ReviveAdserver Improper Access Control Vulnerability - CVE-2026-50744
A bypass to the adminonly restriction of the XMLRPC API in Revive Adserver 6.0.7. The API response for the ox.login method returned a session ID cookie in the HTTP headers and although the method correctly returned an error the associated session was not invalidated. As a result the leaked session ID could be used to perform subsequent API calls without restrictions.
