{"id":"CVE-2026-41675","aliases":["GHSA-x6wf-f3px-wcqx"],"url":"https://o3.security/vulnerability/CVE-2026-41675","summary":"xmldom: XML node injection through unvalidated processing instruction serialization","details":"xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module. In @xmldom/xmldom prior to versions 0.9.10 and 0.8.13 and xmldom version 0.6.0 and prior, the package allows attacker-controlled processing instruction data to be serialized into XML without validating or neutralizing the PI-closing sequence ?>. As a result, an attacker can terminate the processing instruction early and inject arbitrary XML nodes into the serialized output. This issue has been patched in versions @xmldom/xmldom versions 0.9.10 and 0.8.13.","published":"2026-05-07T03:49:34.056Z","modified":"2026-08-07T11:51:04.320888163Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@xmldom/xmldom","fixedVersion":"0.8.13"},{"ecosystem":"npm","name":"@xmldom/xmldom","fixedVersion":"0.9.10"},{"ecosystem":"npm","name":"xmldom","fixedVersion":null}],"fix":{"url":"https://github.com/xmldom/xmldom/commit/7207a4b0e0bcc228868075ed991665ef9f73b1c2","label":"xmldom/xmldom@7207a4b"},"references":[{"type":"WEB","url":"https://github.com/xmldom/xmldom/releases/tag/0.8.13"},{"type":"WEB","url":"https://github.com/xmldom/xmldom/releases/tag/0.9.10"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-41675.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26234"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-41675"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41675.json"},{"type":"ADVISORY","url":"https://github.com/xmldom/xmldom/security/advisories/GHSA-x6wf-f3px-wcqx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41675"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2467629"},{"type":"FIX","url":"https://github.com/xmldom/xmldom/commit/7207a4b0e0bcc228868075ed991665ef9f73b1c2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:51:04.320888163Z"}}
