{"cve":"CVE-2026-109972","nvd":{"published":"2026-10-28T07:16:45.017","modified":"2026-10-28T07:16:45.017","status":"Received","description":"The s2Member – Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'date_format' parameter in all versions up to, and including, <= 261011 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload bypasses wp_kses_post() on save because it contains no literal angle brackets — only backslash-escaped sequences that PHP's date() materializes into HTML tag characters at render time after WordPress's shortcode_parse_atts() applies stripcslashes() to the attribute value.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/classes/sc-gets-in.inc.php#L119","https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/classes/sc-gets-in.inc.php#L53","https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/classes/sc-gets-in.inc.php#L98","https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/codes.inc.php#L24","https://plugins.trac.wordpress.org/changeset/3751344/s2member/trunk/src/includes/classes/sc-gets-in.inc.php"],"products":[],"source":"nvd","synced_at":"2026-10-28T07:37:43.411221249+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
