Reflected XSS via undisclosed input reflection

Published Mar 25, 2026 · Updated Mar 25, 2026

Reflected XSS in G5Theme Wolverine Framework 1.9 and earlier allows remote attackers to execute script via a crafted web request. Patchstack has not disclosed the affected request parameter or code path, identifying only improper neutralization of reflected input during page generation. Exploitation is unauthenticated but requires a privileged user to open a crafted link or page, causing attacker-supplied script to run in that user's browser session.
