{"cve":"CVE-2026-107743","nvd":{"published":"2026-10-29T10:17:02.580","modified":"2026-10-29T11:17:25.273","status":"Received","description":"The Mapster WP Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.0.5. This is due to the /wp-json/mapster-wp-maps/save-mapmaker REST route being registered with a permission_callback that unconditionally returns true (no capability check, no nonce), together with the mapster_write_config_to_acf() helper only sanitizing string config values with sanitize_text_field() — which strips HTML tags but leaves quote characters intact — and the mapster_wp_map shortcode renderer in mapster_wordpress_maps_shortcode_display() concatenating the stored loading_background_color value into a single-quoted inline style attribute without esc_attr(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/mapster-wp-maps/tags/2.0.5/admin/api/class-mapster-wordpress-maps-api.php#L487","https://plugins.trac.wordpress.org/browser/mapster-wp-maps/tags/2.0.5/admin/api/config-converter.php#L523","https://plugins.trac.wordpress.org/browser/mapster-wp-maps/tags/2.0.5/admin/api/field-map.php#L304","https://plugins.trac.wordpress.org/browser/mapster-wp-maps/tags/2.0.5/public/class-mapster-wordpress-maps-public.php#L262","https://plugins.trac.wordpress.org/browser/mapster-wp-maps/tags/2.0.6/public/class-mapster-wordpress-maps-public.php"],"products":[],"source":"nvd","synced_at":"2026-10-29T11:44:53.014972599+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).
