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 — outputEscape is unset by default). This issue has been fixed in version 10.26.0.","state":0,"publishedAt":"2026-06-17T21:50:24.743+00:00","modifiedAt":"2026-06-18T13:09:26.903+00:00","affected":[{"ecosystem":"Vendor product","name":"liquidjs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"harttle\",\n                    \"product\": \"liquidjs\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 10.26.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/harttle/liquidjs/security/advisories/GHSA-2qv6-9wx5-cwv4","https://github.com/harttle/liquidjs/commit/26ea2856c7a90aec892b98d94a9b7a3e18539045","https://github.com/harttle/liquidjs/releases/tag/v10.26.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-44644","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-44644","identifiers":["CVE-2026-44644"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
