CVE-2026-100603
ClawHub before 8c2de6c506 Skill Hiding via Coordinated Reports
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.
