The Alex Furr Progress Tracker up to version 0.9.3 suffers from a DOM-based cross-site scripting vulnerability caused by improper neutralization of input during web page generation. This allows an attacker with low privileges and requiring user interaction to potentially execute malicious scripts in the context of the affected application. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, low privileges required, user interaction needed, 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 victim's browser within the context of the Progress Tracker application. This may lead to limited disclosure of information, modification of data, or disruption of service. The impact is assessed as medium severity based on the CVSS score of 6.5.

No patch or official remediation guidance is currently available for this vulnerability. Users should monitor the vendor's advisories for any forthcoming fixes or updates. Until a patch is released, cautious handling of untrusted input and minimizing exposure to untrusted sources may reduce risk.
