Description (CNA)
SillyTavern 1.12.13 through 1.19.0 contains a denial of service vulnerability that allows unauthenticated remote attackers to exhaust resources because body-parser middleware runs before authentication and whitelist checks. Attackers can send large or compressed JSON or urlencoded bodies up to 500 MB, optionally in parallel, to exhaust memory and CPU and deny service.
