Doc Text:
A flaw was found in Revive Adserver. An authenticated user with manager privileges can bypass authorization controls by modifying the submitted agency identifier parameter when configuring delivery rules. Because the application improperly trusts the user-supplied identifier, this flaw allows an attacker to create delivery rule sets within another agency's account, leading to unauthorized cross-account configuration changes.

Description OSIDB Bzimport 2026-11-11 17:41:29 UTC 
An authorization bypass in channel-edit.php in Revive Adserver 6.0.8 and earlier allows an authenticated manager to create a delivery rule set belonging to another agency by changing the submitted agencyid parameter. The server trusts the submitted agency identifier when inserting the new rule set, allowing unauthorized creation of objects in another agency's account. The issue is fixed in Revive Adserver 6.0.9 by obtaining the agency identifier from the authenticated account rather than submitted form data and removing the agency identifier from the form's hidden fields.
