CVE-2025-12369 is a stored cross-site scripting vulnerability (CWE-79) in the Extensions for Leaflet Map WordPress plugin. It affects all versions up to and including 4.7. The issue is due to improper neutralization of input in the geojsonmarker shortcode, where user-supplied attributes are not properly sanitized or escaped before output. Authenticated attackers with Contributor-level permissions or higher can exploit this to inject arbitrary JavaScript code that executes in the context of users viewing the compromised pages. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, and partial confidentiality and integrity impact without availability impact. No known exploits in the wild have been reported, and no patch or remediation details are provided.

Successful exploitation allows authenticated users with Contributor-level access or above to inject persistent malicious scripts into pages via the geojsonmarker shortcode. These scripts execute in the browsers of users who visit the affected pages, potentially leading to partial confidentiality and integrity compromise of user data or session information. There is no impact on availability. The vulnerability could facilitate actions such as session hijacking or unauthorized actions performed in the context of affected users.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit Contributor-level access to trusted users only and consider disabling or removing the Extensions for Leaflet Map plugin if feasible. Monitor official vendor channels for updates regarding patches or mitigations.
