CVE-2026-74245 is a medium-severity flaw (CVSS 5.9) affecting openshift update service, quay. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in Red Hat Quay's exported logs feature. An unauthenticated attacker with a valid file ID could download exported action logs without proper authorization. While file IDs are complex, they can be intercepted from plaintext email or webhook callbacks. This vulnerability leads to information disclosure, potentially exposing sensitive data such as usernames, email addresses, IP addresses, and action-specific metadata.
