CVE-2026-76055

Command execution via unescaped scanned filesystem paths

Published Aug 24, 2026 · Updated Aug 24, 2026

OS command injection in the package manager component of Black Duck C/C++ Tool before 3.0.7 allows local users to execute commands. Filesystem paths found during directory traversal are interpolated into shell command strings without quoting or escaping, causing metacharacters to be interpreted as shell syntax. Exploitation requires the ability to create a crafted path in the scanned build directory and runs commands as the scan account.
