{"schema":"threatline.record/2","record":{"id":"CVE-2026-109972","aliases":[],"summary":"s2Member <= 261011 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'date_format' Shortcode Attribute","details":"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.","categories":["Unclassified"],"product":"s2Member – Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions","vendor":"clavaque","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109972","source_modified_at":"2026-10-28T06:45:08.551Z","fetched_at":"2026-10-28T08:18:35.509402Z","product":"s2Member – Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions","vendor":"clavaque","versions":[{"version":"0","status":"affected","lessThanOrEqual":"261011","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T06:45:08.551Z","modified_at":"2026-10-28T06:45:08.551Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109972","fetched_at":"2026-10-28T08:18:35.509402Z","source_modified_at":"2026-10-28T06:45:08.551Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2782f0f7-625d-4141-8e2c-4bdaa0219007?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/classes/sc-gets-in.inc.php#L119"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/classes/sc-gets-in.inc.php#L98"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/classes/sc-gets-in.inc.php#L53"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/s2member/trunk/src/includes/codes.inc.php#L24"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3751344/s2member/trunk/src/includes/classes/sc-gets-in.inc.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T06:45:08.551Z","content_hash":"8e6ae632fe147347a0785646268b8815d7182038bbac9c972e8fb5ff854b60dc"}}
