What is CVE-2026-6848?

A flaw present in Red Hat Quay permits a user to bypass required password re-verification for conducting sensitive operations such as token generation and robot account creation. This vulnerability arises when a session has timed out, allowing an attacker who has access to an idle authenticated session to execute privileged actions without proper credential verification. Even though the user interface indicates an invalid credential error, the vulnerability undermines the authentication process, leading to unauthorized executions.
