CVE-2026-48844 is a high-severity vulnerability in Roundcube Webmail versions 1.6.x before 1.6.16 and 1.7.x before 1.7.1. It involves insecure code evaluation logic in the LDAP autovalues option, which could lead to code injection.
AI Analysis
Technical Summary
This vulnerability affects Roundcube Webmail versions 1.6.0 and 1.7.0, where insecure code evaluation in the LDAP autovalues option allows potential code injection. The issue is classified under CWE-670 (Always-Incorrect Control Flow Implementation). The vendor removed support for code evaluation in subsequent versions 1.6.16 and 1.7.1, mitigating the risk. The CVSS 3.1 score is 7.5, indicating high severity with network attack vector, high impact on confidentiality, integrity, and availability, and requiring low privileges but high attack complexity.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary code via the LDAP autovalues option, potentially compromising confidentiality, integrity, and availability of the affected system. The vulnerability requires network access and low privileges but has high attack complexity.
Mitigation Recommendations
A fix is available by upgrading Roundcube Webmail to version 1.6.16 or 1.7.1 or later, where support for code evaluation in the LDAP autovalues option has been removed. Users should apply these updates to remediate the vulnerability. Patch status is not explicitly confirmed in the input but the description states that support for code evaluation was removed in these versions, indicating an official fix.
