  "title": "Unauthenticated request-body resource exhaustion in SillyTavern",
  "summary": "SillyTavern versions 1.12.13 through 1.19.0 accept request bodies before authentication and allowlist enforcement. A remote unauthenticated attacker can consume server memory and CPU and disrupt availability by submitting large or compressed requests, especially when the service is reachable over the network.",
  "mitigation": "Do not expose the service directly to untrusted networks; place it behind a reverse proxy or gateway that enforces strict request-size, decompression, rate, and connection limits before requests reach SillyTavern. Restrict access to trusted users and networks until an updated release is available.",
