CVE-2024-11277Network attack vector

Reflected XSS via unescaped request URL output

Published Nov 20, 2024 · Updated Apr 8, 2026

Reflected XSS in Aaron J 404 Solution 2.35.19 and earlier allows remote attackers to run scripts through crafted 404 request URLs. Published sources identify the vulnerable locus only as URL handling and do not disclose the function; that path emits attacker-controlled URL data without sufficient sanitization or output escaping. Execution requires a user to follow a crafted link; the injected script then runs in that user's browser context, allowing page data to be read or altered.
