CVE-2024-54226Network attack vector

Stored XSS via forged administrator request

Published Dec 9, 2024 · Updated Apr 28, 2026

Cross-site request forgery in Karl Kiesinger Country Blocker 3.2 and earlier allows remote attackers to store malicious scripts. Missing or incorrect nonce validation on the settings-update function accepts a forged administrator request and writes attacker-supplied script content. Exploitation requires an authenticated site administrator to follow a malicious link or visit a crafted page, after which stored scripts run in affected site contexts.
