Serialize JavaScript: Cross-site scripting (XSS) via unescaped </script> in serialized function bodies

Impact serialize-javascript escapes its output so it is safe to embed inside a element. In 7.1.1 that guarantee does not hold for function values: a crafted function body can carry a literal, unescaped into the output, terminating the script element early so the remainder is parsed as HTML...

CVE-2026-97711 Serialize JavaScript: Cross-site scripting (XSS) via unescaped </script> in serialized function bodies

Serialize JavaScript serializes JavaScript values to a superset of JSON that includes regular expressions and functions. From 7.1.1 until 7.1.2, function values serialized by serialize-javascript are not fully protected against script-closing tags in attacker-influenced function source because...

CVE-2026-97711

The serialize-javascript library is vulnerable to cross-site scripting (XSS) in versions 7.1.1 through 7.1.2 . The root cause is that the SCRIPT_CLOSE_REGEXP can consume a second closing tag within a single match, failing to fully protect serialized function values against script-closing tags. If...
