Doc Text:
A flaw was found in Revive Adserver. An unauthenticated remote attacker could exploit this stored cross-site scripting (XSS) vulnerability by convincing a user to follow a crafted report link and reauthenticate. Because date-selection controls fail to properly sanitize and encode user-supplied values before saving them in the session, arbitrary JavaScript code can execute within the context of the victim's browser on initial and subsequent report views.

Description OSIDB Bzimport 2026-11-11 17:41:25 UTC 
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.
