CVE-2026-100602: Missing Authorization in openclaw clawhub
CVE-2026-100602 is a high-severity vulnerability in the openclaw clawhub backend where a missing authorization check in the changelog preview feature allows signed-in users to access restricted skill content. This flaw permits unauthorized users to invoke the skills:generateChangelogPreview action on skills they should not access, potentially exposing up to 8,000 characters of quarantined content. The vulnerability was fixed in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650, deployed on 2026-09-11. Self-hosted deployments should update to this revision or later. The npm CLI and OpenClaw runtime are not affected.
AI Analysis
Technical Summary
The openclaw clawhub application backend contained a missing authorization check in the changelog preview feature. Specifically, a signed-in user could call the public skills:generateChangelogPreview action for a skill they were not authorized to access. This bypassed the normal file-read authorization, allowing the user to read the previous version of the skill content, including up to 8,000 characters of quarantined content submitted to the AI provider and reflected in the preview. The issue was confirmed at revision cbfee7343ddc867316dd9b3de6fa8856730f9f41. The vulnerability was fixed by PR #3682 in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650, deployed to clawhub.ai on 2026-09-11. Self-hosted users must update to this revision or later. The npm CLI and OpenClaw runtime are unaffected.
Potential Impact
Unauthorized signed-in users can access restricted skill content through the changelog preview feature, potentially disclosing sensitive quarantined data up to 8,000 characters in length. This unauthorized disclosure could lead to exposure of confidential information contained within restricted skills. There is no indication of privilege escalation, denial of service, or code execution. No known exploits are reported in the wild.
Mitigation Recommendations
A fix is available and was deployed to the clawhub.ai cloud service on 2026-09-11 in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650. Self-hosted deployments should update to this revision or a later descendant to remediate the vulnerability. The npm CLI and OpenClaw runtime products are not affected and require no action.
