CVE-2023-45771Network attack vector

Reflected XSS via undisclosed request handling

Published Mar 26, 2024 · Updated Apr 28, 2026

Reflected cross-site scripting in Teqlog Contact Form With Captcha 1.6.8 and earlier allows remote attackers to run script via crafted requests. The CNA and linked advisory do not disclose the affected parameter or code path, and the linked advisory currently labels the flaw as CSRF rather than explaining the recorded XSS mechanism. Exploitation requires a user to follow a crafted link or visit an attacker-controlled page, after which script runs in the affected site's browser origin.
