{"schema":"threatline.record/2","record":{"id":"CVE-2026-109401","aliases":[],"summary":"WP Mail Logging <= 1.17.0 - Authenticated (Administrator+) Sensitive Information Exposure in LIKE Wildcard in Personal Data Export Email","details":"The WP Mail Logging plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.17.0 via the 'email_address' parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to extract complete logged mail rows belonging to other users — including recipient addresses, message subjects, full message bodies, and any URLs contained therein — whose addresses happen to match the wildcard. Exploitation requires an administrator to process a personal-data export request for the attacker's email address via the standard WordPress privacy workflow, and the attacker's address must contain a LIKE wildcard character (such as an underscore) that matches at least one other user's address in the mail log.","categories":["Unclassified"],"product":"WP Mail Logging","vendor":"smub","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109401","source_modified_at":"2026-10-16T14:21:19.789Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"WP Mail Logging","vendor":"smub","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.17.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":2.7,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00324,"percentile":0.2421,"score_date":"2026-10-23"},"published_at":"2026-10-16T06:41:07.717Z","modified_at":"2026-10-16T14:21:19.789Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109401","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T14:21:19.789Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109401","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/f2b96f36-090d-4ed3-aa2c-dafa89d255cc?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-mail-logging/tags/1.17.0/lib/vendor/brandonwamboldt/wp-orm/src/Query.php#L399"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-mail-logging/tags/1.17.0/src/WPML_PrivacyController.php#L76"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-mail-logging/tags/1.17.0/src/WPML_PrivacyController.php#L82"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3746095/wp-mail-logging/trunk/src/WPML_PrivacyController.php?old=3464813&old_path=wp-mail-logging%2Ftrunk%2Fsrc%2FWPML_PrivacyController.php"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3746095%40wp-mail-logging%2Ftags%2F1.17.1&old=3705796%40wp-mail-logging%2Ftags%2F1.17.0"}],"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":"2026-10-16T14:21:00.958912Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T14:21:19.789Z","content_hash":"b310020c30ef808074a6bfc2fafd41f27f1b40f61f1e360bed489a52d9fa19a0"}}
