Path Traversal in ClawHub Application

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
ClawHub (openclaw/clawhub) application/backend contains a flaw in the skill report moderation flow: four distinct ordinary authenticated accounts can report a visible skill and trigger automatic hiding (moderationStatus: hidden) of that skill from the catalog without any moderator decision. Because the reporter quota counts only reports filed against visible targets, the same accounts can repeat the process against additional skills; official skills are not exempt. The issue was confirmed at revision cbfee7343ddc867316dd9b3de6fa8856730f9f41; the complete historical affected range was not established. The fix (PR #3681) is included in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650; self-hosted deployments should update to that revision or a later descendant. The npm CLI and OpenClaw runtime are separate products and are not affected.

Executive Summary

CVE-2026-100603 is a flaw in the ClawHub application where four ordinary authenticated accounts can coordinate to report and automatically hide any visible skill from the catalog without moderator approval. The vulnerability stems from improper control of interaction frequency, allowing repeated exploitation since the reporter quota only counts reports against visible targets.

Detection Guidance

To detect this vulnerability, monitor for unusual patterns where four distinct authenticated accounts report and hide the same skill in ClawHub. Check logs for repeated skill moderation actions with identical reporter accounts. Look for skills being hidden without moderator intervention.

Impact Analysis

This vulnerability enables a coordinated denial-of-service by temporarily removing skills from the catalog without permanent damage or data exposure. Attackers can repeatedly hide skills, disrupting the availability of content for legitimate users.

Mitigation Strategies

Update ClawHub to revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650 or later. Ensure all instances are patched to prevent coordinated report exploitation. Verify authentication mechanisms for API requests and rate limiting to block anonymous IP-based identities.
