CVE-2025-6383 is a stored cross-site scripting vulnerability in the WP-PhotoNav plugin for WordPress, affecting all versions up to and including 1.2.2. The issue stems from improper neutralization of input during web page generation, specifically insufficient sanitization and output escaping of user-supplied attributes in the photonav shortcode. Authenticated attackers with contributor or higher privileges can inject arbitrary web scripts that execute in the context of users visiting the compromised pages. The vulnerability has a CVSS 3.1 base score of 6.4, with network attack vector, low attack complexity, and privileges required at the contributor level. No known exploits in the wild have been reported, and no patch or official fix has been documented.

Successful exploitation allows an authenticated contributor or higher to inject and store malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to limited confidentiality and integrity impacts, such as session hijacking or content manipulation, but does not affect availability. The vulnerability requires authenticated access, limiting the attack surface.

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