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. Prior to 1.7.6, joserfc compact JWS deserialization calls bytes.split() before enforcing
    the existing aggregate segment-size limits. When attacker-controlled compact serialization bytes reach
    deserialize_compact(), the split creates copies of the header, payload, and signature segments before
    ExceededSizeError rejects them, causing an additional allocation approximately proportional to the
    supplied token. Requests that exhaust available process memory can therefore cause an availability failure
    even though signature verification fails. This issue is fixed in version 1.7.6. (CVE-2026-119284)

The remote Fedora 46 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-6527dc724a advisory.

    Automatic update for python-joserfc-1.8.0-1.fc46.
