    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing
    IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to
    individual teams, while automation developers retain the freedom to write tasks that leverage existing
    knowledge without the overhead. Ansible Automation Platform makes it possible for users across an
    organization to share, vet, and manage automation content by means of a simple, powerful, and agentless
    language.

    Security Fix(es):

    * automation-controller: PyJWT: Authentication bypass due to forged JSON Web Tokens (CVE-2026-48526)
    * automation-eda-controller: ExternalEventStreamViewSet trusts Subject header without validation and leaks
    expected DN (CVE-2026-12383)
    * automation-gateway-proxy: Go net package: Denial of Service via long CNAME response in LookupCNAME
    (CVE-2026-33811)

    * python3.12-daphne: daphne: Denial of Service via excessive WebSocket message size (CVE-2026-44545)
    * python3.12-pillow: Denial of Service via crafted PCF font data (CVE-2026-54059)
    * python3.12-pillow: Denial of Service via excessive memory allocation when processing font files
    (CVE-2026-54060)
    * python3.12-pillow: Denial of Service via crafted BDF font file (CVE-2026-55379)
    * python3.12-pillow: Denial of Service via crafted GD 2.x image file (CVE-2026-55380)
    * python3.12-pillow: Native heap out-of-bounds write (CVE-2026-59197)
    * python3.12-pyasn1: Denial of Service via crafted ASN.1 REAL values (CVE-2026-59885)
