    Title
    Fediverse Embeds: Public-nonce SSRF via ftf_get_site_info AJAX action
    Summary
    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.

    Title
    Fediverse Embeds: Unauthenticated SSRF / open proxy via REST media-proxy endpoint
    Summary
    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 => __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.

    Title
    Fediverse Embeds: Public-nonce SSRF via ftf_get_site_info AJAX action
    Summary
    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.
