Medium (6.0) in openclaw openclaw. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in openclaw 2026.2.21.
OpenClaw versions prior to 2026.2.21 contain a stdin-only policy bypass vulnerability in the grep tool within tools.exec.safeBins that allows attackers to read arbitrary files by supplying a pattern via the -e flag parameter. Attackers can include a positional filename operand to bypass file access restrictions and read sensitive files.env from the working directory.
