NetLicensing-MCP: Unauthenticated Use of Server-Side NetLicensing API Key in HTTP Mode

Unauthenticated Use of Server-Side NetLicensing API Key in HTTP Mode Summary When netlicensing-mcp is run in HTTP transport mode, the ApiKeyMiddleware fails to enforce authentication: requests that carry no client API key are unconditionally forwarded to the next handler server.py:1427. The...

GHSA-QF34-295C-26V8 Woodpecker: Privilege escalation via unrestricted serviceAccountName in the Kubernetes backend

Impact A privilege escalation vulnerability affects Woodpecker instances using the Kubernetes backend. The pipeline option backendoptions.kubernetes.serviceAccountName was passed directly to the pod spec without any admin gating. Who is impacted: any operator running the Kubernetes backend. Any...

Nebula-mesh allows non-admin operators to disable webhook SSRF protection via `allow_private`

Summary Non-admin operators role user can set allowprivate: true on their own managed webhook subscription POST/PATCH /api/v1/webhook-subscriptions. No admin check exists on this field. At delivery time, allowprivate switches the dispatcher to an unguarded HTTP client, bypassing the...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the allowprivate process. An attacker can access internal network resources and obtain sensitive information by setting the allowprivate parameter to true in webhook subscriptions, which disables SSRF...

nebula-mesh: Certificate revocation is never enforced at the mesh

Summary nebula-mesh revokes a host by adding its certificate fingerprint to a per-CA blocklist and shipping that list to every other agent on each poll. Slack's Nebula enforces certificate revocation ONLY through the pki.blocklist list in config.yml no CRL/OCSP. The project's own code states this...

nebula-mesh: Web UI host creation ignores configured enrollment token TTL and mints 24-hour bearer enrollment tokens

Summary The nebula-mgmt Web UI host-creation path ignores both the server-wide enrollmenttokenttl security setting and per-network networkconfig.enrollmenttokenttl overrides. API host creation and token-regeneration paths use the configured TTL resolver, but POST /ui/hosts hardcodes now.Add24...

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...
