CVE-2026-76054

API token disclosure via inherited subprocess environment

Published Aug 24, 2026 · Updated Aug 24, 2026

Information disclosure in Black Duck C/C++ Tool 1.0.17 through 3.0.6 allows local users to obtain its API token during scans. Build capture and signature scanning launch project-controlled subprocesses with the scanner's ambient environment, including BLACKDUCK_API_TOKEN or BD_HUB_TOKEN. The issue is reachable only when a token is supplied through either environment variable and untrusted build code executes; exposure grants that code the token's Black Duck permissions.
