python-pyjwt: PyJWT: Denial of Service via processing of crafted detached JWS tokens

A flaw was found in PyJWT. A remote attacker can exploit this by supplying an arbitrarily large Base64URL payload segment when verifying detached JSON Web Signature JWS tokens using the unencoded-payload option. This forces excessive CPU work and memory allocations, leading to a Denial of Service...

PyJWT: Unauthenticated DoS via unbounded Base64URL decoding of unused payload segment in b64=false detached JWS

!NOTE Practical impact depends on whether request body-size limits are enforced upstream proxy/web-server/framework. Deployments with typical body-size caps ≤2 MB bound the amplifier significantly; deployments accepting larger token inputs are more exposed. When verifying detached JWS tokens usin...
