{"id":"CVE-2026-45012","aliases":["GHSA-pr28-mf3q-qpg6"],"url":"https://o3.security/vulnerability/CVE-2026-45012","summary":"Apostrophe has authenticated SSRF in rich-text widget import via @apostrophecms/area/validate-widget","details":"ApostropheCMS is an open-source Node.js content management system. Versions up to and including 4.29.0 contain an authenticated server-side request forgery (SSRF) in the rich-text widget import flow. An authenticated user who can submit/edit rich-text widget content can cause the server to fetch attacker-controlled URLs during widget validation. For image-compatible responses, the fetched content can be persisted and re-hosted by Apostrophe, allowing response exfiltration. As of time of publication, no known patched versions are available.","published":"2026-06-12T20:44:48.842Z","modified":"2026-08-12T03:51:47.189310390Z","cvss":{"score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L"},"epss":{"score":0.00197,"percentile":0.09787,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"apostrophe","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45012.json"},{"type":"ADVISORY","url":"https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-pr28-mf3q-qpg6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45012"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:47.189310390Z"}}
