OpenClaw < 2026.3.31 - Path Traversal via Inbound Channel Attachment Path in ACP Dispatch
Noroxi assessment
Priority: Monitor (action score 28/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.62% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: OpenClaw OpenClaw 2026.3.31.
Low priority for now. Upgrade to OpenClaw OpenClaw 2026.3.31 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
OpenClaw before 2026.3.31 contains a path traversal vulnerability in ACP dispatch that allows attackers to read arbitrary files by manipulating inbound channel attachment paths. Remote attackers can bypass attachment-cache and root directory checks to access files outside intended directories.
