This vulnerability in Red Hat Quay 3 arises from insufficient session expiration controls during password re-verification for sensitive operations. The re-authentication prompt can be bypassed, enabling users with expired sessions or attackers with access to idle authenticated sessions to execute privileged actions such as token generation or robot account creation without providing valid credentials. The vulnerability is rated medium severity with a CVSS 3.1 base score of 5.4 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N). No patch or official remediation guidance is currently provided in the Red Hat advisory.

The vulnerability allows unauthorized execution of sensitive operations despite session timeout or invalid credential prompts, potentially leading to privilege escalation within Red Hat Quay 3 environments. Confidentiality and integrity impacts are low, as indicated by the CVSS vector, and availability is not affected. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-6848 for current remediation guidance. Until an official fix is available, restrict access to authenticated sessions and consider additional monitoring or session management controls to mitigate risk.
