GFI KerioConnect < 10.0.9p2 XSS via Link Auto-Formatter

Published Oct 28, 2026 · Updated Oct 28, 2026 · Assigned by VulnCheck

Description

GFI KerioConnect (Kerio Connect) before 10.0.9 Patch 2 contains a cross-site scripting vulnerability in the Webmail component that allows a remote attacker to spoof link targets or inject HTML into a message as rendered in a victim's authenticated Webmail session by sending a crafted email whose text is already inside a link. Attackers can exploit the link auto-formatter's re-processing of already-linked text, using quote characters to break out of the href attribute and inject attacker-controlled markup to execute script in the victim's session.
