{"schemaVersion":3,"id":"CVE-2026-17576","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The InfiniteWP Client plugin for WordPress is vulnerable to SQL Injection via the get_comments action in versions up to, and including, 1.13.9. This is due to insufficient escaping on the array-key names supplied in the JSON request body before use in a SQL statement: IWP_MMB_Comment::get_comments() calls extract() on $args (which silently skips keys that are not valid PHP variable names) but a second foreach($args as $checkbox => $checkbox_val) processes every key, strips the 'iwp_get_comments_' prefix with str_replace(), wraps the remainder in single quotes, and imploded it into an IN(...) clause that is executed via $wpdb->get_results() with no prepare(). Because the request body is read from php://input and JSON-decoded, wp_magic_quotes() never touches the data, so quote characters in keys pass through unaltered. This makes it possible for authenticated attackers, with administrator-level access and above (an administrator can register their own public key via add_site using the plugin's WP-admin-generated activation_key and then issue signed get_comments requests), to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.","dates":{"published":"2026-09-18T06:38:51.870Z","modified":"2026-09-18T14:31:43.041Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00275,"percentile":0.18672,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00275},"history":[{"date":"2026-09-18T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00275,"percentile":0.18672}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00275,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.
