CVE-2025-62706 (CNNVD-202510-2797)
中文标题:
Authlib 安全漏洞
英文标题:
Authlib : JWE zip=DEF decompression bomb enables DoS
漏洞描述
中文描述:
Authlib是Authlib开源的一个构建 OAuth 和 OpenID Connect 服务器的终极 Python 库。 Authlib 1.6.5之前版本存在安全漏洞,该漏洞源于JWE zip=DEF路径执行无限制DEFLATE解压缩,可能导致内存和CPU耗尽,造成拒绝服务攻击。
英文描述:
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.5, 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. This issue has been patched in version 1.6.5. Workarounds for this issue involve rejecting or stripping zip=DEF for inbound JWEs at the application boundary, forking and add a bounded decompression guard via decompressobj().decompress(data, MAX_SIZE)) and returning an error when output exceeds a safe limit, or enforcing strict maximum token sizes and fail fast on oversized inputs; combine with rate limiting.
