CVE-2026-73614: Interpretation Conflict in Jovancoding Network-AI
Network-AI ClaudeHookBridge before 5.15.1 truncates the target string to 500 characters before evaluating denyPatterns, while Claude Code executes the full untruncated command. Attackers can position dangerous content past byte 500 in a Bash command field to bypass the operator's hard-deny list and execute arbitrary commands.
AI Analysis
Technical Summary
The vulnerability in Jovancoding Network-AI (CVE-2026-73614) involves an interpretation conflict between the ClaudeHookBridge and Claude Code components. ClaudeHookBridge truncates input strings to 500 characters before evaluating denyPatterns, while Claude Code executes the entire command without truncation. This mismatch allows attackers to embed dangerous commands beyond the 500-character truncation point, effectively bypassing operator-defined deny lists and leading to arbitrary command execution. The CVSS 4.0 base score is 8.7, reflecting network attack vector, low complexity, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with low privileges can remotely execute arbitrary Bash commands by placing malicious content beyond the 500-character truncation limit in command fields. This bypasses deny lists intended to block dangerous commands, potentially compromising system confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented. Until a patch is available, operators should be cautious with command inputs exceeding 500 characters and consider additional manual validation or filtering beyond the built-in denyPatterns.
