CVE-2026-71189 is a cross-site scripting (XSS) vulnerability in Toptech Systems TMS7 version 7.6.3. An attacker can craft a request that, when executed by another user, causes attacker-supplied JavaScript to run in the victim's browser within their session context. The vulnerability has a low CVSS score of 3.5, indicating limited impact. There is no information on available patches or vendor advisories. No known exploits are reported in the wild.
AI Analysis
Technical Summary
This vulnerability allows an attacker to construct a request that, if executed by another application user, results in the execution of attacker-supplied JavaScript code within that user's browser session. The flaw is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The CVSS 3.1 base score is 3.5, reflecting network attack vector, low attack complexity, required privileges, and user interaction, with limited confidentiality impact and no integrity or availability impact.
Potential Impact
Successful exploitation leads to execution of attacker-controlled JavaScript in the victim's browser session, potentially enabling actions such as session hijacking or UI manipulation. However, the CVSS score and vector indicate limited confidentiality impact and no integrity or availability impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed—check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution with untrusted inputs and avoid executing suspicious requests. No vendor advisory states that no action is required or that the issue is already mitigated.
