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.","published_at":"2026-06-11T17:15:52.767000Z","last_modified_at":null,"cvss_v3_score":5.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-918"],"nvd_references":["https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/security/advisories/GHSA-cr42-rgq6-whjh","https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/commit/93821405790ccc7a80528e91b34b624606b54969"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:38.837790Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"stefanbohacek","vendor_name":"stefanbohacek","product_slug":"fediverse-embeds-wordpress-plugin","product_name":"fediverse-embeds-wordpress-plugin","version_start":"< 1.5.9","version_start_inclusive":true,"version_end":"< 1.5.9","version_end_inclusive":true,"cpe23_uri":"cve5:stefanbohacek:fediverse-embeds-wordpress-plugin:< 1.5.9:< 1.5.9"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/security/advisories/GHSA-cr42-rgq6-whjh","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/stefanbohacek/fediverse-embeds-wordpress-plugin/commit/93821405790ccc7a80528e91b34b624606b54969","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-11T17:15:52.767000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:54:49.174395Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:49.174395Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:49.174395Z","label":"CVSS score revised","source":"cvelistv5"}]}
