## Technical details

Revive Adserver (up to version 6.0.7) is vulnerable to a bypass of the fix for CVE-2026-34916, leading to improper control of generation of code (CWE-94). The vulnerability exists because the previous security patch can be circumvented by providing a disallowed but valid plugin identifier as the 'type' parameter, or by utilizing the 'ox.setChannelTargeting' XML-RPC API method. An attacker with low-privileged network access can exploit this to achieve remote code execution (RCE). The vulnerability was reported via HackerOne and affects versions up to and including 6.0.7.

## Affected products
