Description

Red Hat has released a new satellite/iop-host-inventory-rhel9 container image for Red Hat Lightspeed in Satellite, which analyzes system health and configuration locally. The advisory references multiple CVEs including CVE-2026-63374 but does not provide specific details about this CVE's vulnerability or impact. One related CVE (CVE-2026-102267) involves a flaw in PyJWT where improper validation of HTTP redirects during JSON Web Key Set retrieval can allow attackers to supply forged cryptographic keys or intercept sensitive headers, potentially compromising token validation and authentication. No fixes are currently available for this PyJWT issue, and mitigation options are limited. The advisory does not explicitly state affected versions or patch availability for the container image or the other CVEs mentioned.
