OpenClaw before 2026.2.17 creates session transcript JSONL files with overly broad default permissions, allowing local users to read transcript contents. Attackers with local access can read transcript files to extract sensitive information including secrets from tool output.
Security readout for executives and security teams
Plain-English summary
OpenClaw versions before 2026.2.17 may leave session transcript files readable by local users. Those JSONL transcripts can contain sensitive tool output, including secrets. The main business risk is disclosure of credentials or operational data on systems where multiple users or processes can access the same host.
Executive priority
Treat this as high priority for developer and automation environments because transcript files may expose reusable secrets. Prioritize shared hosts and systems processing production credentials.
Technical view
This is a CWE-378 insufficient file permissions issue affecting OpenClaw before 2026.2.17. Session transcript JSONL files are created with overly broad default permissions, allowing local users to read transcript contents. The source CVSS is 8.4, local attack vector, low complexity, no user interaction.
Likely exposure
Exposure is most likely where OpenClaw before 2026.2.17 ran on shared workstations, servers, CI hosts, or developer systems and stored transcripts containing secrets or sensitive output.
Exploitation context
The bundle marks KEV as false and provides no evidence of active exploitation. Exploitation requires local access to a host containing affected transcript files.
Researcher notes
Sources do not provide exploit code or active exploitation evidence. The key validation question is whether affected transcript files exist and are readable by unintended local users. CVSS includes high confidentiality, integrity, and availability impact, but the described mechanism is transcript disclosure.
Mitigation direction
Upgrade OpenClaw to 2026.2.17 or later.
Review vendor advisory and patch notes for official remediation details.
Restrict access to existing transcript files until remediated.
Review exposed transcripts for secrets and rotate any affected credentials.
Reduce unnecessary local user access on systems running OpenClaw.
Validation and detection
Inventory OpenClaw installations and confirm versions before 2026.2.17.
Identify hosts where OpenClaw session transcripts were written.
Check transcript file permissions against vendor-fixed behavior.
Review whether transcript contents include credentials or sensitive tool output.
Confirm upgraded installations no longer create broadly readable transcripts.

Creation of Temporary File With Insecure Permissions
Creation of Temporary File With Insecure Permissions represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
