Authentication Bypass

Remote root shell access via hardcoded telnet backdoor in D-Link DIR-600L Hardware Revision A1 allows network-adjacent attackers to authenticate with publicly known credentials ('Alphanetworks' / 'wrgn35_dlwbr_dir600l') and obtain full administrative control. The backdoor telnet daemon launches automatically at boot with static credentials stored in /etc/alpha_config/image_sign. The device is End-of-Life with no patches forthcoming, creating permanent exposure for deployed units. EPSS data not available; no CISA KEV listing identified, though the trivial exploitation complexity (CVSS AC:L, PR:N) and public disclosure make exploitation highly likely once details are disseminated.

D-Link DIR-600L Hardware Revision B1 routers expose a hardcoded telnet backdoor granting unauthenticated remote attackers root shell access via static credentials ('Alphanetworks' / 'wrgn61_dlwbr_dir600L'). The vulnerability affects End-of-Life devices that will never receive patches, making permanent network isolation or replacement the only remediation options. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) and publicly documented credentials, this represents critical risk for any exposed device, though exploitation requires local network access despite the 'Network' attack vector classification.

Hardcoded telnet backdoor in D-Link DIR-605L Hardware Revision B2 firmware enables unauthenticated root access for remote attackers on the local network using static credentials 'Alphanetworks:wrgn76_dlwbr_dir605L'. The telnet daemon starts automatically at boot, validating credentials via strcmp() against hardcoded values in /etc/alpha_config/image_sign, granting complete administrative control to anyone who knows the password. This End-of-Life device will receive no security patches. EPSS data not available; no CISA KEV listing identified at time of analysis, suggesting targeted disclosure rather than widespread exploitation campaigns.

Hardcoded credentials in D-Link DIR-605L Hardware Revision A1 firmware grant root-level telnet access to unauthenticated attackers on adjacent networks. The telnet daemon automatically starts at boot with username 'Alphanetworks' and static password 'wrgn35_dlwbr_dir605l', enabling complete device takeover including network traffic interception, configuration modification, and pivot attacks against internal networks. This End-of-Life product will receive no vendor patch, requiring immediate device replacement. CVSS score of 8.8 reflects high impact across confidentiality, integrity, and availability, with adjacent network attack vector reducing but not eliminating risk for home and small office deployments.

Authentication bypass in Red Hat Ansible Automation Platform 2.6 allows authenticated attackers to hijack arbitrary user accounts, including administrator accounts, via email-based identity provider linking manipulation. The AAP gateway's user auto-link feature matches external IDP identities to existing accounts by email without ownership verification, enabling account takeover when an attacker controls an IDP account with a victim's email address. Red Hat has released patch RHSA-2026:13508. EPSS and KEV data not provided, but the low attack complexity (AC:L) and high confidentiality/integrity impact make this a critical authentication control failure requiring immediate remediation in environments using external identity providers.

Tenant administrators in Comet Backup 20.11.0 through 26.1.1 and 26.2.1 can impersonate any end-user account across different tenants on the same server through an insecure direct object reference (IDOR) in an API endpoint. The vulnerability enables complete cross-tenant authentication bypass in multi-tenant deployments, allowing unauthorized access to backup data, configurations, and operations of arbitrary users. With CVSS 9.9 (Critical) rating and network-accessible exploitation requiring no privileges, this represents an immediate risk to managed service providers and multi-tenant Comet Backup installations, though no active exploitation has been confirmed via CISA KEV at time of analysis.

Authenticated vendors with low-level privileges can delete arbitrary WordPress users, including site administrators, via Insecure Direct Object Reference in WCFM - Frontend Manager for WooCommerce plugin versions up to 6.7.25. The vulnerability resides in the 'wcfm_delete_wcfm_customer' function which fails to validate user-controlled 'customerid' parameters, allowing privilege escalation through unauthorized user deletion. Patch available in version 6.7.26 per Trac changeset 3483695. No public exploit code or active exploitation confirmed at time of analysis, though CVSS 8.1 (High) reflects significant real-world impact if exploited by malicious vendors on WooCommerce marketplaces.

Authenticated attackers with Subscriber-level access can disrupt all Stripe payment processing in Paid Memberships Pro for WordPress versions up to 3.6.5 by deleting, creating, or rebuilding webhook configurations. Missing capability checks on three AJAX handlers (pmpro_stripe_create_webhook, pmpro_stripe_delete_webhook, pmpro_stripe_rebuild_webhook) allow low-privilege users to break subscription renewals, cancellation handling, and failed payment management for the entire site. Patch available in PR #3615 implementing proper authorization checks requiring manage_options or pmpro_paymentsettings capabilities plus nonce validation. EPSS data not provided; no CISA KEV listing indicates no confirmed active exploitation at time of analysis.

Insecure Direct Object Reference in Zyosoft School App allows authenticated remote attackers to escalate privileges horizontally by manipulating object identifiers in API requests, enabling unauthorized read and write access to other users' personal data including student records, grades, and account information. The vulnerability requires only low-level authentication (PR:L) with no user interaction and poses high confidentiality and integrity risk to multi-tenant educational data. EPSS and KEV data not available; exploitation complexity is low (AC:L) making this accessible to moderately skilled attackers once credentials are obtained.

Authentication bypass in User Verification by PickPlugins for WordPress allows remote unauthenticated attackers to log in as any user with a verified email - including administrators - by submitting the string 'true' as the OTP code. The vulnerability stems from a loose PHP comparison operator (==) in the OTP validation logic, which treats the boolean true as equal to any non-zero numeric OTP value. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) and EPSS data unavailable, this represents complete system compromise risk for WordPress sites running vulnerable versions (≤2.0.46). Fixed in version 2.0.47 per Wordfence advisory and WordPress plugin repository changeset 3519113.

Missing capability check in WP Mail Gateway plugin for WordPress (versions ≤1.8) allows authenticated attackers with Subscriber-level privileges to modify SMTP settings via the wmg_save_provider_config AJAX action, enabling mail redirection. Attackers exploit this by redirecting password reset emails to attacker-controlled servers, then using intercepted credentials to escalate privileges to Administrator. CVSS 8.8 (High) reflects the severe impact despite requiring initial low-level authentication. No active exploitation confirmed via CISA KEV, but Wordfence reporting indicates discovery by security researchers and likely inclusion in their threat intelligence feeds.

Integrity verification bypass in Linux kernel crypto subsystem's Kerberos 5 encryption module allows remote unauthenticated attackers to bypass cryptographic hash checks when asynchronous decryption completes. The vulnerability stems from incorrect callback chaining that skips krb5enc_dispatch_decrypt_hash() verification entirely during async operations. Exploitation likelihood is low (EPSS 2%, percentile 4%) despite high CVSS severity, though EUVD classifies this as an authentication bypass affecting Linux 6.15+ with patches available for stable branches 6.18.25, 7.0.2, and mainline 7.1-rc1.

Time-of-check-time-of-use (TOCTOU) race condition in Linux kernel's TPACKET transmission path allows local authenticated attackers with low privileges to bypass vnet_hdr validation checks and potentially achieve privilege escalation, code execution, or system compromise. The vulnerability affects packet socket implementations when PACKET_VNET_HDR is enabled, where concurrent userspace threads can modify mmap'd ring buffer data between kernel validation and use. Vendor-released patches are available for stable kernel branches (6.6.136, 6.12.84, 7.0.2, 7.1-rc1). EPSS score of 0.02% (5th percentile) indicates low observed exploitation probability, and no active exploitation is confirmed (not in CISA KEV), though the high CVSS 7.8 reflects significant local impact potential.

Race condition in Linux kernel ATM LEC driver allows local attackers with low privileges to trigger use-after-free memory corruption in sock_def_readable(), potentially achieving arbitrary code execution, privilege escalation, or denial of service. The flaw affects systems using ATM (Asynchronous Transfer Mode) LAN Emulation Client functionality, present since Linux kernel version 2.4 (commit 1da177e4c3f4). EPSS score of 0.02% (7th percentile) suggests low probability of mass exploitation. Vendor patches available across all maintained stable branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). Not listed in CISA KEV; no public exploit code identified at time of analysis.

Use-after-free in Linux kernel GPIB subsystem allows local authenticated attackers with low privileges to execute arbitrary code, escalate privileges, or crash the system. The vulnerability occurs in IBRD, IBWRT, IBCMD, and IBWAIT ioctl handlers when concurrent IBCLOSEDEV calls free descriptors still in use by I/O operations. EPSS probability is very low (0.02%, 4th percentile), indicating minimal observed exploitation activity. Vendor patches available for stable branches 6.18.22, 6.19.12, and mainline 7.0 via commits cae26eff, 28c75dd1, and d1857f82.

Authentication bypass in the Temporary Login WordPress plugin (versions ≤1.0.0) allows remote unauthenticated attackers to authenticate as any temporary login user via a single crafted GET request. The vulnerability exploits a type juggling flaw where passing 'temp-login-token' as an array bypasses validation checks and causes WordPress to return all users with temporary login tokens, enabling complete account takeover without knowledge of valid credentials. CVSS 9.8 (Critical) with network attack vector and no prerequisites. EPSS data not available; exploitation requires the presence of active temporary login accounts created by site administrators.

Local privilege escalation in AGL app-framework-binder (afb-daemon) through v19.90.0 allows any low-privileged process to execute privileged supervision commands without authentication via an unprotected abstract Unix socket. Attackers can terminate the daemon (DoS), execute arbitrary API calls, close user sessions, or exfiltrate global configuration data. The vulnerability stems from commit b8c9d5de384 (2017-06-29) implementing 8 supervision commands with zero credential verification, acknowledged by developers as lacking DAC protection. EPSS data unavailable, not in CISA KEV, but technical details are publicly documented with proof-of-concept reference.

Cross-project privilege escalation in OpenStack Keystone (releases 13 through 29) lets a holder of an unrestricted application credential for one project mint an EC2-type credential targeting a different project, because POST /v3/credentials never validates that the caller-supplied project_id matches the authenticating app credential's project. Exchanging that EC2 credential at /v3/ec2tokens then yields a Keystone token scoped to the second project while retaining the original app_cred_id, enabling lateral movement across tenants. There is no public exploit identified at time of analysis and EPSS is very low (0.01%), but the authorization flaw (CWE-863) is confirmed and patched by upstream and distributors.

Authenticated users with restricted permissions in Kirby CMS can access pages and files they should not be able to view, bypassing configured access controls in the Panel and REST API. This affects Kirby installations where administrators have explicitly disabled `pages.access`, `pages.list`, `files.access`, or `files.list` permissions for specific user roles through blueprints. The vulnerability allows information disclosure of content models that should be hidden, though write operations remain protected. Patched versions 4.9.0 and 5.4.0 are available from the vendor. No public exploit identified at time of analysis, with EPSS data unavailable for this recent disclosure.

Arcane's Huma backend exposes four GET endpoints (`/api/templates*`) without authentication, allowing remote unauthenticated attackers to read all stored Docker Compose templates including plaintext environment files containing database passwords, API keys, and OAuth secrets. The vulnerability affects Arcane backend versions prior to 1.18.0. Because Arcane's "Save as Template" workflow persists production secrets verbatim into these templates, this is not theoretical information disclosure but direct credential theft. The frontend correctly treats these paths as authenticated, revealing a backend authorization gap (CWE-862). Vendor-released patch available in version 1.18.0. No active exploitation or public exploit code identified at time of analysis, though the attack is trivial (CVSS:4.0 AV:N/AC:L/PR:N).

Unauthenticated remote disclosure of user-uploaded images in IBM Langflow Desktop 1.0.0-1.8.4 allows network attackers to enumerate and access other users' private images through predictable object references. With CVSS 7.5 (High) reflecting unauthenticated network exploitation, and EPSS data not provided, risk depends on whether installations expose the vulnerable endpoint to untrusted networks. No KEV listing or public exploit code identified at time of analysis, suggesting discovery through vendor security review rather than active exploitation.

Identity collision in the go-pkgz/auth Patreon OAuth provider allows any Patreon-authenticated user to impersonate every other Patreon user in the same application. The Patreon provider hashes an uninitialized variable instead of the actual Patreon account ID, assigning the constant value patreon_da39a3ee5e6b4b0d3255bfef95601890afd80709 to all users. Applications using token.User.ID as the stable account key can experience cross-account access, privilege escalation, and data leakage. Vendor-released patch available in versions 1.25.2 and 2.1.2. No evidence of active exploitation or public POC beyond the vendor's disclosure, but the vulnerability is trivially exploitable with remote unauthenticated access to any affected application.

Account takeover via SAML SSO authentication bypass in Sentry allows attackers to hijack arbitrary user accounts when controlling a malicious SAML Identity Provider within multi-organization instances. Attackers with permissions to configure SSO settings in one organization can link a victim's email address to their malicious IdP, then authenticate as that victim across the instance. The vulnerability was responsibly disclosed via bug bounty, patched in version 26.4.1 (deployed to SaaS in April 2026), and requires knowledge of the victim's email address plus multi-organization deployment (SENTRY_SINGLE_ORGANIZATION = False). No public exploit identified at time of analysis, though technical details and patch code are public via GitHub advisory GHSA-rcmw-7mc7-3rj7.

SQL injection in SSCMS v7.4.0 enables high-privileged attackers to execute arbitrary SQL statements via the stl:sqlContent tag's queryString attribute. Attackers with administrative access can craft encrypted payloads to the /api/stl/actions/dynamic endpoint, bypassing parameterization controls to achieve database compromise, authentication bypass, or complete data exfiltration. EPSS data not available; no confirmed active exploitation (CISA KEV negative); public exploit code availability unknown but detailed technical advisory published by VulnCheck increases weaponization risk.

Unauthenticated remote attackers can access and refresh private chart data in Chartbrew 4.9.0 via an exposed API endpoint. The POST /api/chart/:chart_id/query endpoint lacks authentication checks and fails to validate whether charts belong to public reports or if sharing policies permit access. Attackers possessing a chart identifier can retrieve sensitive data from private dashboards without credentials. EPSS data not available. Not listed in CISA KEV. Vendor-confirmed vulnerability with patch released in version 5.0.0.

Authenticated users in Chartbrew 4.9.0 can modify or delete dashboard sharing policies across projects they don't own due to insufficient authorization checks. An attacker with legitimate access to one project can manipulate SharePolicy records (visibility settings, passwords, allowed parameters, expiration dates) for dashboards in any other project within the same Chartbrew instance. While CVSS rates this 8.1 HIGH, real-world risk depends heavily on multi-tenancy deployment: single-organization instances face lower insider threat exposure than multi-tenant SaaS scenarios. EPSS data not available. No public exploit identified at time of analysis, though exploitation requires only basic authenticated API access.

Chartbrew 4.9.0 allows unauthenticated attackers to access hidden chart data via authentication bypass in public chart export routes. Attackers who know a chart identifier in any public project can read or export charts that were intentionally excluded from public reports, bypassing SharePolicy access controls. The vulnerability requires only network access and a valid chart ID, with no authentication or user interaction needed. Patched in version 5.0.0 per vendor advisory GHSA-mq7q-6xh6-5649. No public exploit identified at time of analysis, though exploitation complexity is low (CVSS AC:L).

Horizontal privilege escalation in Chartbrew 4.9.0 allows authenticated low-privilege team members to access datasets, data requests, and database connections belonging to other projects within the same team. Attackers with credentials to any single project can read, modify, create, and delete data assets across all sibling projects by exploiting missing project-level authorization checks on multiple API endpoints. This enables cross-project data exfiltration and unauthorized execution of victim database queries remotely with low complexity (EPSS not provided, no CISA KEV listing, vendor-patched in v5.0.0).

Silent dependency checksum bypass in hexpm/hex package manager (versions 0.16.0 through 2.4.1) allows attackers to substitute malicious dependencies without detection. The Hex.RemoteConverger module fails to verify lockfile checksums due to a string-versus-atom type mismatch in the verification logic, causing the security check to be silently skipped. Attackers who can poison local package caches or compromise registry responses can deliver modified packages that overwrite mix.lock without raising alerts. SSVC framework indicates proof-of-concept exists, attack is non-automatable (requires user interaction and precise timing), with total technical impact. Fixed in version 2.4.2 (commit d7528c8).

Certificate name-constraints bypass in GnuTLS allows a remote attacker to craft a leaf certificate whose Subject Alternative Name differs only in letter casing from a constrained dNSName or rfc822Name, causing GnuTLS to accept a certificate that its excludedSubtrees/permittedSubtrees policy should reject. The flaw stems from case-sensitive comparison of name-constraint labels and enables unauthorized access, impersonation, or information disclosure across software (notably Red Hat Enterprise Linux 6-10 and OpenShift Container Platform 4) that relies on GnuTLS for X.509 validation. SSVC notes a public proof-of-concept exists, though EPSS exploitation probability is very low (0.03%, 9th percentile) and the issue is not in CISA KEV.

Authentication bypass in Progress MOVEit Automation allows remote unauthenticated attackers to completely circumvent authentication controls and gain unauthorized access with high impact to confidentiality, integrity, and availability. Affects all versions before 2025.0.9, all 2024.x versions before 2024.1.8, and all versions prior to 2024.0.0. Progress Software has released patches for all supported versions. CVSS 9.8 critical severity with network-accessible, low-complexity exploitation requiring no privileges or user interaction. No public exploit or active exploitation confirmed at time of analysis, though the authentication bypass nature and MOVEit's history as a high-value target make this a priority remediation candidate.

Unauthenticated attackers can bypass Stripe payment gates in Otter Blocks for WordPress ≤3.1.4 by forging the 'o_stripe_data' cookie with publicly visible product IDs from checkout block HTML source, gaining unauthorized access to premium content. The plugin's 'get_customer_data' method accepts unsigned cookie data without server-side Stripe API verification for one-time purchases, enabling trivial exploitation with no authentication required. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) reflects high confidentiality impact from accessing gated content. EPSS data unavailable; no active exploitation or POC confirmed at time of analysis, but the attack requires only basic HTTP cookie manipulation skills.

Remote authenticated attackers can bypass authorization controls in MeWare PDKS through user-controlled key manipulation, enabling privilege escalation to access and modify sensitive data without proper permissions. Affecting PDKS versions from V16.20200313 to VMYR_3.5.2025117, this vulnerability allows low-privileged users to abuse authorization mechanisms via network access without user interaction. No confirmed active exploitation or public exploit code identified at time of analysis, with EPSS data unavailable for risk quantification.

Brute-force attacks against U-SPEED N300 router V1.0.0 can compromise administrator credentials due to missing rate limiting on the /api/login endpoint. Local network attackers can execute unlimited authentication attempts without account lockout, enabling credential compromise and unauthorized access to router management. SSVC indicates proof-of-concept exists and the attack is automatable with partial technical impact. CVSS 7.5 reflects network accessibility, but the vulnerability description specifies 'local network' access requirement, suggesting the actual attack vector may be more constrained than the AV:N metric indicates.

Inverted authorization logic in Admidio's two-factor authentication reset module allows non-admin users with profile edit permissions to strip TOTP protection from administrator accounts while paradoxically blocking users from resetting their own 2FA. A group leader holding 'hasRightEditProfile()' rights on an admin account can send a single POST request to /adm_program/modules/profile/two_factor_authentication.php with the admin's UUID, disabling the admin's 2FA and reducing account security to password-only. This vulnerability affects Admidio versions ≤5.0.8; patched version 5.0.9 corrects the inverted comparison operator. Public exploit code exists via the GitHub advisory's proof-of-concept. No confirmed active exploitation (not in CISA KEV).

Authenticated users with shared workflow access in n8n can exfiltrate other users' API credentials by injecting foreign credential IDs into dynamic-node-parameters endpoint requests. The vulnerability forces the n8n backend to decrypt and replay stolen credentials against attacker-controlled URLs, enabling credential theft across workflow collaborators. Affects npm package n8n versions <1.123.33 and 2.17.0-2.17.4, with vendor-confirmed patches available in 1.123.33 and 2.17.5. No public exploit identified at time of analysis, though CVSS 8.5 with scope change (S:C) reflects the multi-tenant credential boundary violation.

Checksum and size-validation bypass in Amazon's FreeRTOS-Plus-TCP stack (versions 4.0.0 through 4.2.5 and 4.3.0 through 4.4.0) lets an adjacent-network attacker inject malformed packets by spoofing the Ethernet source MAC to match one of the device's own registered endpoint MACs, causing the loopback-detection path to skip all input validation. This is a CWE-290 spoofing/authentication-bypass flaw carrying a CVSS 4.0 base of 7.1 with integrity-only impact and no confidentiality or availability loss. No public exploit identified at time of analysis, EPSS is 0.02% (4th percentile), and CISA SSVC rates exploitation as none and automatable as no, so real-world urgency is modest despite the medium-high score.

Incorrect authorization in SailPoint IdentityIQ lets an authenticated user who is the requestor or assignee of a work item edit the definition of a role even though they lack the capability that normally gates role editing. All versions prior to the 8.3p5, 8.4p4, and 8.5p2 patch levels are affected, enabling privilege-boundary bypass within the identity governance platform itself. There is no public exploit identified at time of analysis, and the EPSS probability is very low (0.04%), but the technical impact is rated total because roles drive downstream access across connected systems.

Authentication bypass in cPanel & WHM allows unauthenticated remote attackers to gain unauthorized access to the control panel by exploiting a flaw in the login flow. The vulnerability is confirmed actively exploited (CISA KEV) with publicly available exploit code, an EPSS score of 16.52% (95th percentile), and affects multiple long-term support branches of cPanel & WHM as well as WP Squared. Given that cPanel administers shared hosting environments, successful exploitation typically grants attackers control over many downstream customer sites.

Authentication bypass in TUBITAK BILGEM Pardus (versions <=0.6.4 up to 0.8.0) stems from improper neutralization of CRLF sequences, letting remote attackers manipulate protocol/header handling to circumvent authentication controls when a user is lured into triggering the crafted request. Reported by TR-CERT, the flaw carries a CVSS 8.8 with total technical impact per CISA SSVC, though EPSS is very low (0.05%, 17th percentile) and there is no public exploit identified at time of analysis. A vendor patch (0.8.0) is available.

Sensitive information disclosure in C-DAC's e-Sushrut Hospital Management Information System (HMIS) allows an authenticated attacker to access data belonging to other users by decoding and tampering with Base64-encoded parameters carried in request URLs. Because Base64 is a reversible encoding rather than a cryptographic control, a low-privileged logged-in user can enumerate or alter these object references (CWE-639) to reach records they are not authorized to view. This was reported by CERT-In (CIVN-2026-0207); there is no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.05%).

Insecure Direct Object Reference (IDOR) in C-DAC's e-Sushrut Hospital Management Information System (HMIS) lets an authenticated attacker read other patients' records by tampering with encoded identifiers in the request URL. Any logged-in, low-privilege user (per CVSS PR:L) can pivot from their own session to arbitrary patient accounts, exposing sensitive medical data. Reported to CERT-In (CIVN-2026-0207); no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.05%).

Unauthorized patient-data disclosure in C-DAC's e-Sushrut Hospital Management Information System (HMIS) allows an authenticated user to read other patients' sensitive records by tampering with an identifier parameter in an API request URL. The flaw is a classic insecure-direct-object-reference (IDOR) authorization gap reported by CERT-In (CIVN-2026-0207); there is no public exploit identified at time of analysis and EPSS estimates exploitation probability at only 0.05%, but the low attack complexity makes abuse trivial for any logged-in account.

Account takeover in C-DAC's e-Sushrut Hospital Management Information System (HMIS) arises because one-time passwords (OTPs) are returned in plaintext inside API responses, letting a remote attacker who can observe those responses harvest a valid OTP and impersonate the targeted user. CERT-In flagged the flaw (CIVN-2026-0207) and it is tagged as an authentication bypass; there is no public exploit identified at time of analysis and EPSS exploitation probability is low at 0.17%. The CVSS 4.0 vector rates it 8.8 with high confidentiality impact and no privileges or user interaction required.

Authentication bypass in CDAC-Noida's e-Sushrut Hospital Management Information System (HMIS) lets remote attackers gain unauthorized access to user accounts by tampering with server responses. The login flow trusts client-side response parameters to decide whether authentication succeeded, so an attacker who intercepts and rewrites the response is treated as authenticated. Reported by CERT-In (CIVN-2026-0207); no public exploit identified at time of analysis, and EPSS is low at 0.31% (54th percentile).

Broken access control in the SureForms Pro WordPress form-builder plugin (versions up to and including 2.8.0) lets remote unauthenticated attackers reach functionality that should be protected by capability checks, resulting in limited confidentiality, integrity, and availability impact. The flaw stems from missing authorization (CWE-862) on incorrectly configured access-control security levels rather than a memory-safety or injection bug. EPSS is very low (0.01%, 2nd percentile) and there is no public exploit identified at time of analysis, though SSVC rates the flaw as automatable with partial technical impact.

TSIG authentication bypass in CoreDNS before v1.14.3 allows unauthenticated network attackers to defeat TSIG protections on the gRPC, QUIC, DoH, and DoH3 transports and reach TSIG-gated functionality such as AXFR/IXFR zone transfers and dynamic updates. The gRPC/QUIC paths validate only the TSIG key name and never call dns.TsigVerify(), while DoH/DoH3 hardcode TsigStatus() to nil so any TSIG record - even one with an invalid key name and garbage MAC - is treated as verified. A detailed PoC demonstrates full zone dumps over forged requests; this is confirmed actively exploited status is not present (no public exploit identified at time of analysis beyond the reporter's PoC), and EPSS is low at 0.05%.

TSIG authentication bypass in CoreDNS before 1.14.3 lets unauthenticated remote clients defeat the tsig plugin's `require all` policy on every encrypted transport (DoT, DoH, DoH3, DoQ, and gRPC). Because the plugin trusts each transport writer's TsigStatus() rather than verifying the signature itself, transports that never populate a TSIG secret return a nil status and treat invalid or unsigned requests as authenticated, granting access to zone data or privileged queries the operator meant to restrict. Publicly available exploit code (a reproducer PoC) exists, but EPSS is low (0.07%, 21st percentile) and it is not on CISA KEV, so there is no confirmed active exploitation at time of analysis.

Improper authorization in CoreDNS' transfer plugin (versions before 1.14.3) lets a remote client bypass a restrictive subzone AXFR/IXFR ACL and dump the subzone's full contents. The flaw stems from longestMatch() selecting the transfer stanza by lexicographic string comparison instead of true longest-suffix match, so a permissive parent-zone rule can override a stricter child-zone rule for certain zone names. Publicly available exploit code exists (author-provided PoC) but there is no evidence of active exploitation, and EPSS is very low at 0.04%.

Cross-workspace document disclosure in Outline (getoutline) versions 0.86.0 through 1.6.x lets an authenticated user mint a public share link for any document on the platform, then read its full contents. The flaw is an insecure direct object reference (IDOR) in the shares.create API: when a request supplies both collectionId and documentId, authorization validates only the collection and never checks that the caller may access the named document, so it works even against documents in other workspaces. A proof-of-concept is referenced by the GitHub advisory (SSVC 'poc'), but EPSS is very low (0.03%, 7th percentile) and it is not in CISA KEV, so this is publicly demonstrated but not confirmed as actively exploited.

Root command execution on Snap One WattBox 800 and 820 series power-management devices running firmware before 2.10.0.0 is possible through undisclosed diagnostic HTTP endpoints whose only authentication is the device MAC address and service tag - values printed in plaintext on the unit's physical label. Anyone who can read the label, or documentation/photos containing those values, can authenticate and run arbitrary commands as root. No public exploit identified at time of analysis, and the flaw is not on the CISA KEV list; EPSS is low at 0.07%.

Privilege escalation via authentication bypass in OpenClaw before 2026.4.8 allows a previously paired node to reconnect and gain an expanded, exec-capable command set without satisfying the operator.admin re-pairing scope check. Rooted in CWE-863 (incorrect authorization), the flaw lets an attacker who was once paired execute privileged commands on the local assistant host. There is no public exploit identified at time of analysis and it is not in CISA KEV; EPSS is very low at 0.02% (6th percentile), consistent with a local, precondition-dependent issue rather than an internet-wide threat.

Persistent browser-profile tampering in OpenClaw before 2026.4.8 lets a low-privileged actor reach the node.invoke(browser.proxy) code path, which fails to enforce the browser.request persistent profile-mutation guard. Because OpenClaw is a user-controlled local assistant, an actor able to drive node.invoke can rewrite persisted browser configuration (notably proxy settings) that the guard was meant to protect. There is no public exploit identified at time of analysis, EPSS is very low (0.03%, 7th percentile), and CISA SSVC records no observed exploitation.

Improper authorization in OpenClaw before 2026.4.8 lets users holding the broad operator.write scope approve node pairing that should require the narrower operator.pairing scope plus admin, granting them unauthorized control of exec-capable nodes. Reported by VulnCheck and credited to Tencent Zhuque Lab, it carries a CVSS 4.0 score of 8.7 with total technical impact, though there is no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.03%). A vendor patch (npm 2026.4.8) is available.

Explicit-approval bypass in OpenClaw before 2026.4.8 lets an attacker with low-privileged access to gateway or node exec hosts run inline eval commands that the strictInlineEval control is supposed to gate behind manual user approval. The flaw is a fail-open approval-timeout fallback: when an approval prompt is not answered in time, the system permits the eval instead of denying it, defeating the intended trust boundary. No public exploit identified at time of analysis; EPSS is very low (0.04%, 12th percentile) and CISA SSVC records no observed exploitation, though technical impact is rated total.

Improper authorization in OpenClaw's device.token.rotate function (versions before 2026.4.8) lets a low-privileged actor mint or preserve device tokens carrying roles and scopes that never passed the intended role-upgrade pairing approval, effectively escalating privilege within the assistant's trust model. The flaw was reported by VulnCheck and Tencent Zhuque Lab and carries a CVSS 4.0 base score of 7.7 (High), but there is no public exploit identified at time of analysis and EPSS is negligible (0.04%, 11th percentile). SSVC rates exploitation as none and automatable as no, while technical impact is total.

Privilege escalation in OpenClaw's trusted-proxy authentication mode allows low-privileged authenticated users to gain operator.admin privileges by declaring operator scopes on non-Control-UI clients. The incomplete scope-clearing mechanism fails to sanitize self-declared scopes when identity-bearing authentication paths process requests, enabling attackers to bypass authorization checks and achieve full administrative access. Vendor patch available via commit 8b88b927 in version 2026.3.31; no confirmed active exploitation (not in CISA KEV) but publicly disclosed with detailed GitHub security advisory increasing attack feasibility.

Sandbox escape in OpenClaw file synchronization before version 2026.3.31 enables remote authenticated attackers to read and write arbitrary files outside intended boundaries via crafted symlinks during mirror sync operations. The vulnerability exploits CWE-59 (Improper Link Resolution Before File Access) with attack complexity rated High and requires low privileges, indicating targeted exploitation scenarios. Vendor patches available via GitHub commits c02ee8a and 3b9dab0, with CVSS 7.6 reflecting high confidentiality and integrity impact but no availability impact. No active exploitation or public POC identified at time of analysis beyond vendor disclosure.

Webhook replay attacks in OpenClaw before 2026.3.28 allow remote attackers to trigger duplicate voice-call processing by reordering query parameters in captured Plivo V3 signed webhooks. The vulnerability stems from inconsistent canonicalization: signature verification sorts query parameters before validation, but replay detection hashes the raw URL with original parameter ordering. Attackers possessing a single valid signed webhook can bypass replay cache indefinitely by permuting query string order, causing repeated execution of voice-call workflows without requiring authentication or cryptographic breaks. No public exploit identified at time of analysis, though attack complexity is low (CVSS AC:L) with network vector (AV:N) requiring no privileges (PR:N).

Authentication bypass in OpenClaw allows remote unauthenticated attackers to execute privileged runtime operations intended for authorized operators. The vulnerability exists in plugin-auth HTTP routes that incorrectly grant operator-level write scopes without authentication checks. Attackers can remotely exploit this flaw with low complexity (CVSS:4.0 AV:N/AC:L/PR:N) to modify runtime configurations and perform administrative actions. Vendor-released patch available as of commit 2a1db0c (March 31, 2026). No active exploitation confirmed in CISA KEV, though EPSS data unavailable for risk calibration.

Privilege escalation in OpenClaw before 2026.3.28 allows local authenticated attackers to bypass execution allowlist controls via wrapper binary persistence. When users grant trust to wrapped commands (e.g., via /usr/bin/script), OpenClaw fails to distinguish the wrapper from the underlying executable, allowing attackers to reuse the wrapper's persistent trust to execute arbitrary unauthorized programs. No active exploitation confirmed (CISA KEV: not listed), but VulnCheck has published technical advisory details. EPSS data not available.

Plaintext private key storage in OpenClaw versions before 2026.3.31 exposes Nostr protocol signing keys through configuration retrieval methods. Authenticated attackers with network access can exploit redaction bypass in config.get methods to extract unencrypted private keys, enabling full impersonation of the compromised Nostr identity for signing and authentication operations. Vendor patch available via GitHub commit 57700d716f660591fb6e09727f3ca8041fa48b9d. EPSS and KEV data not available, but the authentication bypass tag and network attack vector indicate elevated risk for multi-tenant or shared OpenClaw deployments.

Privilege escalation in OpenClaw versions prior to 2026.3.28 enables authenticated operators with write permissions to modify administrator-only voice configuration settings through the chat.send endpoint. This vulnerability allows low-privileged operator accounts to manipulate sensitive Talk Voice configuration persistence, bypassing intended role-based access controls. A vendor-released patch is available via commit e34694733fc64931ed4a543c73d84ad3435d5df1. EPSS data unavailable; no CISA KEV listing or public exploit code identified at time of analysis, though the targeted nature (authenticated internal operators) suggests lower mass-exploitation risk than the CVSS 7.1 score might imply.

Remote code execution in OpenClaw gateway versions before 2026.3.31 allows attackers with trusted paired node credentials (role=node) to escalate privileges and execute arbitrary code on the gateway by abusing unrestricted agent.request dispatch functionality. The vulnerability stems from insufficient access controls on node.event agent requests, enabling low-privilege paired nodes to invoke gateway-side tools without restriction. EPSS exploitation probability and KEV status not yet available for this recently disclosed vulnerability, but a vendor patch and exploit details are publicly documented.

Authorization bypass in OpenClaw phone channel endpoints allows authenticated low-privilege users to arm or disarm phone-based alarm channels without required administrative rights. Versions prior to 2026.3.28 fail to validate operator.admin scope for /phone arm and /phone disarm API endpoints when accessed through external channels (CWE-863). Patch released via GitHub commit aa66ae1fc, with CVSS 7.1 reflecting network-accessible integrity impact requiring only low-privilege authentication. No active exploitation confirmed (not in CISA KEV); exploit development straightforward given simple API authorization flaw.

Authentication bypass in NVIDIA NVFlare Dashboard allows remote unauthenticated attackers to escalate privileges through user-controlled key manipulation in the authentication system. The vulnerability affects the NVIDIA Flare SDK and enables complete system compromise including arbitrary code execution, data tampering, information disclosure, and denial of service. With a CVSS score of 9.8 (critical severity) and maximum exploitability metrics (AV:N/AC:L/PR:N/UI:N), this represents a severe security flaw requiring immediate remediation, though no active exploitation (KEV) or public exploit code has been identified at time of analysis.

Carlson Software VASCO-B GNSS receivers allow remote unauthenticated attackers to fully access and modify device configuration and operational functions due to complete absence of authentication controls (CWE-306). The network-accessible interface requires no credentials, enabling attackers to compromise device integrity and availability with low attack complexity. EPSS and KEV status not provided in available data; exploitation requires only network connectivity to the device management interface, typical in surveying and precision agriculture deployments where GNSS receivers may be exposed on operational networks.

Authentication bypass in Netmaker (Gravitl) versions prior to 1.5.0 lets remote unauthenticated attackers forge host JWTs because VerifyHostToken in logic/jwts.go never validates the token signature. An attacker can sign a token with any arbitrary key to impersonate any host and reach host-scoped API endpoints, exposing sensitive network topology and peer information. SSVC lists a public proof-of-concept and rates the flaw automatable; EPSS is low (0.04%) and it is not on CISA KEV, so publicly available exploit code exists but no active exploitation is confirmed.

Privilege escalation in MphRx Minerva V3.6.0 allows authenticated users with user modification privileges to gain administrator access by manipulating the 'identifier' field in direct HTTP requests to the '/minerva/moUser/update' endpoint. While the vulnerability requires existing low-level authenticated access and cannot be exploited through the graphical interface, the CVSS v4.0 score of 8.5 reflects high impact across confidentiality, integrity, and availability in the subsequent system context (SC:H/SI:H/SA:H). No public exploit identified at time of analysis, with EPSS data unavailable for this recent CVE.

Insecure direct object reference in MphRx Minerva V3.6.0 allows authenticated attackers to enumerate and exfiltrate sensitive user data across the entire application by manipulating user IDs in the '/minerva/moUser/show/' endpoint. The CVSS 4.0 score of 8.5 reflects high confidentiality impact to both vulnerable (VC:H) and subsequent (SC:H) systems, with subsequent high integrity (SI:H) and availability (SA:H) impacts indicating potential for lateral movement or privilege escalation after initial data disclosure. Coordinated disclosure by INCIBE-CERT suggests vendor notification occurred, though no public exploit code is currently identified and EPSS/KEV data are unavailable for this 2026 CVE.

Insecure direct object reference in MphRx Minerva V3.6.0 allows authenticated attackers to modify arbitrary user profiles via the '/minerva/user/updateUserProfile' endpoint, enabling account takeover by changing victim email addresses and triggering password reset flows. Reported by INCIBE-CERT with authentication bypass tags, indicating likely real-world discovery during security assessment. CVSS 9.4 reflects high confidentiality, integrity, and scope impacts (VC:H/VI:H/SC:H/SI:H), though the PR:L requirement (low-privileged authenticated access) limits initial attack surface to users with valid credentials.

Client-side authentication bypass in mpGabinet 23.12.19 and earlier allows local authenticated attackers to impersonate arbitrary users by patching the application binary. An attacker with legitimate low-privilege access to the system can manipulate the compiled application code to skip login verification entirely, gaining unauthorized access as any user including administrators. EPSS score not available for this 2026 CVE; no active exploitation or public POC confirmed at time of analysis.

Remote unauthenticated access to sensitive data in VEGA VEGAPULS 6X Two-Wire industrial sensors exposes hashed credentials and access codes via unsecured configuration interface. Network-accessible interface (AV:N/AC:L/PR:N/UI:N) allows attackers to extract authentication materials without any prerequisites, enabling credential cracking and potential lateral movement in industrial networks. EPSS and KEV data not available; CERTVDE advisory confirms vulnerability in Ethernet-APL enabled industrial level measurement devices running PROFINET, Modbus TCP, and OPC UA protocols. No public exploit identified at time of analysis, though exploitation trivial due to lack of authentication requirement.

Privilege escalation in OpenClaw chat.send API allows low-privileged gateway callers with write scope to execute admin-only session management operations. Attackers can forcibly reset user sessions, rotate session IDs, and archive chat transcripts without admin authorization by exploiting broken access control in the chat messaging path. This enables session hijacking and data manipulation attacks against legitimate users. Reported by VulnCheck disclosure team with vendor security advisory published; no public exploit or active exploitation confirmed at time of analysis.

Authentication bypass in Spring Boot 4.0.0-4.0.5 allows remote unauthenticated attackers to access all application endpoints, bypassing default web security filters entirely. Affects servlet-based applications using spring-boot-actuator-autoconfigure without custom Spring Security configuration and without spring-boot-health dependency. Vendor patch released (upgrade to 4.0.6+). No public exploit code identified at time of analysis, but CVSS 9.1 with network attack vector (AV:N/AC:L/PR:N) indicates trivial exploitation once configuration prerequisites are met.

Hard-coded credentials in Milesight AIOT camera firmware allow adjacent network attackers to gain full system access without authentication. CISA ICS-CERT has published an advisory, indicating industrial/IoT deployment concern. The CVSS 7.7 score reflects adjacent network vector (AV:A) with low complexity (AC:L) and no authentication required (PR:N), enabling complete compromise of confidentiality, integrity, and availability on vulnerable devices. Firmware-level credential hardcoding (CWE-798) cannot be disabled through configuration changes, making patching critical for exposed industrial camera deployments.

Authorization bypass in Milesight AIOT network cameras stems from weak cryptographic key generation in specific firmware builds, letting an adjacent attacker defeat authentication controls and gain unauthorized access to camera functions. The affected line spans a broad catalog of Milesight IP camera and NVR models (MS-Cxx and MS-Nxxxx series). No public exploit identified at time of analysis; EPSS is negligible at 0.01% and CISA SSVC records no observed exploitation, so this is a disclosed-but-not-yet-exploited ICS/IoT issue.

Sensitive data disclosure in ProjeQtor 7.0 through 12.4.3 lets an authenticated guest-level user retrieve other users' records - including password hashes and API keys - by directly calling the objectDetail.php endpoint, which fails to enforce ownership or role checks (CWE-862). Because the exposed administrator credentials enable privilege escalation, the flaw effectively promotes a low-privilege account to full control. Publicly available exploit code exists, though EPSS is low (0.06%, 18th percentile) and it is not on CISA KEV, indicating no public exploit identified as actively used in the wild.

Authentication bypass in MERCURY MIPC252W IP camera 1.0.5 allows remote unauthenticated attackers to hijack authenticated RTSP sessions and execute unauthorized camera control commands. After an initial valid Digest authentication in a DESCRIBE request, the device fails to validate subsequent RTSP request credentials (SETUP, PLAY, TEARDOWN), accepting empty or invalid Authorization headers as long as session parameters match. This enables complete camera takeover including video stream access, configuration changes, and service disruption without credential brute-forcing. EPSS score of 0.01% suggests minimal observed exploitation activity, though the attack complexity is low (AV:N/AC:L/PR:N) and public PoC exists on GitHub.

Remote authentication bypass in note-mark backend allows unauthenticated attackers to hijack OIDC user accounts by submitting the password 'null' to the internal login endpoint. Affected deployments running default configuration (EnableInternalLogin=true) with OIDC enabled permit complete account takeover of any OIDC-registered user. Attackers gain full access to private notebooks, markdown content, and uploaded assets, plus can persist access by overwriting the victim's password. Vendor patch available in commit dea5530c. CVSS 9.4 (AV:N/AC:L/PR:N/UI:N) reflects the zero-interaction remote attack against default installations. No EPSS or KEV data available, but the detailed POC script in the advisory significantly lowers exploitation barrier.

Authentication/authorization bypass in Clerk's official JavaScript SDKs (@clerk/nextjs, @clerk/nuxt, @clerk/astro, and the underlying @clerk/shared) allows unauthenticated remote attackers to defeat middleware-based route protection: a crafted request evades createRouteMatcher so that clerkMiddleware never invokes auth.protect(), letting the request reach protected downstream handlers such as API routes and server components. Sessions are not compromised and no user is impersonated — only the middleware gating decision is bypassed — so real impact is confined to apps that rely solely on middleware gating without redundant checks in their handlers. CVSS is 9.1 and SSVC rates technical impact as total, but there is no public exploit identified at time of analysis and EPSS is low at 0.09% (26th percentile).

Unauthenticated database writes in CyberPanel versions before 2.4.4 allow remote attackers to abuse two AI Scanner worker endpoints (/api/ai-scanner/status-webhook and /api/ai-scanner/callback) that ship without authentication checks (CWE-306). Because no credentials are required (CVSS 4.0 PR:N/UI:N), any attacker who can reach the panel can flood the database, corrupt scan-history records, and pollute stored fields, degrading integrity and availability. Publicly available exploit code exists and the flaw was reported by VulnCheck, though EPSS remains low at 0.21% and it is not listed in CISA KEV.

Local privilege escalation in Deskflow (all versions up to 1.20.0 stable and 1.26.0.134 continuous) allows any low-privilege Windows user to execute arbitrary commands as SYSTEM by accessing an unauthenticated IPC named pipe. The daemon runs with SYSTEM privileges and processes commands without validating caller identity due to WorldAccessOption configuration. No public exploit identified at time of analysis, but the attack vector is straightforward for local users with basic Windows IPC knowledge.

Metadata integrity bypass in AWS tough (TUF client library) before v0.22.0 allows authenticated users with delegated signing authority to poison local metadata caches by bypassing expiration, hash, and length validation checks. The vulnerability exists because load_delegations skips specification-mandated integrity checks applied to top-level targets metadata, enabling malicious delegated signers to inject invalid metadata. AWS has released patches in tough-v0.22.0 and tuftool-v0.15.0. CVSS 7.1 reflects network vector but high attack complexity (AT:P indicates specialized conditions). No public exploit or active exploitation confirmed at time of analysis, though authentication bypass tag suggests significant trust boundary violation.

Signature duplication in AWS Tough TUF client prior to v0.22.0 allows authenticated attackers to bypass threshold signature requirements for delegated role metadata by reusing a single valid signature multiple times. The flaw undermines TUF's multi-signature integrity model, enabling acceptance of forged metadata with reduced cryptographic validation. Vendor patch available (tough-v0.22.0, tuftool-v0.15.0). No public exploit code or active exploitation confirmed at time of analysis, but CVSS 7.0 reflects high integrity impact to both vulnerable and downstream systems.

Authorization bypass in the @better-auth/oauth-provider plugin for Better Auth (versions >= 1.4.8-beta.7 and < 1.6.5, plus 1.7.0-beta.0/1.7.0-beta.1) lets any authenticated user register OAuth clients even when the clientPrivileges option was configured to gate the create action. The OAuth client creation endpoints (/oauth2/create-client and /admin/oauth2/create-client) never invoked the clientPrivileges hook before persisting new records, so restrictions on client registration were silently ineffective. Publicly available exploit code exists; EPSS is low (0.05%) and SSVC lists no observed exploitation, indicating limited real-world weaponization to date.

Authentication bypass in Budibase low-code platform (versions prior to 3.35.4) allows remote unauthenticated attackers to access any protected API endpoint by appending a public endpoint path as a query parameter. The vulnerability stems from unanchored regular expressions in authentication middleware that match against the full request URL including query strings, enabling attackers to craft requests like 'POST /api/global/users/search?x=/api/system/status' to bypass all authentication checks. CVSS score of 9.1 (Critical) reflects network-based remote exploitation with no authentication or user interaction required, resulting in high confidentiality impact and high availability impact. No public exploit code or active exploitation has been identified at time of analysis.

NO_PROXY protection bypass in Axios HTTP client (versions 1.0.0-1.15.0 and ≤0.31.0) lets an attacker who controls a request's target URL route loopback-bound traffic through an attacker-configured proxy by using any address in the 127.0.0.0/8 range other than 127.0.0.1 (e.g. 127.0.0.2, 127.1.2.3). This is an incomplete fix for CVE-2025-62718: the patch hardcoded only localhost, 127.0.0.1, and ::1 as loopback, ignoring RFC 1122's full /8 loopback block. Publicly available exploit code exists, but no public active exploitation is identified and EPSS is low (0.03%); it is fixed in 1.15.1 and 0.31.1.

Authentication bypass in Traefik's StripPrefixRegex middleware allows unauthenticated remote attackers to access protected resources when combined with ForwardAuth, BasicAuth, or DigestAuth. By inserting a percent-encoded dot (%2e) in the URL prefix, attackers exploit a length mismatch between decoded path matching and encoded path slicing, causing ForwardAuth to receive a dot-segment path (/./admin/secret) that bypasses protection rules while backend servers normalize it to the protected path (/admin/secret). Confirmed with working proof-of-concept against Traefik v3.6.11. Patches released for v2.11.43, v3.6.14, and v3.7.0-rc.2. No CVSS score assigned yet, but meets criteria for high severity given complete authentication bypass with network attack vector requiring no privileges or user interaction.

Claude Code's trust bypass vulnerability allows execution of malicious hooks through manipulated git worktree configuration files. Attackers who can trick victims into cloning a crafted repository can bypass the folder trust dialog by pointing the `commondir` file to a previously-trusted path, enabling immediate execution of arbitrary code via `.claude/settings.json` hooks. The attack requires the attacker to know or correctly guess a path the victim has already trusted, limiting exploitation to targeted scenarios. Auto-update users have already received the patch; manual installation users should upgrade immediately.
