Allocation of Resources Without Limits or Throttling

Overview authlib is a library in building OAuth and OpenID Connect servers. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the DeflateZipAlgorithm.decompress function. An attacker can exhaust memory and CPU resources by submitting...

GHSA-G7F3-828F-7H7M Authlib : JWE zip=DEF decompression bomb enables DoS

Summary Authlib’s JWE zip=DEF path performs unbounded DEFLATE decompression. A very small ciphertext can expand into tens or hundreds of megabytes on decrypt, allowing an attacker who can supply decryptable tokens to exhaust memory and CPU and cause denial of service. Details - Affected component...

CVE-2025-61920

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.5, Authlib’s JOSE implementation accepts unbounded JWS/JWT header and signature segments. A remote attacker can craft a token whose base64url‑encoded header or signature spans hundreds of megabytes...

Authlib is vulnerable to Denial of Service via Oversized JOSE Segments

Summary Authlib’s JOSE implementation accepts unbounded JWS/JWT header and signature segments. A remote attacker can craft a token whose base64url‑encoded header or signature spans hundreds of megabytes. During verification, Authlib decodes and parses the full input before it is rejected, driving...
