CVE-2026-43892: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in AntSwordProject antSword
CVE-2026-43892 is a high-severity cross-site scripting (XSS) vulnerability in AntSword, a cross-platform website management toolkit. Versions prior to 2.1.16 have incomplete input sanitization in the noxss() function, which allows injection of malicious code via jquery.terminal format code, leading to a one-click remote code execution (RCE). This vulnerability is fixed in version 2.1.16. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
AntSword versions before 2.1.16 suffer from an improper neutralization of input during web page generation (CWE-79), specifically incomplete sanitization in the noxss() function. This flaw enables attackers to inject malicious code through jquery.terminal format code, resulting in a one-click remote code execution vulnerability. The issue is addressed by the AntSwordProject in version 2.1.16. The CVSS v3.1 base score is 8.8, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to remote code execution with high impact on confidentiality, integrity, and availability of the affected system. This can allow attackers to execute arbitrary commands remotely, potentially compromising the entire system managed by AntSword versions prior to 2.1.16.
Mitigation Recommendations
Upgrade AntSword to version 2.1.16 or later, where the vulnerability is fixed. Since the vendor advisory indicates the issue is resolved in this version, applying this official fix is the recommended remediation. Patch status is confirmed by the vendor's versioning information. No additional mitigations are specified.
