CVE-2026-28363

Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand zu verursachen oder andere nicht näher spezifizierte Angriffe durchzuführen.

### 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.

In OpenClaw before 2026.2.23, tools.exec.safeBins validation for sort could be bypassed via GNU long-option abbreviations (such as --compress-prog) in allowlist mode, leading to approval-free execution paths that were intended to require approval. Only an exact string such as --compress-program was denied.

OpenClaw version 2026.2.22-2 prior to 2026.2.23 tools.exec.safeBins validation for sort command fails to properly validate GNU long-option abbreviations, allowing attackers to bypass denied-flag checks via abbreviated options. Remote attackers can execute sort commands with abbreviated long options to skip approval requirements in allowlist mode.
