{"id":"CVE-2026-42860","aliases":["GHSA-64cv-vxpr-j6vc","PYSEC-2026-58"],"url":"https://o3.security/vulnerability/CVE-2026-42860","summary":"Open edx Enterprise Service: SSRF via SAML metadata URL in sync_provider_data endpoint","details":"The Open edx Enterprise Service app provides enterprise features to the Open edX platform. From 7.0.2 to 7.0.4, the sync_provider_data endpoint in SAMLProviderDataViewSet fetches SAML metadata from a URL stored in SAMLProviderConfig.metadata_source. An authenticated user with the Enterprise Admin role can set this field to an arbitrary URL via the SAMLProviderConfigViewSet PATCH endpoint, then trigger a server-side HTTP request by calling sync_provider_data. The fetch in fetch_metadata_xml() passes the URL directly to requests.get() with no scheme enforcement, IP filtering, or timeout. This vulnerability is fixed in 7.0.5.","published":"2026-05-11T17:40:09.858Z","modified":"2026-08-12T03:51:42.988040117Z","cvss":{"score":8.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N"},"epss":{"score":0.00301,"percentile":0.22152,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"edx-enterprise","fixedVersion":"7.0.5"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42860.json"},{"type":"ADVISORY","url":"https://github.com/openedx/edx-enterprise/security/advisories/GHSA-64cv-vxpr-j6vc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42860"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:42.988040117Z"}}
