CVE-2026-108558
Published:November 11, 2026
Updated:November 12, 2026
A reflected cross-site scripting vulnerability in the conversion-statistics pages of Revive Adserver 6.0.8 and earlier allows an unauthenticated attacker to execute JavaScript in an authenticated user's browser by persuading them to visit a crafted URL. An incorrect ownership check validates the advertiser identifier instead of the supplied website identifier, allowing malicious website input to reach HTML output without appropriate encoding. A related output issue affects the hour parameter. The issue is fixed in Revive Adserver 6.0.9 by validating the correct website identifier and normalising the hour parameter before formatting.
