The vulnerability CVE-2025-26539 affects the petkivim Embed Google Map plugin (versions up to 3.2) and is classified as a stored cross-site scripting (XSS) issue. It results from improper input sanitization during web page generation, enabling attackers to inject and store malicious scripts that execute in the context of users viewing the affected pages. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with a scope change and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of affected users, potentially leading to data disclosure, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. However, no known exploits have been reported in the wild, and the impact remains theoretical based on the vulnerability description.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates. Until a fix is available, consider restricting plugin usage or applying input validation controls where possible to mitigate risk.
