CVE-2026-63464

CVE-2026-63464 affects nebula-mesh , a self-hosted control plane for Slack Nebula mesh VPN, in versions 0.6.0 through before 0.7.2 . The vulnerability is an SSRF that arises because non-admin operators (role user) can set allow_private: true on their own webhook subscription via POST/PATCH /api/v...

CVE-2026-63464 Nebula-mesh allows non-admin operators to disable webhook SSRF protection via `allow_private`

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. From version 0.6.0 to before version 0.7.2, 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...

CVE-2026-61699

nebula-mesh (forgekeep) is a self-hosted control plane for the Slack Nebula mesh VPN. Prior to v0.7.1 , the agent-side poller decodes the per-CA revocation blocklist from the server but discards it — it never writes pki.blocklist into the local config.yml, and the config generator has no field to...

CVE-2026-61699 nebula-mesh: Certificate revocation is never enforced at the mesh

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.7.1, revocation is the only in-band mechanism that isolates a compromised/offboarded host from a Nebula mesh. Because the blocklist never reaches any peer's config.yml, a Blocked host retains full overlay...

CVE-2026-55513

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. In versions 0.3.0 through before 0.5.0 , the POST /ui/hosts Web UI endpoint hardcodes a 24-hour enrollment token expiry instead of using the configured enrollment_token_ttl (server-wide or per-network) resolver that the API pat...

CVE-2026-55513 nebula-mesh: Web UI host creation ignores configured enrollment token TTL and mints 24-hour bearer enrollment tokens

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. From version 0.3.0 to before version 0.5.0, the nebula-mgmt Web UI host-creation path ignores both the server-wide enrollmenttokenttl security setting and per-network networkconfig.enrollmenttokenttl overrides. API host creatio...

CVE-2026-55512

nebula-mesh (self-hosted control plane for Slack Nebula mesh VPN) versions 0.2.0 through before 0.5.0 are vulnerable to uncontrolled resource consumption via the GET /ui/oidc/login endpoint. When OIDC is enabled, this route is registered outside the Web UI rate-limited auth group, so every unauth...

CVE-2026-55512 nebula-mesh: Unauthenticated OIDC login endpoint allocates unbounded in-memory state entries without rate limiting

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. From version 0.2.0 to before version 0.5.0, 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...

CVE-2026-53604 nebula-mesh: CA private key not zeroized on web mobile-bundle error paths

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.3.8, the web handler renderMobileBundle passes the real pki.CAResolver directly into mobilebundle.Build. Inside Build, resolver.LoadByID decrypts the CA's ed25519 private key into a pki.CAManager, but Build...

CVE-2026-53604

nebula-mesh (a self-hosted control plane for Slack Nebula mesh VPN by forgekeep ) is affected by a key-zeroization flaw in its web UI mobile-bundle path. The renderMobileBundle handler passes a decrypted *pki.CAManager containing the CA's ed25519 private key into mobilebundle.Build, which never c...

CVE-2026-53603 nebula-mesh: Operator session tokens stored in plaintext in the database

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.3.8, Operator session tokens are stored in plaintext in the operatorsessions table the token column is the PRIMARY KEY. The session token is a 32-byte random hex value sent directly in a cookie and valid for ...

CVE-2026-53603

nebula-mesh , a self-hosted control plane for Slack Nebula mesh VPN, stored operator session tokens in plaintext in the operator_sessions table (the token column served as the PRIMARY KEY). Each token is a 32-byte random hex value delivered via cookie with a 24-hour validity. Unlike API keys and ...

CVE-2026-53602 nebula-mesh - Host revocation is not durable: blocked/offboarded hosts can regain a valid certificate

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.3.7, two related authorization gaps let a host that should no longer be trusted obtain a fresh, valid Nebula certificate, because nebula-mgmt does not re-evaluate revocation/authorization state at certificate...

CVE-2026-53602 nebula-mesh - Host revocation is not durable: blocked/offboarded hosts can regain a valid certificate

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN.
