CVE-2026-115754 is fixed in node-serialize-javascript on 1 platform by DEBIAN-CVE-2026-115754 (version 7.1.4+~5.0.4-1), released October 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
serialize-javascript from 7.0.1 before 7.1.3 contains a cross-site scripting vulnerability that allows attackers to break out of HTML script elements by ending serialized function source text with an unescaped </script. Attackers controlling a function's source via a spoofed toString() can combine surrounding output delimiters and later values to inject live markup such as img onerror handlers.
