoryName. Any relying party using BC's PKIXNameConstraintValidator (via CertPathValidator/CertPathBuilder) to enforce name constraints can be tricked into trusting an identity a constrained CA was never authorized to issue, enabling impersonation and effective authentication bypass. There is no public exploit identified at time of analysis, but the vendor rates it 9.3 (Critical) and a fix is available.

Path traversal in the DS_SetDestPathCmd() function of NASA Core Flight System (cFS) v7.0.1 enables remote unauthenticated attackers to bypass access controls and read sensitive system components by supplying a crafted destination path string. The DS (Data Storage) application fails to properly sanitize or restrict path values passed via command, violating the intended access control boundary between storage destinations and protected system components. A proof-of-concept exists per SSVC data, and exploitation is assessed as automatable, though real-world risk is tempered by the specialized aerospace deployment context and a very low EPSS score of 0.14% (4th percentile).

Incorrect access control in NASA Core Flight System (cFS) v7.0.1 permits unauthenticated remote attackers to manipulate the telemetry subscription table by sending arbitrary TO_LAB (Telemetry Output Lab) add and remove subscription commands. Low-index subscriptions can be silently removed and new data streams injected, threatening the integrity of telemetry routing on ground-connected flight software deployments. No public exploit has been identified at time of analysis, and the EPSS score of 0.14% (4th percentile) indicates very low observed exploitation activity, though the complete absence of authentication on a command interface is a structurally severe design flaw.

Authentication bypass and account takeover in N-able N-central through version 2026.3.1 stem from an incomplete remediation of CVE-2026-18556, leaving an alternate authentication path exploitable by unauthenticated remote attackers. The vendor's CVSS 4.0 submission includes E:A (Attacked), indicating active exploitation is occurring against this incomplete patch. Despite high attack complexity (AC:H), the absence of privilege requirements and the high-value nature of RMM platforms - which provide lateral movement to thousands of managed endpoints - makes this a critical priority for MSP operators.

Cross-tenant information disclosure in the self-hosted task manager Vikunja (0.24.0 through 2.3.0) lets a holder of any project share link read kanban bucket records - bucket titles and the full created_by user object (username, name, id) - belonging to other tenants' project views, because the task-collection endpoint loads the view from the attacker-controlled URL path without re-authorizing it. The same missing pre-authorization check yields a project/view-ID existence oracle (404 vs non-404) usable by link shares and ordinary authenticated users. No public exploit identified at time of analysis; fixed in 2.4.0.

Principal type confusion in Vikunja (versions 0.22.0-2.3.0) allows an authenticated low-privilege attacker to fully control any target user's API token management by exploiting a numeric ID collision between the independent link-share and user ID sequences. The `/api/v1/tokens` endpoints resolve the caller identity exclusively via the generic `web.Auth.GetID()` interface without validating whether the authenticated principal is a user or a link-share, meaning a link-share JWT whose integer ID equals a victim's user ID is accepted as that user's credential. No CISA KEV listing and no public exploit code have been identified at time of analysis, but successful exploitation yields the ability to mint new API tokens under a victim's identity with attacker-chosen permission scopes, constituting a functional account takeover at the API level.

Privilege escalation in ArcadeDB before 26.7.3 allows any authenticated MCP user to fully bypass the database authorization framework. The MCP HTTP transport layer fails to bind the authenticated principal into the engine's permission context, causing all access control checks to silently resolve as no-ops regardless of the user's actual role. Affected users can perform arbitrary DDL, schema mutations, unrestricted database writes, and execute arbitrary JavaScript via the query tool - effectively gaining root-level database access from a low-privileged account. No public exploit has been identified at time of analysis and this CVE is not listed in CISA KEV, though the impact is severe for any deployment with MCP transport enabled.

Simply Schedule Appointments WordPress plugin before 1.6.12.6 exposes all site appointment records to unauthenticated users through a bulk operation endpoint lacking object-level authorization, enabling mass personal data (PII) disclosure across the entire WordPress installation. On premium editions, the same unauthenticated path allows permanent deletion of all appointment records, adding a destructive integrity and availability impact not reflected in the published CVSS score. A public proof-of-concept exists per WPScan, and the SSVC framework rates this as automatable with no active CISA KEV listing; EPSS at 0.19% suggests limited observed exploitation to date but does not negate the ease of scripted mass harvesting.

Unauthorized media file disclosure in the Product Attachment for WooCommerce WordPress plugin (all versions before 2.3.3) allows any unauthenticated internet user to download arbitrary WordPress media library files by enumerating sequential numeric attachment IDs. The plugin's file-streaming endpoint performs no authorization check whatsoever, exposing private or deliberately unlinked uploads - such as internal documents, confidential product specifications, or draft media - to the public. A publicly available proof-of-concept exists per WPScan, though EPSS sits at 0.15% (5th percentile), indicating low observed exploitation rates at time of analysis despite easy weaponization.

Complete authentication bypass in the login-social WordPress plugin (≤1.0.4) enables unauthenticated remote attackers to reset any user's password without a valid reset key and to forge login sessions using unverified third-party identity data, giving attackers full administrator access and site takeover capability. Any WordPress site running this plugin is exposed regardless of configuration, as both failures reside in the plugin's core authentication flows. A publicly available exploit exists per WPScan; EPSS sits at 0.19% (9th percentile), suggesting exploitation is targeted rather than widespread at this time, though the public PoC lowers the technical barrier considerably.

Account takeover via unauthenticated password reset in the Lenxel WP WordPress theme (all versions through 1.0.31) allows any unauthenticated remote attacker to seize control of any WordPress account, including site administrators, by submitting a crafted reset request without owning or being authorized for the target account. The theme's reset action validates only a WordPress CSRF nonce - obtainable by any visitor loading the reset page - while performing no ownership or authorization check against the account being reset. No confirmed active exploitation (not in CISA KEV), though a public POC exists via WPScan and SSVC rates the technical impact as total; EPSS remains very low at 0.12% (2nd percentile), consistent with the niche theme footprint.

Unauthenticated API abuse in the AI ChatBot for WooCommerce WordPress plugin (all versions before 4.8.4) permits any remote visitor to trigger a backend AJAX action with no authorization check or nonce validation, causing the plugin to forward requests to the site owner's stored third-party AI API credentials - generating charges billed directly to the owner's account. A publicly available exploit exists per WPScan, though EPSS sits at 0.15% (5th percentile), indicating limited current automated exploitation; this CVE is not listed in the CISA KEV catalog. When the plugin's optional knowledge-base indexing feature is enabled, the same unprotected endpoint additionally exposes indexed site content to unauthenticated retrieval, introducing a confidentiality dimension alongside the financial abuse risk.

Authentication bypass in the SMS Alert WordPress plugin before 3.9.8 allows unauthenticated remote attackers to log in as any registered user - including site administrators - by exploiting broken OTP session binding. The plugin marks a session as 'mobile verified' after an attacker validates an OTP to their own phone, then naively trusts a separately supplied, attacker-controlled phone number to resolve and authenticate the target account. A public proof-of-concept is available via WPScan; while EPSS remains low at 0.15% (5th percentile), the combination of administrative account takeover potential and available exploit code makes this a high-priority patch for affected WordPress deployments.

Missing capability check on a WordPress AJAX action in Five Star Restaurant Reservations before 2.7.23 permits any user holding the plugin's lowest booking-management role to reset the site's configured booking notification rules - a setting they are explicitly barred from accessing through the UI. Notably, the provided CVSS vector (PR:N, C:H) conflicts materially with the description, which requires an authenticated role and describes an integrity-only impact; defenders should not rely on the published score at face value. A publicly available exploit exists via WPScan, though EPSS at 0.13% (3rd percentile) indicates no meaningful opportunistic exploitation has been observed.

Privilege escalation in Red Hat Build of Keycloak's user creation component exposes environments running Fine-Grained Admin Permissions V2 (FGAP V2) to unauthorized group assignment by scoped sub-administrators. A sub-admin holding only user-create permissions can bypass group-level authorization checks and enroll newly created users into any group - including privileged or sensitive ones - well beyond the sub-admin's delegated scope. SSVC rates technical impact as total and no public exploit has been identified, though the EPSS score of 0.24% (15th percentile) and SSVC exploitation status of 'none' indicate low immediate exploitation likelihood.

Authentication bypass in the WooCommerce - Social Login plugin for WordPress (all versions up to and including 2.8.7) lets unauthenticated attackers log in as any existing user, including administrators, by forging an Apple id_token containing the victim's email address. The Apple login handler base64-decodes the JWT payload but never verifies the token signature against Apple's public keys nor validates the issuer, audience, or expiry claims, and the nonce needed to trigger the flow is publicly leaked to anonymous visitors. Reported by Wordfence and rated CVSS 9.8; no public exploit identified at time of analysis.

Authentication bypass in N-able N-central through version 2026.1 allows unauthenticated remote attackers to circumvent authentication controls via an alternate path or channel (CWE-288), resulting in high confidentiality impact against the vulnerable system. The CVSS 4.0 vector (AV:N/AC:H/PR:N/UI:N/VC:H) indicates exploitation requires elevated attack complexity but no credentials, suggesting a non-trivial bypass technique such as direct access to an unauthenticated API endpoint or alternate URL path that bypasses the primary authentication gateway. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.

Route-level authentication bypass in Traefik v3.7.0-v3.7.7 allows unauthenticated remote attackers to reach backend endpoints protected by BasicAuth, DigestAuth, or ForwardAuth by exploiting unnormalized dot-segment paths generated by the Kubernetes Ingress NGINX provider's RewriteTarget middleware. When an Ingress path regex captures attacker-controlled text without requiring a path separator (e.g., /api(.*) rewriting to /$1), a crafted request such as /api../admin is rewritten to /../admin and forwarded to a backend that resolves it to /admin - a path secured on a separate Traefik router - entirely bypassing route-level access controls. No public exploit has been identified at time of analysis; a vendor patch is available in v3.7.8.

Permission bypass in ArcadeDB before 26.7.2 allows authenticated read-only users to execute privileged schema-mutation SQL operations that should require the UPDATE_SCHEMA permission. A user holding only a read-only API token can submit ALTER TYPE ... CUSTOM or ALTER TYPE ... BUCKETSELECTIONSTRATEGY statements to the HTTP command endpoint, invoking setCustomValue and setBucketSelectionStrategy on LocalDocumentType without any permission enforcement. The consequence is unauthorized corruption of schema metadata and bucket-selection strategy, potentially disrupting record routing and data integrity across the database. No public exploit has been identified at time of analysis and this CVE is not listed in CISA KEV; a vendor-released patch is available in version 26.7.2.

Cross-organization billing authorization bypass in @better-auth/stripe allows authenticated members of multiple organizations to perform subscription actions - including plan cancellation, plan changes, restoration, and billing portal access - against organizations whose billing they should not control. The root cause is a parameter source mismatch: middleware validates the organization ID from the request query string, while the route handler resolves it from the request body and falls back to the caller's active session organization, enabling an attacker to pass authorization for one org while the action executes against another. No public exploit has been identified and no CISA KEV listing exists, but the CVSS 4.0 score of 7.1 reflects a network-accessible, low-complexity attack path with high integrity impact on billing state.

Scripting authorization bypass in ArcadeDB before 26.7.2 lets any authenticated database user - including read-only roles - run sandboxed JavaScript by submitting a SQL 'DEFINE FUNCTION ... LANGUAGE js' statement, defeating a control that was supposed to restrict scripting to security administrators. The prior GHSA-48qw-824m-86pr hardening added a UPDATE_SECURITY permission gate to the polyglot engine, but the SQL route to JavaScript never invokes it, so low-privilege users regain the very capability the gate was meant to remove. Reported by VulnCheck; the vendor advisory publicly documents a complete two-request exploitation recipe, and the vendor scores it CVSS 4.0 9.3 (Critical), though the runtime sandbox meaningfully limits real-world impact.

Two-factor authentication bypass in better-auth (npm) before version 1.4.9 allows network-accessible attackers holding valid primary credentials to access protected application routes without completing second-factor verification. The flaw stems from premature session caching: when session.cookieCache is enabled alongside 2FA, the session generated after primary sign-in is stored as fully valid before the second factor is checked, and subsequent lookups return the cached authenticated session without re-evaluating the 2FA requirement. No public exploit code or CISA KEV listing has been identified at time of analysis, but the attack is conceptually straightforward for any user or attacker who already possesses a valid username and password.

Multiple authentication bypass vulnerabilities in @better-auth/sso before version 1.6.21 enable low-privileged attackers to take over arbitrary user accounts via four distinct attack paths: domain verification parsing mismatches, orphaned SSO provider accounts, unbound SAML assertions, and reflected XSS on logout endpoints. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) with VC:H/VI:H confirms high confidentiality and integrity impact with no availability loss. No public exploit has been identified at time of analysis and no CISA KEV listing exists, but the multiplicity of bypass vectors significantly raises the probability that any given deployment is exploitable through at least one path.

Pre-account hijacking in better-auth (npm) allows a remote attacker to gain persistent, password-based access to any victim account on applications that combine open email/password registration with the magic-link or email-OTP passwordless plugins. The attacker plants a password on the victim's email address before the legitimate owner ever signs in; when the owner later authenticates via the passwordless flow, the library verifies the account without clearing the pre-existing password or revoking pre-existing sessions, leaving the attacker's credentials valid. No public exploit identified at time of analysis, but the attack is mechanically trivial and requires only the ability to register an account - no special tooling, credentials, or network position needed.

TLS server certificate purpose validation bypass in FreeRDP before 3.29.0 allows a trusted, hostname-matching certificate issued only for client authentication (clientAuth EKU) to be accepted as a valid RDP server certificate. This weakens the trust model in environments that rely on Extended Key Usage separation between client and server certificates, enabling an attacker who can present such a certificate to impersonate the RDP server. Reported by VulnCheck with a vendor patch available; no public exploit identified at time of analysis and not listed in CISA KEV.

Authorization bypass in @better-auth/scim versions 1.5.0 through 1.7.0-beta.3 allows any authenticated user to fully take over another user's non-organization SCIM provider by exploiting a missing ownership binding. The root flaw (CWE-639) means provider rows are created without a userId by default, causing the access check to pass silently for any caller. An attacker with a valid session can regenerate a victim's SCIM bearer token, invalidating the legitimate token and authenticating to SCIM API routes with the attacker-controlled credential. No public exploit or KEV listing is confirmed at time of analysis, but the CVSS 4.0 score of 8.7 reflects the low exploitation complexity for any authenticated user.

TLS server-identity verification bypass in FreeRDP 3.x (all versions <= 3.28.0) lets a network attacker positioned between an RDP client and server defeat certificate hostname validation. Because tls_verify_certificate()/tls_match_hostname()/x509_utils_get_dns_names() perform custom Common Name and DNS SAN string matching instead of OpenSSL's length-aware identity APIs, NUL-truncated SAN values, CN acceptance despite non-matching SANs, and IP-literal matching without iPAddress SAN comparison all pass verification. Reported by VulnCheck with a vendor patch (3.29.0); no public exploit identified at time of analysis and it is not on CISA KEV.

Privilege-escalating account takeover in the @better-auth/scim plugin (versions 1.4.0-beta.27 through 1.6.21 and 1.7.0-beta.0 through 1.7.0-beta.9) lets an authenticated low-privileged user mint a SCIM bearer token whose provider ID collides with an existing SSO, SAML, OIDC, generic OAuth, or social provider namespace, causing SCIM user routes to operate on global accounts the token never provisioned. Attackers can list, read, rewrite (email/profile with no uniqueness check), and delete arbitrary Better Auth users and sessions, yielding full account takeover and unauthorized deprovisioning. No public exploit is identified at time of analysis and it is not in CISA KEV, but the vendor's detailed root-cause writeup makes exploitation straightforward once the plugin is enabled.

Cross-database authorization bypass (IDOR) in ArcadeDB before 26.7.2 lets attackers read and write any database on the server by supplying an arbitrary {database} parameter to the time series (/ts/*), batch, Prometheus, and Grafana HTTP handlers. Roughly 14 endpoints resolve the target database and call getDatabase(...) without invoking canAccessToDatabase(...), so a caller scoped to one database (or, per the code, potentially an anonymous request) gains full read/write over databases they were never granted. Reported by VulnCheck with a vendor patch (26.7.2) available; the GHSA advisory publishes concrete exploitation requests, and while EPSS is not provided the CVSS 4.0 base score is 9.3 (Critical). This is not in CISA KEV.

Authentication bypass in the Single Sign On For TNG WordPress plugin (all versions through 2.0.0) lets unauthenticated attackers reset the password of any account, including administrators, resulting in full site takeover. The `ssoprocess_ajax()` handler is exposed via `wp_ajax_nopriv_` and performs a password reset on any email-identified account with no ownership token or capability check, guarded only by a nonce that the plugin itself publicly broadcasts to logged-out visitors. Reported by Wordfence with a maximal CVSS of 9.8; no public exploit has been identified at time of analysis.

Cross-Site Request Forgery in AI Engine plugin (all versions ≤ 3.6.5) enables unauthenticated attackers to create new WordPress administrator accounts by tricking a logged-in site admin into clicking a crafted link. The attack exploits missing nonce validation on the `reauth_for_authorize` function in `labs/mcp-oauth.php`, combined with WordPress's built-in `?_method=POST` method-override feature to convert an innocuous-looking GET navigation request into an authenticated POST to the REST `/users` endpoint - no attacker account required. No public exploit has been identified at time of analysis, but the attack primitive is straightforward and the impact (full site takeover) is severe.

Account takeover in the Login & Register Forms WordPress plugin (versions before 3.2.5) enables unauthenticated attackers to brute-force password-reset verification codes by bypassing the plugin's rate-limit control. The rate limiter and code storage are both keyed on a client-supplied value, meaning an attacker can arbitrarily reset their attempt counter and exhaust the verification code space, resulting in full compromise of any account - including site administrators - on affected WordPress installations. A publicly available proof-of-concept exploit exists; no CISA KEV confirmation has been issued, but the admin-takeover impact makes this a high-priority patch for any site running the affected configuration.

Password reset link host poisoning in DynamicKit for Elementor WordPress plugin (versions before 1.0.3) enables unauthenticated attackers to redirect victims' password reset emails to an attacker-controlled domain, carrying a valid reset key issued by the legitimate WordPress site. When the victim clicks the link, the attacker captures the reset token and achieves full account takeover. A publicly available exploit exists via WPScan, though EPSS sits at just 0.14% (4th percentile), indicating limited observed exploitation despite the severity rating and POC availability.

Password reset authentication bypass in the Chat On Desk Order Notifications WordPress plugin (versions before 1.0.9) allows unauthenticated remote attackers to take over arbitrary user accounts, including administrators, by submitting a new password without completing OTP verification. Exploitation is conditional on the SMS one-time-password reset feature being active on the target site. A publicly available proof-of-concept exists per WPScan, though EPSS sits at 0.14% (4th percentile) and SSVC rates exploitation status as 'none,' suggesting currently limited attacker uptake despite disclosed exploit code. No confirmed active exploitation (CISA KEV) at time of analysis.

Unauthorized arbitrary file deletion in the FormGent WordPress plugin (versions up to and including 1.9.2) allows unauthenticated remote attackers to delete files via the /wp-json/formgent/responses/attachments REST endpoint, which was registered with no authentication middleware. On Linux hosts where the wp-content/uploads/formgent directory has not yet been created (the default post-install state), path-traversal protections can be bypassed to delete files outside the intended directory, including wp-config.php - enabling full site takeover through the fresh-install re-configuration flow. No public exploit identified at time of analysis and the flaw is not listed in CISA KEV, but the CVSS score is 9.1 (Critical).

Session hijacking in Coturn TURN/STUN server prior to 4.15.0 allows an authenticated attacker who obtains a victim's MOBILITY-TICKET to seize the victim's TURN allocation, intercepting and injecting relayed traffic while exhausting the victim's quota. The flaw resides in the --mobility (MICE, RFC 8016) session-resume code path in handle_turn_refresh: the server locates the victim allocation via an attacker-controlled mobile ID and then validates the REFRESH against the attacker's own credentials rather than the allocation owner's, because the hmackey_set flag set during the attacker's own prior authentication is never cleared for long-term-credential sessions and silently suppresses the credential-copy step. No public exploit code or CISA KEV listing is identified at time of analysis; CVSS AC:H and PR:L reflect that exploitation requires both a legitimate authenticated session and possession of the victim's MOBILITY-TICKET.

Exposure of a default-credentialed PostgreSQL database in the VPS.org one-click Supabase template allows remote attackers to connect directly to the database on 0.0.0.0:5432 using the well-known default password 'postgres', gaining full read/write access. The flaw stems from insecure default initialization combined with Docker's iptables rules overriding host UFW firewall policy, so operators who believe UFW protects the port are silently exposed. No public exploit has been identified at time of analysis, and EPSS is low (0.14%, 4th percentile), but SSVC rates the technical impact as total and exploitation as automatable.

Deploy-time policy bypass in Red Hat Advanced Cluster Security for Kubernetes 4 lets a user with Kubernetes Deployment-create permission spoof workload identity by setting the openshift.io/encoded-deployment-config label to "null", forcing ACS to record the workload with empty UID, name and labels and a "default" namespace. This evades ACS deploy-time policy detection and enforcement visibility and corrupts Central's persistence, violation reporting and compliance correlation. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Hard-coded credential exposure in Andritz HIPASE-250 (formerly 250 SCALA) engineering workstations lets an adjacent-network attacker log in over VNC using a fixed x11vnc password baked into the provisioning script. Because every workstation provisioned with that script shares the identical credential, one leaked or reverse-engineered password unlocks remote graphical control of all affected units across a site. Rated CVSS 8.1; no public exploit identified at time of analysis and not listed in CISA KEV.

Information disclosure in ANDRITZ HIPASE-250 (formerly 250 SCALA) lets any unauthenticated attacker with network reachability query the device's data and configuration endpoint, exposing live process values and full server configuration. The flaw stems from the default configuration shipping with no authentication and permissive CORS on every response, so no credentials or user interaction are required. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Token exchange in Keycloak bypasses Google Workspace domain allowlist restrictions, enabling any valid Google account holder - regardless of their domain - to swap a Google OAuth token for a Keycloak realm token and gain unauthorized access. Affected deployments are those specifically configured to restrict Google-based logins to approved Workspace domains while also having token exchange enabled; both conditions must be present. No public exploit code has been identified at time of analysis, and EPSS sits at 0.20% (10th percentile), consistent with SSVC's exploitation status of 'none', though SSVC rates technical impact as 'total' given that successful exploitation delivers full realm access.

Tenant-restriction bypass in Keycloak's Microsoft identity provider integration allows attackers holding any valid Microsoft OAuth token - even from a completely unrelated Azure AD organization - to authenticate into a Keycloak realm via the token exchange feature. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, and Red Hat JBoss EAP Expansion Pack. With CVSS PR:L reflecting the need for a valid Microsoft credential (trivially obtained by registering a free Azure tenant), successful exploitation grants high confidentiality and integrity impact within the realm. No public exploit or active exploitation has been identified at time of analysis; EPSS sits at 0.19% (9th percentile), consistent with SSVC exploitation=none.

Administrator account takeover in the ShopMonitor.io WordPress plugin before 1.2.0 allows unauthenticated attackers to hijack outgoing emails. The plugin's email-rerouting test mode is gated only by a trusted-source check that can be satisfied with client-supplied request headers, so an attacker can redirect the WordPress administrator password-reset email to an address they control and seize the admin account. Rated CVSS 9.8 with publicly available exploit code; EPSS is low (0.14%, 4th percentile), and it is not listed in CISA KEV - no public exploit identified as actively used at time of analysis, though POC exists.

Two-factor authentication is completely bypassable in the miniOrange 2FA WordPress plugin before version 6.2.6, enabling an attacker who already holds a victim's password to authenticate as that user - including site administrators - by supplying a self-referential OTP value the plugin incorrectly validates against an attacker-controlled parameter rather than the user's stored secret. All WordPress installations running the affected plugin versions are exposed to full account takeover with no prior plugin privileges required. A publicly available proof-of-concept exists per WPScan; however, EPSS probability stands at 0.19% (9th percentile) and SSVC exploitation status is classified as 'none,' indicating no confirmed mass exploitation at time of analysis.
