CVE-2026-25119 High · 7.7 CWE-290 Jun 24, 2026

Gogs: Authentication Bypass via Unvalidated Reverse Proxy Headers

Gogs is an open source self-hosted Git service. Prior to 0.14.3, when ENABLE_REVERSE_PROXY_AUTHENTICATION is enabled, Gogs accepts the configured authentication header (default: X-WEBAUTH-USER) directly from client requests without validating that the request originated from a trusted reverse proxy. Any remote attacker who can reach the Gogs service can forge this header to impersonate any user or trigger automatic account creation, completely bypassing authentication. This vulnerability is fixed in 0.14.3.

CVE-2026-47381 Medium · 6.9 CWE-290 Jun 23, 2026

NocoDB: Cross-Workspace Integration Use in Connection Test

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, a user in one workspace could exercise another workspace's integration through the testConnection endpoint by supplying its ID, because the integration was fetched in a bypass scope and the caller's permission check matched any base in any workspace. This vulnerability is fixed in 2026.05.1.

CVE-2026-49468 Critical · 9.8 Public exploit CWE-290 Jun 22, 2026

LiteLLM Proxy: authentication bypass via Host header spoofing (CVE-2026-49468)

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.84.0, a Host-header parsing flaw in the LiteLLM proxy could, under specific conditions, allow unauthenticated access to protected management routes. The auth layer derived the effective route from request.url.path in litellm/proxy/auth/auth_utils.py::get_request_route(), which Starlette reconstructs from the Host header. A crafted Host could therefore make the auth gate evaluate a different route from the one FastAPI dispatched. This vulnerability is fixed in 1.84.0.

Woodpecker gRPC agent_id metadata can be spoofed- cross-tenant agent impersonation

Woodpecker is a CI/CD engine. Starting in version 3.0.0 and prior to version 3.14.1, a vulnerability in Woodpecker CI's gRPC layer allowed any authenticated agent to impersonate any other agent on the same server by injecting a forged `agent_id` value into outgoing gRPC metadata. The server correctly verified the JWT token but then discarded the verified agent identity in favor of the client-supplied value. Version 3.14.1 patches the issue. As a workaround, disable org agents (`WOODPECKER_DISABLE_USER_AGENT_REGISTRATION=true`) and delete existing ones.

CVE-2026-55202 High · 8.2 CWE-290 Jun 17, 2026

Tinyproxy - Stathost Detection Bypass via Host Header Manipulation

Tinyproxy through 1.11.3, fixed in commit 09312a1, fails to properly validate the Host header during stathost detection, allowing unauthenticated attackers to access the stats page by injecting a matching Host header or bypass detection via port manipulation. Remote attackers can trigger unauthorized access to internal proxy statistics or misroute requests as transparent proxy connections to circumvent access controls.

ThingsBoard v4.3.0.1 is vulnerable to an authentication bypass during the OAuth…

ThingsBoard v4.3.0.1 is vulnerable to an authentication bypass during the OAuth authorization code exchange. The application improperly trusts user-supplied identity data within the user parameter of the /login/oauth2/code/ endpoint. By manipulating the email address in this JSON object, a remote attacker can bypass authentication and gain full access to any existing user account on the platform without possessing the target user's credentials. This results in a complete account takeover.

CVE-2026-49757 Critical · 9.2 CWE-290 Jun 15, 2026

OAuth2/OIDC account takeover in AshAuthentication via email-based user matching

Authentication Bypass by Spoofing vulnerability in team-alembic AshAuthentication allows account takeover of local users via OAuth2/OIDC sign-in. AshAuthentication's OAuth2 and OIDC family strategies matched the local user by email address (an upsert on the email field, or a user-defined sign-in filter) rather than by the OpenID Connect iss/sub claim combination. Per OpenID Connect Core §5.7, only iss/sub uniquely and stably identifies an end-user; other claims, including email, MUST NOT be used as unique identifiers. A provider login presenting a victim's email, including an unverified email, a reused email, or an account with email_verified: false, resolved to and signed in as the victim's existing local account. An unauthenticated attacker who can register an account on any accepted OAuth provider with the victim's email (or who benefits from provider-side email reuse or reclamation) obtains the victim's full local privileges. The fix resolves users by the (strategy, sub) identity stored in a user identity resource, and only links a new sub to an existing local account by email when the provider's email_verified claim is trusted (trust_email_verified?). This issue affects ash_authentication from 0.1.0 before 4.14.0 and from 5.0.0-rc.0 before 5.0.0-rc.10.

CVE-2026-34025 Medium · 5.3 CWE-290 Jun 15, 2026

IP restriction bypass in Wertheim SafeController Software allows logins from unauthorized network locations

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains an IP restriction bypass vulnerability in the login process. The application restricts user logins based on the IP address associated with a branch location, but the client IP address is derived from the HTTP X-Forwarded-For header when that header is present. An attacker with valid branch user credentials can manipulate the X-Forwarded-For header during login to spoof the expected branch IP address and obtain a valid authenticated session from an unauthorized network location.
