{"id":"CVE-2026-46698","summary":"Fediverse Embeds: Public-nonce SSRF via ftf_get_site_info AJAX action","details":"Fediverse Embeds embeds fediverse posts on WordPress sites. Prior to version 1.5.9, Fediverse Embeds registered the unauthenticated AJAX action wp_ajax_nopriv_ftf_get_site_info (includes/Site_Info.php) that verified a nonce ftf-fediverse-embeds-nonce and then called file_get_html($site_url) on the attacker-supplied URL. The same nonce was enqueued onto every public page containing a fediverse embed (via includes/Enqueue_Assets.php lines 41-46 + includes/Helpers.php lines 64-83), so the nonce gate was not an authentication boundary; any visitor of a public post with an embed could grab it and reuse it. This issue has been patched in version 1.5.9.","aliases":["GHSA-cr42-rgq6-whjh"],"modified":"2026-07-08T08:13:52.668638035Z","published":"2026-06-11T17:15:52.767Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46698.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"1.5.9"}]}],"cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46698.json"},{"type":"ADVISORY","url":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/security/advisories/GHSA-cr42-rgq6-whjh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46698"},{"type":"FIX","url":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/commit/93821405790ccc7a80528e91b34b624606b54969"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin","events":[{"introduced":"0"},{"fixed":"93821405790ccc7a80528e91b34b624606b54969"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46698.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:L/I:N/A:N"}]}
