Echo: pyjwt: security update to 2.13.0

medium Tenable Self-Hosted Container Security Plugin ID 474337

Description

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

 - PyJWT is a Python implementation of JSON Web Token standards. From 2.11.0 through 2.13.0, PyJWT's
 PyJWT._merge_options() method can modify a caller-supplied mutable options mapping when verify_signature
 is false. If an application reuses that same mapping for a later decode() or decode_complete() call and
 changes verify_signature to true, the mapping can retain false values for expiration, not-before, issued-
 at, audience, issuer, subject, and JWT ID checks. A signed token with invalid registered claims can then
 be accepted without disabling signature verification, but applications that create a fresh options mapping
 for each call are not affected. (CVE-2026-103001)

Solution

Update the pyjwt library and its related packages to version 2.13.0 or later.
