Prior to 1.0.0, svg-sanitizer's isHrefSafeValue() validates an SVG href after XML DTD entity expansion, but saveXML() serializes the original entity reference after removing the DTD declaration. A crafted entity such as Tab can appear to the sanitizer as a safe fragment prefix while HTML5 Named Character Reference resolution during inline HTML rendering later converts the surviving reference to whitespace, exposing a javascript: URL. When an application embeds the sanitized SVG inline, a user who activates the link can cause script to execute in the embedding page's origin. This issue is fixed in version 1.0.0.","state":0,"publishedAt":"2026-10-08T18:06:14.107+00:00","modifiedAt":"2026-10-09T15:14:45.596+00:00","affected":[{"ecosystem":"Vendor product","name":"svg-sanitizer","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"darylldoyle\",\n                    \"product\": \"svg-sanitizer\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/darylldoyle/svg-sanitizer/security/advisories/GHSA-9rjx-3jch-6vjf","https://github.com/darylldoyle/svg-sanitizer/commit/23877db7e76f1e1df5c3e65ab30239219c3d2867","https://github.com/darylldoyle/svg-sanitizer/releases/tag/1.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107380","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107380","identifiers":["CVE-2026-107380"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
