{"id":"CVE-2023-22461","aliases":["GHSA-h857-2g56-468g"],"url":"https://o3.security/vulnerability/CVE-2023-22461","summary":"sanitize-svg Filter Bypass Allows Cross-Site Scripting (XSS)","details":"The `sanitize-svg` package, a small SVG sanitizer to prevent cross-site scripting attacks, uses a deny-list-pattern to sanitize SVGs to prevent XSS. In doing so, literal `<script>`-tags and on-event handlers were detected in versions prior to 0.4.0. As a result, downstream software that relies on `sanitize-svg` and expects resulting SVGs to be safe, may be vulnerable to cross-site scripting. This vulnerability was addressed in v0.4.0. There are no known workarounds\n\n","published":"2023-01-04T14:57:04.902Z","modified":"2026-07-15T01:49:02.911888857Z","cvss":{"score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"npm","name":"@mattkrick/sanitize-svg","fixedVersion":"0.4.0"}],"fix":{"url":"https://github.com/mattkrick/sanitize-svg/commit/b107e453ede7b58adcccae74a3e474c012eec85d","label":"mattkrick/sanitize-svg@b107e45"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/22xxx/CVE-2023-22461.json"},{"type":"ADVISORY","url":"https://github.com/mattkrick/sanitize-svg/security/advisories/GHSA-h857-2g56-468g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-22461"},{"type":"FIX","url":"https://github.com/mattkrick/sanitize-svg/commit/b107e453ede7b58adcccae74a3e474c012eec85d"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:02.911888857Z"}}
