CVE-2026-0521

Estado: AnalizadaMedia (5.6)—

A reflected cross-site scripting (XSS) vulnerability in the PDF export functionality of the TYDAC AG MAP+ solution allows unauthenticated attackers to craft a malicious URL, that if visited by a victim, will execute arbitrary JavaScript in the victim's context. Such a URL could be delivered through various means, for instance, by sending a link or by tricking victims to visit a page crafted by the attacker.

This issue was verified in MAP+: 3.4.0.

CVSS
