GO-2026-5989 Unauthenticated OIDC login in nebula-mesh allows unbounded memory allocation in github.com/forgekeep/nebula-mesh

When OIDC is enabled, the login endpoint is reachable without authentication and is registered outside the rate-limited auth routes. Every request creates a fresh random OIDC state value and stores it in an in-memory map. An unauthenticated remote client can grow the state storage, bounded by...

GHSA-M3CX-MWPG-32JG nebula-mesh: Unauthenticated OIDC login endpoint allocates unbounded in-memory state entries without rate limiting

Summary When OIDC is enabled, GET /ui/oidc/login is reachable without authentication and is registered outside the Web UI rate-limited auth routes. Every request creates a fresh random OIDC state value and stores it in an in-memory map for 10m. Expired states are swept lazily, but there is no rat...

Name of the Vulnerable Software and Affected Versions Nebula-mesh versions 0.2.0 through 0.3.8 Description When OIDC is enabled, the application is susceptible to a denial of service via memory exhaustion. An unauthenticated remote client can repeatedly send requests to the GET /ui/oidc/login...

CVE-2026-55205 Hermes WebUI < 0.51.468 - Resource Exhaustion via Unauthenticated OAuth Flow Endpoint

Hermes WebUI before 0.51.468 contains a resource exhaustion vulnerability in the unauthenticated POST /api/onboarding/oauth/start endpoint that allows unbounded accumulation of in-memory flow state and daemon threads. Attackers can send repeated or concurrent requests to exhaust server memory and...

CVE-2026-44564

Open WebUI (self-hosted offline AI platform) contains a vulnerability in the ydoc:document:update Socket.IO handler that allows read-only users to modify in-memory Yjs documents. The handler validates room membership but does not verify write permission, and read-only users join the document room...

openssl-encrypt: TOTP rate limiter is in-memory only — not shared across workers, lost on restart

Severity: HIGH Summary The TOTP brute-force rate limiter in opensslencryptserver/modules/pepper/totp.py at lines 47-98 uses an in-memory defaultdictlist as a class variable. Affected Code python class TOTPRateLimiter: def initself, ...: self.attempts: Dictstr, Listdatetime = defaultdictlist...

Incorrect Authorization

Overview Affected versions of this package are vulnerable to Incorrect Authorization via the debug/pprof endpoints. An attacker can access sensitive server internals, including runtime profiling data and in-memory application state, and trigger CPU-intensive profiling operations that could impact...
