CVE-2026-76055: OS command injection vulnerability
Improper Neutralization of Special Elements used in an OS Command in the package manager component of Black Duck blackduck-c-cpp before 3.0.7 allows an actor able to create a file within the scanned build directory to execute operating system commands as the account running the scan. Filesystem paths encountered while traversing the scanned directory are interpolated into command strings that are executed through a shell without quoting or escaping, so shell metacharacters within those paths are interpreted rather than treated as literal text. No control over the build command or the tool's configuration is required.
