{"id":"CVE-2026-12975","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-12975","summary":"Apicurio Registry utilities allow SSRF and denial of service through XML parsing","details":"A flaw was found in Apicurio Registry. The ContentTypeUtil.isParsableXml() method creates a SAXParserFactory without enabling secure processing features or disabling external entity resolution. An attacker with artifact-write permission (or unauthenticated when the registry runs with default configuration) can upload a crafted XML document to trigger blind server-side request forgery (SSRF) via external DTD/entity fetch, or cause denial of service via entity expansion.","published":"2026-06-26T00:32:05Z","modified":"2026-11-04T18:00:05.261433596Z","cvss":{"score":8.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"io.apicurio:apicurio-registry-schema-util-common","fixedVersion":"3.3.1"},{"ecosystem":"Maven","name":"io.apicurio:apicurio-registry-schema-util-common","fixedVersion":"3.2.6"}],"fix":{"url":"https://github.com/Apicurio/apicurio-registry/pull/8197","label":"Apicurio/apicurio-registry#8197"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12975"},{"type":"WEB","url":"https://github.com/Apicurio/apicurio-registry/issues/8187"},{"type":"WEB","url":"https://github.com/Apicurio/apicurio-registry/pull/8197"},{"type":"WEB","url":"https://github.com/Apicurio/apicurio-registry/commit/48369d0e9008f7aab16dce5970c1ecbdd55e9aa5"},{"type":"WEB","url":"https://github.com/Apicurio/apicurio-registry/commit/a744fcb65991bbf04d4882f888655112afc5b06a"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:59360"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-12975"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2491688"},{"type":"WEB","url":"https://github.com/Apicurio/apicurio-registry/releases/tag/3.2.6"},{"type":"WEB","url":"https://github.com/Apicurio/apicurio-registry/releases/tag/3.3.1"},{"type":"PACKAGE","url":"https://github.com/apicurio/apicurio-registry"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-12975.json"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-11-04T18:00:05.261433596Z"}}
