EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.1 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 99% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

OpenClaw versions prior to 2026.2.26 contain an approval bypass vulnerability in system.run execution that allows attackers to execute commands from unintended filesystem locations by rebinding writable parent symlinks in the current working directory after approval. An attacker can modify mutable parent symlink path components between approval and execution time to redirect command execution to a different location while preserving the visible working directory string.
