CVE-2026-107743

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 permissioncallback that unconditionally returns true (no capability check, no nonce), together with the mapsterwriteconfigtoacf() helper only sanitizing string config values with sanitizetextfield() — which strips HTML tags but leaves quote characters intact — and the mapsterwpmap shortcode renderer in mapsterwordpressmapsshortcodedisplay() concatenating the stored loadingbackgroundcolor value into a single-quoted inline style attribute without escattr(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
