CVE-2026-73614Public exploitNetwork attack vector

Command execution via truncated deny-pattern input

Published Aug 13, 2026 · Updated Aug 13, 2026

Command execution in Jovancoding Network-AI before 5.15.1 allows remote authenticated users to run arbitrary commands via crafted Bash tool input. ClaudeHookBridge's extractTarget() truncates the string evaluated against denyPatterns to 500 characters, although Claude Code executes the complete command. An attacker with influence over a Bash tool call can pad the command so prohibited content begins after byte 500, bypassing the sole hard block in default observe mode.
