cyrus-imapd: Cyrus IMAP: Unauthorized access due to URLAUTH not honoring revoked authorizer access
An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. URLAUTH does not honor revoked authorizer access. A URLAUTH URL minted while the authorizer had access continued to work after that access was revoked.
A flaw was found in Cyrus IMAP. The URLAUTH mechanism in Cyrus IMAP through version 3.12.2 does not properly revoke access for an authorizer. This allows a previously authorized user to retain access via a URLAUTH URL, even after their authorization has been revoked, potentially leading to unauthorized information disclosure.
