CVE-2026-10692: Inefficient Regular Expression Complexity in johnhuang316 code-index-mcp
A vulnerability in johnhuang316 code-index-mcp up to version 2.14.0 allows remote attackers to cause inefficient regular expression complexity via the is_safe_regex_pattern function in the search_code_advanced component. This can lead to performance degradation or denial of service. The issue is fixed in version 2.14.1.
AI Analysis
Technical Summary
CVE-2026-10692 describes a weakness in the is_safe_regex_pattern function of the search_code_advanced component in johnhuang316 code-index-mcp versions up to 2.14.0. Manipulating the regex argument can trigger inefficient regular expression complexity, potentially impacting system performance. The vulnerability is remotely exploitable and a public exploit is available. The issue is resolved by upgrading to version 2.14.1, which includes a patch identified as 25bc02fac74051ddae15ce79e952f00211b1ea6b.
Potential Impact
The vulnerability allows remote attackers to cause inefficient regular expression complexity, which can degrade application performance or lead to denial of service conditions. There is no indication of privilege escalation, data confidentiality, or integrity impact. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, and low impact on availability.
Mitigation Recommendations
Upgrade johnhuang316 code-index-mcp to version 2.14.1 or later, which contains the official patch for this vulnerability (commit 25bc02fac74051ddae15ce79e952f00211b1ea6b). No other mitigations are specified or required.
