CVE-2026-50744: Revive-Adserver Revive Adserver

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Revive-Adserver Revive Adserver: before 6.0.8 (fixed in 6.0.8)
