CVE-2026-101109 is a reflected XSS vulnerability in the ordasoft.com Vehicle Manager (Free) Joomla extension versions 1.0.0 through 6.5.7. The issue arises from improper neutralization of input during web page generation, specifically the 'title' parameter on the vehicle-detail page (task=view) being echoed directly into a double-quoted HTML attribute without encoding. An attacker can inject a double-quote to break out of the attribute context and insert arbitrary markup, including script tags, enabling cross-site scripting attacks.

Successful exploitation could allow an attacker to execute arbitrary JavaScript in the context of users visiting the vulnerable page, potentially leading to session hijacking, defacement, or other malicious actions. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low complexity, no privileges required, user interaction required, and low to limited impact on confidentiality, integrity, and availability.

No official patch or fix is currently documented. Users should check the vendor's advisory for updates. Until a fix is available, avoid using untrusted input in the 'title' parameter on the vehicle-detail page or implement manual input validation and output encoding as a temporary mitigation.
