CVE-2026-28363

HIGH

OpenClaw's tools.exec.safeBins sort long-option abbreviation bypass can skip exec approval in allowlist mode

Published March 3, 2026Updated March 13, 2026Source: osv

Summary

### Summary In OpenClaw, `tools.exec.safeBins` validation for `sort` could be bypassed via GNU long-option abbreviations in allowlist mode, allowing approval-free execution paths that should require approval. ### Affected Packages / Versions - Ecosystem: npm - Package: `openclaw` - Latest published version checked: `2026.2.22-2` - Affected range: `<= 2026.2.22-2` - Fixed version: `2026.2.23` ### Impact When all of the following are true: - `tools.exec.security=allowlist` - `tools.exec.ask=on-miss` - `tools.exec.safeBins` includes `sort` abbreviated GNU long options (for example `--compress-prog`) could bypass denied-flag checks and be treated as allowlist-satisfied safe-bin usage, skipping approval. ### Root Cause Long-option handling matched denied flags by exact string and accepted unknown long options with inline values instead of failing closed. ### Fix Commit(s) - `3b8e33037ae2e12af7beb56fcf0346f1f8cbde6f` ### Release Process Note `patched_versions` is pre-set to the released version (`2026.2.23`). This advisory now reflects released fix version `2026.2.23`. OpenClaw thanks @tdjackey for reporting.
