CVE-2026-50744 | BDVDB-2026-343545 Detail

ReviveAdserver

Description#

A bypass to the admin‑only restriction of the XML‑RPC 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.

Impact#

Per CVSS v3.0: confidentiality impact low, integrity impact none, availability impact none. Attack vector: network.
