CVE-2026-78850

medium

Description

An issue in Matomo v.5.11.2 allows a remote attacker to obtain sensitive information via the SiteContentDetector / SitesManager component. NOTE: the Supplier disputes the relevance of this report because the site administrator is a trusted party, and would not plausibly set main_url to a URL that offers additional information to an adversary.
