{"identifier":"CVE-2026-96889","cve":{"id":"CVE-2026-96889","description":"A flaw was found in librsvg. When processing an SVG document containing nested XML inclusions (Xincludes) with duplicate entity declarations, a use-after-free error can occur. This vulnerability arises because the library incorrectly frees an XML entity that is still in use by the parser. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code.","published":"2026-09-23T20:17:27.587000+00:00","modified":"2026-10-29T20:17:37.103000+00:00","status":"Awaiting Analysis","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-416"],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:86331","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:86841","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:86842","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:86921","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92212","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92213","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92214","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92218","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92336","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92353","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92382","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:92579","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/security/cve/CVE-2026-96889","source":"secalert@redhat.com"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539279","source":"secalert@redhat.com"},{"url":"https://crates.io/crates/librsvg","source":"secalert@redhat.com"},{"url":"https://gitlab.gnome.org/GNOME/librsvg/-/work_items/1241","source":"secalert@redhat.com"},{"url":"https://rustsec.org/advisories/RUSTSEC-2026-0305.html","source":"secalert@redhat.com"},{"url":"https://gitlab.gnome.org/GNOME/librsvg/-/work_items/1241","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-25T17:53:42.623078Z","id":"CVE-2026-96889","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-29T23:58:42.548084+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00543,"percentile":0.45536,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"access.redhat.com","source_url":"https://access.redhat.com/errata/RHSA-2026:86331","investigate_url":"https://investigate.aeglixmind.com/#access.redhat.com"},{"domain":"bugzilla.redhat.com","source_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539279","investigate_url":"https://investigate.aeglixmind.com/#bugzilla.redhat.com"},{"domain":"crates.io","source_url":"https://crates.io/crates/librsvg","investigate_url":"https://investigate.aeglixmind.com/#crates.io"},{"domain":"gitlab.gnome.org","source_url":"https://gitlab.gnome.org/GNOME/librsvg/-/work_items/1241","investigate_url":"https://investigate.aeglixmind.com/#gitlab.gnome.org"},{"domain":"rustsec.org","source_url":"https://rustsec.org/advisories/RUSTSEC-2026-0305.html","investigate_url":"https://investigate.aeglixmind.com/#rustsec.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-96889","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-96889","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-96889","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
