The OSM Map Widget for Elementor plugin suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the plugin fails to adequately sanitize and escape user-supplied data in the Map Block URL attribute, allowing authenticated contributors or higher to inject malicious scripts. These scripts execute in the context of any user viewing the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 1.3.0. No known exploits are reported in the wild, and no patch links or vendor advisories have been provided.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages using the vulnerable plugin. This can lead to execution of arbitrary JavaScript in the context of users viewing the infected pages, potentially compromising user sessions or performing unauthorized actions. The vulnerability does not affect availability and requires authenticated access, but it can impact confidentiality and integrity of user data on affected sites.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the OSM Map Widget for Elementor plugin if possible. Monitor for updates from the vendor or plugin maintainers regarding patches or official mitigations.
