CVE-2026-57246

When dealing with abnormally constructed objects, there is a lack of argument validation; JavaScript triggers signature verification, but the signature plugin does not perform validation when copying the abnormal string, causing the application to crash...

PYSEC-2026-1200 Authlib: JWS/JWT accepts unknown crit headers (RFC violation → possible authz bypass)

Summary Authlib’s JWS verification accepts tokens that declare unknown critical header parameters crit, violating RFC 7515 “must‑understand” semantics. An attacker can craft a signed token with a critical header for example, bork or cnf that strict verifiers reject but Authlib accepts. In...

PYSEC-2026-1922 SignXML's signature verification with HMAC is vulnerable to a timing attack

When verifying signatures with X509 certificate validation turned off and HMAC shared secret set signxml.XMLVerifier.verifyrequirex509=False, hmackey=..., prior versions of SignXML are vulnerable to a potential timing attack. The verifier may leak information about the correct HMAC when comparing...

PYSEC-2026-1921 SignXML's signature verification with HMAC is vulnerable to an algorithm confusion attack

When verifying signatures with X509 certificate validation turned off and HMAC shared secret set signxml.XMLVerifier.verifyrequirex509=False, hmackey=..., prior versions of SignXML are vulnerable to a potential algorithm confusion attack. Unless the user explicitly limits the expected signature...

PYSEC-2026-827 jwcrypto token substitution can lead to authentication bypass

The JWT code can auto-detect the type of token being provided, and this can lead the application to incorrect conclusions about the trustworthiness of the token. Quoting the private disclosure we received : "Under certain circumstances, it is possible to substitute a .. signed JWS with a JWE that...
