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.","state":"PUBLISHED","assigner":"Wordfence","published_at":"2026-09-18 07:16:49","updated_at":"2026-09-18 07:16:49"},"problem_types":["CWE-89","CWE-89 CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')"],"metrics":[{"version":"3.1","source":"security@wordfence.com","type":"Primary","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","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"}},{"version":"3.1","source":"CNA","type":"DECLARED","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","data":{"baseScore":6.5,"baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/addons/comments/comments.class.php#L80","name":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/addons/comments/comments.class.php#L80","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3655042%40iwp-client&new=3655042%40iwp-client","name":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3655042%40iwp-client&new=3655042%40iwp-client","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/init.php#L1651","name":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/init.php#L1651","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/addons/comments/comments.class.php#L57","name":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/addons/comments/comments.class.php#L57","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/05c50442-570b-45cf-816a-c7a5b712ba21?source=cve","name":"https://www.wordfence.com/threat-intel/vulnerabilities/id/05c50442-570b-45cf-816a-c7a5b712ba21?source=cve","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/init.php#L131","name":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/init.php#L131","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/addons/comments/comments.class.php#L71","name":"https://plugins.trac.wordpress.org/browser/iwp-client/tags/1.13.6/addons/comments/comments.class.php#L71","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-17576","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-17576","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"revmakx","product":"InfiniteWP Client","version":"affected 1.13.9 semver","platforms":[]}],"timeline":[{"source":"CNA","time":"2026-09-17T18:35:29.000Z","lang":"en","value":"Disclosed"}],"solutions":[],"workarounds":[],"exploits":[],"credits":[{"source":"CNA","value":"Wordfence PRISM","lang":"en"}],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"defaultStatus":"unaffected","product":"InfiniteWP Client","vendor":"revmakx","versions":[{"lessThanOrEqual":"1.13.9","status":"affected","version":"0","versionType":"semver"}]}],"credits":[{"lang":"en","type":"finder","value":"Wordfence PRISM"}],"descriptions":[{"lang":"en","value":"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.
