CVE-2026-85725 LightRAG: Plaintext Passwords Compared Without Constant-Time Function

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.5, verifypassword in lightrag/api/passwords.py compares plaintext AUTHACCOUNTS password values with Python's == operator. The comparison can return after the first mismatching byte, creating response-time differences...

CVE-2026-85725

Prior to version 1.5.5 , LightRAG is vulnerable to a timing attack in the verify_password function within lightrag/api/passwords.py. The application uses Python's == operator to compare plaintext password values in AUTH_ACCOUNTS, which short-circuits on the first mismatching byte. A network attac...

CVE-2026-88010 Traefik: BasicAuth singleflight coalescing reintroduces an unauthenticated username-enumeration timing oracle

Traefik is an open source HTTP reverse proxy and load balancer. From 3.6.11 until 3.7.13, checkPassword in pkg/middlewares/auth/basicauth.go constructs the BasicAuth singleflight key from the submitted password and stored secret. Concurrent requests for absent usernames therefore coalesce on one...

CVE-2026-88010

Traefik (open source HTTP reverse proxy and load balancer) versions 3.6.11 through before 3.7.13 contain an unauthenticated username-enumeration timing oracle in the BasicAuth middleware. The checkPassword function in pkg/middlewares/auth/basic_auth.go constructs the singleflight key from the sub...

CVE-2026-77987: Server-Side Request Forgery (SSRF)

A server-side request forgery SSRF vulnerability was identified in the notebook viewer of GitHub Enterprise Server. The notebook viewer validated the scheme and host of a user-supplied URL but did not validate the port, allowing requests to be directed to internal services listening on other port...

CVE-2026-85725: Observable Timing Discrepancy

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.5, verifypassword in lightrag/api/passwords.py compares plaintext AUTHACCOUNTS password values with Python's == operator. The comparison can return after the first mismatching byte, creating response-time differences...

PT-2026-96824

Name of the Vulnerable Software and Affected Versions LightRAG versions prior to 1.5.5 Description When plaintext passwords are stored in AUTH ACCOUNTS, the verify password function in lightrag/api/passwords.py uses the Python == operator for comparison. This operator is not constant-time and...

PT-2026-97052

Name of the Vulnerable Software and Affected Versions GitHub Enterprise Server versions 3.17 through 3.22 Description A server-side request forgery SSRF issue exists in the notebook viewer. While the system validates the scheme and host of a user-supplied URL, it fails to validate the port. This...

CVE-2026-77582 Tinyauth: User enumeration attack by timing oracle

Tinyauth is an authentication and authorization server. Prior to 5.1.0, Tinyauth exposes a remotely observable timing difference between authentication attempts for existing and nonexistent local usernames. internal/controller/usercontroller.go loginHandler and...
