CVE-2026-108561
Revive Adserver Stored Cross-Site Scripting Vulnerability
Description
A stored cross-site scripting vulnerability in the report date-selection controls of Revive Adserver 6.0.8 and earlier allows an unauthenticated attacker to execute JavaScript in a victim's browser by persuading them to follow a crafted report URL and complete normal reauthentication. An attacker-controlled period_preset value can be saved in the victim's session and inserted into JavaScript without appropriate encoding. The payload can execute on the initial report view and subsequent report views using the stored defaults. The issue is fixed in Revive Adserver 6.0.9 by applying JSON encoding appropriate for the JavaScript context to date-selection values.
