CVE-2026-27360 describes a stored cross-site scripting vulnerability in the 10Web Photo Gallery plugin for WordPress, affecting versions up to 1.8.38. The issue is due to improper input neutralization during web page generation, which allows attackers with high privileges to inject malicious scripts that execute when other users view the affected pages. The vulnerability has a CVSS 3.1 base score of 5.9, reflecting medium severity with network attack vector, low attack complexity, required privileges, and user interaction. No patch or official remediation guidance is provided in the available data.

Successful exploitation of this vulnerability can lead to execution of malicious scripts in the context of the affected web application, potentially resulting in partial compromise of confidentiality, integrity, and availability. The attacker must have high privileges and rely on user interaction, which limits the ease of exploitation. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict high-privilege user access to the plugin and avoid actions that could trigger stored XSS payloads. Monitor vendor communications for updates on patches or mitigations.
