CVE-2026-100600
MediumCVSS 5.3Summary
ClawHub (the openclaw/clawhub application/backend) does not bind anonymous HTTP API requests to a trusted caller identity, so all direct anonymous API requests share a single default quota allowance. A remote, unauthenticated caller can drain that shared allowance and thereby deny or degrade API access for unrelated visitors. In addition, when the TRUST_FORWARDED_IPS option is enabled without an authenticated edge/proxy, clients can supply arbitrary forwarded IP headers to select quota identities of their choosing and evade rate limiting.
Risk Assessment
An attacker can cause a denial of service on the API, blocking access for other users, and bypass rate limiting by forging IP headers. This affects availability and the integrity of access controls.
Recommendation
Update ClawHub to revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650 or a later descendant (PR #3684). Self-hosted deployments should update to that revision or a later descendant.
Other vulnerabilities in ClawHub
See all- CVE-2026-100604Medium
ClawHub (openclaw/clawhub) contains an incorrect authorization vulnerability: an organization-owned skill retains the ownerUserId of its original publisher, and transfer and lifecycle authorization checks trust that historical user before requiring current organization privileges. An authenticated user who originally published an organization skill can therefore transfer, delete, or restore that skill even after their organization privileges have been revoked or downgraded.
- CVE-2026-100603Medium
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.
- CVE-2026-100602Medium
ClawHub (openclaw/clawhub application/backend) contains a missing authorization check in the changelog preview feature. A signed-in caller can invoke the public skills:generateChangelogPreview action for a skill they are not authorized to access; the previous version is read without the file-read authorization enforced on normal content access, and up to 8,000 characters of quarantined content may be submitted to the AI provider and reflected in the preview returned to the caller, disclosing restricted skill content.
- CVE-2026-100601Medium
ClawHub (openclaw/clawhub) application/backend contains a server-side request forgery vulnerability in the public profile preview's image fetching. The preview accepts a user-supplied image URL and checks the textual hostname against private-address patterns, but does not validate or pin the resolved network destination, so a public-looking hostname can resolve to an internal address or change resolution between validation and connection (DNS rebinding).
Original NVD description (English source)
ClawHub (the openclaw/clawhub application/backend) does not bind anonymous HTTP API requests to a trusted caller identity, so all direct anonymous API requests share a single default quota allowance. A remote, unauthenticated caller can drain that shared allowance and thereby deny or degrade API access for unrelated visitors. In addition, when the TRUST_FORWARDED_IPS option is enabled without an authenticated edge/proxy, clients can supply arbitrary forwarded IP headers to select quota identities of their choosing and evade rate limiting. The issue was confirmed at revision cbfee7343ddc867316dd9b3de6fa8856730f9f41; the complete historical affected range was not established. It is fixed in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650 (PR #3684), where direct anonymous calls are redirected to the public API origin without consuming quota and forged identity assertions return HTTP 401. The npm CLI and OpenClaw runtime are separate products and are not affected.
