Summary

OpenClaw's unsanitized session ID enables path traversal in transcript file operations

Details

Description

OpenClaw versions <= 2026.2.9 construct transcript file paths using an unsanitized sessionId and also accept sessionFile paths without enforcing that they stay within the agent sessions directory.

A crafted sessionId and/or sessionFile (example: ../../etc/passwd) can cause path traversal when the gateway performs transcript file read/write operations.

Preconditions: an attacker must be able to authenticate to the gateway (gateway token/password). By default the gateway binds to loopback (local-only); configurations that expose the gateway widen the attack surface.

Affected Packages / Versions

Package: openclaw (npm)
Affected: <= 2026.2.9
Fixed: >= 2026.2.12

Fix

Fixed by validating session IDs (rejecting path separators / traversal sequences) and enforcing sessions-directory containment for session transcript file operations.

Fix Commit(s)

Additional Hardening

Mitigation

Upgrade to openclaw >= 2026.2.12.

CVE-2026-28482 (GCVE-0-2026-28482)

Vulnerability from cvelistv5 – Published: 2026-03-05 21:59 – Updated: 2026-03-09 20:40

Title

OpenClaw < 2026.2.12 - Path Traversal via Unsanitized sessionId and sessionFile Parameters

Summary

OpenClaw versions prior to 2026.2.12 construct transcript file paths using unsanitized sessionId parameters and sessionFile paths without enforcing directory containment. Authenticated attackers can exploit path traversal sequences like ../../etc/passwd in sessionId or sessionFile parameters to read or write arbitrary files outside the agent sessions directory.
