Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The npm package openclaw, versions before 2026.2.23, has a validation bypass in its tools.exec.safeBins checks for the sort command. Using GNU long-option abbreviations, such as --compress-prog, in allowlist mode got around the denial that only matched the exact option name --compress-program, so commands that were meant to require approval could run without it. Upgrade openclaw to version 2026.2.23 or later, which contains the fix.
