Technical Analysis

CVE-2026-90492 is an OS command injection vulnerability in webgjc web_robot versions 2.4.0, 2.5.0, and 2.8.0. The vulnerability arises from improper handling of the argument case_name in the controller_listen/controller_recover functions of the py/web.py file. An attacker can remotely manipulate this argument to execute arbitrary OS commands. The vulnerability has been publicly disclosed, and no vendor response or patch is currently available.

Potential Impact

Successful exploitation allows remote attackers to execute arbitrary OS commands on the affected system, potentially leading to partial confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:L/I:L/A:L). This could compromise system stability and data security.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no patch links are available, users should consider applying workarounds such as restricting access to the vulnerable functions or input validation on the case_name argument until an official fix is released.
