SCA: security update for joserfc (GHSA-wphv-vfrh-23q5)

medium Tenable Self-Hosted Container Security Plugin ID 444071

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption
 (JOSE) standards. In versions 1.3.4 through 1.6.5, joserfc accepts oversized RFC7797 b64=false JWS
 payloads without applying JWSRegistry.max_payload_length, which can lead to resource exhaustion. The
 normal JWS compact and flattened JSON paths reject payloads above the configured payload-size limit with
 ExceededSizeError. The RFC7797 unencoded payload paths do not make the same check. A valid b64=false
 compact or flattened JSON JWS can therefore deserialize successfully with a payload larger than
 JWSRegistry.max_payload_length. Applications that accept lower-trust JWS values and rely on joserfc to
 reject oversized token content during verification have a moderate availability risk. This issue has been
 fixed in version 1.6.7. (CVE-2026-48990)

Solution

Update the joserfc library and its related packages to version 1.6.7 or later.
