CVE-2026-71555 Aug 06, 22:18 MEDIUM PATCH This Month

Reverse tabnabbing in PILOS versions 2.1.0 through 4.14.1 exposes authenticated users to session hijacking via phishing by omitting the Cross-Origin-Opener-Policy (COOP) response header on pages that open links in new browser tabs. When an authenticated user clicks a target="_blank" link within PILOS, the newly opened page retains a live window.opener reference to the original PILOS tab, allowing the destination page to silently redirect that tab to an attacker-controlled site mimicking PILOS login. No public exploit has been identified at time of analysis, and the vendor-confirmed fix is available in v4.14.1.
