{"id":"CVE-2025-55166","summary":"svg-sanitizer By-Passing Attribute Sanitization","details":"savg-sanitizer is a PHP SVG/XML sanitizer. Prior to version 0.22.0, the sanitization logic in the cleanXlinkHrefs method only searches for lower-case attribute name, which allows to by-pass the isHrefSafeValue check. As a result this allows cross-site scripting or linking to external domains. This issue has been patched in version 0.22.0.","aliases":["GHSA-22wq-q86m-83fh"],"modified":"2026-08-12T03:51:38.098263342Z","published":"2025-08-12T16:25:17.220Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-601","CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/55xxx/CVE-2025-55166.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/55xxx/CVE-2025-55166.json"},{"type":"ADVISORY","url":"https://github.com/darylldoyle/svg-sanitizer/security/advisories/GHSA-22wq-q86m-83fh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55166"},{"type":"FIX","url":"https://github.com/darylldoyle/svg-sanitizer/commit/5a0a1eaf0c6b0b540dc945fe30c93cf106b357c1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/darylldoyle/svg-sanitizer","events":[{"introduced":"0"},{"fixed":"5a0a1eaf0c6b0b540dc945fe30c93cf106b357c1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.22.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["0.21.0","0.20.0","0.19.0","0.18.0","0.17.0","0.16.0","0.15.4","0.15.3","0.15.2","0.15.1","0.15.0","0.14.1","0.14.0","0.13.3","0.13.2","0.10.0","0.9.2","0.9.1","0.9.0","0.8.2","0.8.1","0.8.0","0.7.2","0.7.1","0.7.0","0.6.0","0.5.3.1","0.5.3","0.5.2","0.5.1","0.5.0","0.4.1","0.4.0","0.3.0","0.2.1","0.2.0","0.1.6","0.1.5","0.1.4","0.1.3","0.1.2","0.1.1","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-55166.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
