Versions 10.25.7 and below are vulnerable to XSS through a flaw in the strip_html filter logic. The strip_html filter is intended to remove HTML tags from a string before rendering, and is widely used as an XSS sanitizer. The implementation uses a regex whose catch-all branch (<.*?>) does not match line terminators, so any HTML tag containing a \\n or \\r character passes through unmodified. An attacker who can place a newline inside a tag (e.g. <img\\nsrc=x\\nonerror=alert(1)>) bypasses sanitization entirely, since browsers treat newlines as whitespace within a tag and execute the resulting onerror/onload/etc. handler. Exploitation is possible for applications that both render attacker-controlled strings via {{ x | strip_html }} to defend against HTML injection and do not separately HTML-escape that output (default behavior \u2014 outputEscape is unset by default). This issue has been fixed in version 10.26.0."}], "lastModified": "2026-06-22T18:27:30.807", "sourceIdentifier": "security-advisories@github.com"}
