The vulnerability CVE-2025-26770 in Joe Waymark (versions <= 1.5.0) is a stored cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. This allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that can affect confidentiality, integrity, and availability to a limited extent. The CVSS vector indicates network attack vector, low attack complexity, low privileges required, user interaction needed, and scope changed.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to limited confidentiality, integrity, and availability impacts. The CVSS score of 6.5 reflects a medium severity, with partial impact on data confidentiality, integrity, and availability. No known active exploitation has been reported.

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 for updates from the vendor. In the meantime, applying input validation and output encoding best practices may help mitigate risk. Avoiding use of affected versions or restricting user input where possible can reduce exposure.
