{"id":"CVE-2026-107380","published":"2026-10-08T18:17:23.787","lastModified":"2026-10-09T16:17:22.457","description":"savg-sanitizer is a PHP SVG/XML sanitizer. 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.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/darylldoyle/svg-sanitizer/commit/23877db7e76f1e1df5c3e65ab30239219c3d2867","tags":[]},{"url":"https://github.com/darylldoyle/svg-sanitizer/releases/tag/1.0.0","tags":[]},{"url":"https://github.com/darylldoyle/svg-sanitizer/security/advisories/GHSA-9rjx-3jch-6vjf","tags":[]}],"exploitRefs":[{"url":"https://github.com/darylldoyle/svg-sanitizer/commit/23877db7e76f1e1df5c3e65ab30239219c3d2867","tags":[]},{"url":"https://github.com/darylldoyle/svg-sanitizer/releases/tag/1.0.0","tags":[]},{"url":"https://github.com/darylldoyle/svg-sanitizer/security/advisories/GHSA-9rjx-3jch-6vjf","tags":[]}],"hasPoc":true,"ai":null}
