{"id":"CVE-2026-46697","summary":"Fediverse Embeds: Unauthenticated SSRF / open proxy via REST media-proxy endpoint","details":"Fediverse Embeds embeds fediverse posts on WordPress sites. Prior to version 1.5.8, Fediverse Embeds registered an unauthenticated REST route ftf/media-proxy (includes/Media_Proxy.php) with permission_callback =\u003e __return_true that accepted a base64-encoded URL and forwarded it to wp_remote_get($url) without enforcing any allowlist. The plugin's source contained a comment block explicitly acknowledging that the request should be validated against allowed fediverse domains, but in 1.5.7 the validation only set a local $can_download_media flag that was never read. The full response body was echoed back to the caller, so this was a full-read SSRF / open proxy reachable by any anonymous visitor. This issue has been patched in version 1.5.8.","aliases":["GHSA-mpq6-hjh3-m543"],"modified":"2026-07-08T08:13:52.668961750Z","published":"2026-06-11T17:16:03.883Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46697.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"1.5.8"}]}],"cwe_ids":["CWE-918"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46697.json"},{"type":"ADVISORY","url":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/security/advisories/GHSA-mpq6-hjh3-m543"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46697"},{"type":"FIX","url":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/commit/2f021faf4dadaccef67eda7b81a0b7ceaef450df"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin","events":[{"introduced":"0"},{"fixed":"2f021faf4dadaccef67eda7b81a0b7ceaef450df"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46697.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
