joserfc: HS256/HS384/HS512 verify accepts empty/nil HMAC key (cross-language sibling of CVE-2026-45363)
joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption (JOSE) standards. Prior to 1.6.8, joserfc.jwt.decode accepts attacker-forged HMAC-signed tokens when the caller-supplied verification key is the empty string or None, because HMACAlgorithm.sign and HMACAlgorithm.verify in src/joserfc/_rfc7518/jws_algs.py pass the output of OctKey.get_op_key(...) to hmac.new(...) and OctKey.import_key in src/joserfc/_rfc7518/oct_key.py only emits a SecurityWarning for keys shorter than 14 bytes without rejecting zero-length input.

CVE-2026-55652 Crítica · 9.8 CWE-287 15/07/2026
Wekan: Header-login IP allowlist bypass via X-Forwarded-For spoofing in Wekan allows unauthenticated full account takeover (incl. admin)
Wekan is open source kanban built with Meteor. Prior to 9.46, header-login with HEADER_LOGIN_TRUSTED_IPS uses getRequestIp() in server/lib/headerLoginAuth.js to trust the client-supplied X-Forwarded-For header before the real socket address, allowing an unauthenticated attacker to send HEADER_LOGIN_ID for any username and receive a meteor_login_token session, including for admin. This issue is fixed in version 9.46.
CVE-2026-55445 Crítica · 9.3 CWE-287 15/07/2026
Qinglong: Incomplete fix for CVE-2026-3965: Improper Authentication
Qinglong is a timed task management platform supporting Python3, JavaScript, Shell, and Typescript. Prior to 2.20.1, the init guard middleware in back/loaders/express.ts checks /api/user/init but not /open/user/init, while rewrite('/open/*', '/api/$1') rewrites the whitelisted /open/* path after JWT authentication and the guard have passed; an unauthenticated attacker can send PUT /open/user/init to reset administrator credentials on an initialized instance. This issue is fixed in 2.20.1.
CVE-2026-52893 Crítica · 9.2 CWE-287 15/07/2026
Wekan: OIDC Account Takeover via Unconditional Email-Based Account Merge in onCreateUser hook
Wekan is open source kanban built with Meteor. Prior to 9.32, the Wekan Accounts.onCreateUser hook in server/models/users.js merges OIDC logins into existing accounts when the OIDC email or username matches an existing Wekan user, without verifying ownership or checking email_verified. An attacker using an OIDC provider account with a victim's email or username can cause Wekan to merge the attacker's OIDC credentials into the victim account and then log in as that account. This issue is fixed in version 9.32.
CVE-2026-53516 Alta · 8.3 CWE-287 15/07/2026
Better Auth: Account takeover via OAuth auto-link to unverified pre-registered email
Better Auth is an authentication and authorization library for TypeScript. Prior to 1.6.11, Better Auth's OAuth callback auto-link gate in handleOAuthUserInfo accepts implicit account linking when the OAuth provider asserts email_verified: true without requiring the local user row's emailVerified field to also be true, allowing an attacker who pre-registers a victim email through /sign-up/email to bind the victim's OAuth identity to the attacker's account. The same primitive affects one-tap, and emailAndPassword.requireEmailVerification: true does not mitigate the link-time verification change. This issue is fixed in version 1.6.11.
CVE-2026-53514 Alta · 7.7 CWE-287 15/07/2026
Better Auth: Unauthorized invitation acceptance via unverified email match in organization plugin
Better Auth is an authentication and authorization library for TypeScript. Prior to 1.6.11, and in 1.6.14 and later when invitation IDs can be obtained outside the invited mailbox and requireEmailVerificationOnInvitation: true is not enabled, the organization plugin's acceptInvitation, rejectInvitation, getInvitation, and listUserInvitations recipient endpoints use session.user.email and an invitation ID without sufficient verified-email ownership proof, allowing a user with an unverified session for the invited email address to accept an organization invitation after obtaining the invitation ID. This issue is fixed for the original default behavior in version 1.6.11, while 1.6.14 restored compatibility for built-in opaque invitation IDs and leaves affected configurations requiring secure options.
CVE-2026-53512 Crítica · 9.1 CWE-287 15/07/2026
Better Auth: OAuth refresh-token replay via missing client authentication on oidc-provider and mcp plugins
Better Auth is an authentication and authorization library for TypeScript. Prior to 1.6.11, the legacy oidcProvider and mcp plugins expose OAuth token endpoints whose refresh_token grant authenticates only possession of the bound refreshToken row and matching client_id, without verifying the confidential client's client_secret, allowing an attacker with a valid refresh_token to mint access tokens and rotated refresh tokens through /api/auth/oauth2/token or /api/auth/mcp/token. The @better-auth/oauth-provider package is not affected. This issue is fixed in version 1.6.11.
CVE-2026-47159 Média · 6.9 CWE-287 15/07/2026
Vaultwarden: Authentication Flow Information Disclosure in SSO Discovery Allows Organization Enumeration and Pre-Validation Token Exposure
Vaultwarden is a Bitwarden-compatible server written in Rust. Prior to 1.36.0, Vaultwarden's SSO discovery and pre-validation flow returned organization-related SSO metadata including organizationIdentifier values for arbitrary email addresses and allowed a valid pre-validation JWT to be obtained with only the discovered identifier, enabling SSO-enabled organization enumeration and authentication workflow abuse. This issue is fixed in version 1.36.0.
CVE-2026-44986 Crítica · 9.9 CWE-287 15/07/2026
Penpot: Pre-authenticated account takeover via team-invitation token + prepare-register-profile
Penpot is an open-source design tool for design and code collaboration. Prior to 2.14.5, Penpot exposed teams_invitations.clj invitation tokens from create-team-invitations, embedded an existing profile id in auth.clj prepare-register-profile, and had auth.clj register-profile issue a session based on the invitation email match without password verification, allowing a registered user to take over any non-blocked profile. This issue is fixed in version 2.14.5.
CVE-2026-61740 Crítica · 9.3 CWE-287 15/07/2026
LightRAG: Authentication bypass: hardcoded DEFAULT_TOKEN_SECRET and public /auth-status defeat LIGHTRAG_API_KEY protection
LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.4, when LightRAG is deployed with LIGHTRAG_API_KEY set but AUTH_ACCOUNTS unset, X-API-Key protection can be bypassed because lightrag/api/auth.py falls back to a hardcoded DEFAULT_TOKEN_SECRET, /auth-status and /login can mint guest JWTs, and combined_dependency in lightrag/api/utils_api.py accepts a valid guest token before checking the API key. A remote unauthenticated attacker can call endpoints guarded by combined_auth, including document read, upload, deletion, graph mutation, and query endpoints. This vulnerability is fixed in 1.5.4.
CVE-2026-61436 Alta · 8.6 CWE-287 15/07/2026
PraisonAI before 4.6.78 Missing Webhook Signature Verification
PraisonAI before 4.6.78 fails to verify Svix webhook signatures in AgentMail webhook mode, allowing unauthenticated attackers to forge message.received events. Attackers can send crafted JSON payloads to the webhook endpoint to invoke configured agents with arbitrary sender addresses and message content.
CVE-2026-61435 Alta · 8.2 CWE-287 15/07/2026
PraisonAI before 4.6.78 Authentication Bypass via Host Header Spoofing
PraisonAI before 4.6.78 contains an authentication bypass in the Call API agent invocation endpoints (src/praisonai/praisonai/api/agent_invoke.py) when PRAISONAI_CALL_AUTH=disabled is configured. The safeguard intended to restrict the disabled-auth opt-out to localhost binding derives the bind host from request.url.hostname, which is taken from the client-controlled HTTP Host header. A remote, unauthenticated attacker who can reach the service over the network can send a spoofed 'Host: 127.0.0.1' header to bypass the localhost-only restriction and list (GET /api/v1/agents) and invoke (POST /api/v1/agents/{agent_id}/invoke) registered agents without authentication.
CVE-2026-56353 Média · 4.8 CWE-287 15/07/2026
n8n - Authentication Bypass in Chat Trigger Node
n8n contains an authentication bypass in the Chat Trigger node when configured with n8n User Auth (a non-default configuration). In affected releases — before 1.123.22, the 2.0.0 through 2.9.2 line, and 2.10.0 — the authentication check on the Chat Trigger webhook endpoint can be circumvented, allowing access without valid credentials. Fixed in 1.123.22, 2.9.3, and 2.10.1.
