{"schema":"threatline.record/2","record":{"id":"CVE-2026-107770","aliases":[],"summary":"Photo Engine (Media Organizer & Lightroom) <= 6.5.6 - Missing Authorization to Unauthenticated Arbitrary Attachment Deletion and Upload via /?wplr-sync-api 'delete' / 'sync' action","details":"The Photo Engine (Media Organizer & Lightroom) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.5.6 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to permanently delete arbitrary media attachments via wp_delete_attachment and upload new attachments to the site, actions that require the upload_files or edit_others_posts capabilities. A Subscriber-level user can obtain their own wplr_auth_token directly from the profile.php page source, because the admin screen guard in Meow_WPLR_Sync_Admin::__construct() is commented out, causing wp_localize_script to leak the token into every admin page view; this token can then be used from a cookie-less HTTP session to invoke destructive actions on the /?wplr-sync-api endpoint.","categories":["Unclassified"],"product":"Photo Engine (Media Organizer & Lightroom)","vendor":"tigroumeow","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107770","source_modified_at":"2026-10-16T14:23:26.406Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Photo Engine (Media Organizer & Lightroom)","vendor":"tigroumeow","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.5.6","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00459,"percentile":0.38847,"score_date":"2026-10-23"},"published_at":"2026-10-16T06:41:01.346Z","modified_at":"2026-10-16T14:23:26.406Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107770","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T14:23:26.406Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107770","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2f32c361-9bb3-417b-a5a9-02e48bfa33b4?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wplr-sync/tags/6.5.6/classes/api.php#L116"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wplr-sync/tags/6.5.6/classes/api.php#L32"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wplr-sync/tags/6.5.6/classes/core.php#L923"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wplr-sync/tags/6.5.6/classes/admin.php#L155"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wplr-sync/tags/6.5.6/classes/api.php#L309"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wplr-sync/tags/6.5.6/classes/api.php#L201"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wplr-sync/tags/6.5.6/classes/admin.php#L56"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3737477/wplr-sync"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3737477/wplr-sync/trunk/classes/api.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-16T14:23:12.057643Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T14:23:26.406Z","content_hash":"296f9b26f64534f4cefbe9dc66fcf3b280412217cac97af52def3f737f08be2c"}}
