Path Traversal Arbitrary File Read in OpenClaw browser upload action
CVE-2026-26329 affects OpenClaw prior to version 2026.2.14. The vulnerability is in the Gateway-exposed browser tool upload action, where attacker-supplied file paths were passed to Playwright's setInputFiles() API without being restricted to a safe upload root. Because absolute paths and path traversal sequences were accepted, an authenticated attacker could cause the Gateway host to access arbitrary local files outside the intended uploads directory. The issue is effectively a path traversal / improper pathname restriction flaw in the browser control hook path handling. The vendor states that version 2026.2.14 fixes this by confining upload paths to OpenClaw's temp uploads root (DEFAULT_UPLOAD_DIR) and rejecting traversal or escape paths.

Impact, mitigation & remediation
What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.
Impact
What an attacker gets, and what they’ve been doing with it.
FileReader, or via agent/browser snapshots and related browser automation flows. If the Gateway is exposed beyond loopback through LAN binding, tailnet exposure, reverse proxies, or tunnels, the practical attack surface and risk increase accordingly.Mitigation
If you can’t patch tonight, do this now.
browser tool through tool policy where it is not operationally required. Limit issuance and retention of valid Gateway credentials, including bearer tokens and passwords. Monitor for suspicious requests to POST /tools/invoke using tool=browser and action=upload, and to POST /hooks/file-chooser containing unexpected absolute paths or traversal sequences.Remediation
Patch, then assume compromise.
openclaw package to version 2026.2.14 or later. The fix confines upload paths to DEFAULT_UPLOAD_DIR and rejects traversal and escape paths before invoking Playwright setInputFiles(). The referenced fix commit is 3aa94afcfd12104c683c9cad81faf434d0dadf87.Exploits
