Vulnerability from github – Published: 2026-06-12 00:31 – Updated: 2026-06-12 00:31

Details

Idira Identity Browser Extension (Chrome, Firefox, and Edge builds) versions prior to 26.8.1 exhibit an origin validation flaw within its internal web-page verification routines. If an authenticated user navigates to a specially crafted webpage, this interaction could potentially allow a remote attacker to trigger unauthorized application interaction or execution parameters within the context of that authenticated browser session. CyberArk Security Bulletin: CA26-21

Severity

8.4 (High)
