OpenClaw < 2026.2.21 - Prototype Pollution via Debug Override Path

OpenClaw versions prior to 2026.2.21 accept prototype-reserved keys in runtime /debug set override object values, allowing prototype pollution attacks. Authorized /debug set callers can inject __proto__, constructor, or prototype keys to manipulate object prototypes and bypass command gate restrictions.

OpenClaw < 2026.3.22 - Missing controlScope Enforcement in Send Action

OpenClaw before 2026.3.22 fails to enforce controlScope restrictions on the send action, allowing leaf subagents to message controlled child sessions beyond their authorized scope. Attackers can exploit this by using the send action to communicate with child sessions without proper scope validation, bypassing intended access control restrictions.

OpenClaw - Shell-Bleed Protection Preflight Validation Bypass

OpenClaw versions prior to commit 8aceaf5 contain a preflight validation bypass vulnerability in shell-bleed protection that allows attackers to execute blocked script content by using piped or complex command forms that the parser fails to recognize. Attackers can craft commands such as piped execution, command substitution, or subshell invocation to bypass the validateScriptFileForShellBleed() validation checks and execute arbitrary script content that would otherwise be blocked.

OpenClaw versions prior to 2026.2.25 fail to enforce dmPolicy and allowFrom authorization checks on Discord direct-message reaction notifications, allowing non-allowlisted users to enqueue reaction-derived system events. Attackers can exploit this inconsistency by reacting to bot-authored DM messages to bypass DM authorization restrictions and trigger downstream automation or tool policies.

OpenClaw Discord moderation authorization used untrusted sender identity in tool-driven flows

OpenClaw is a personal AI assistant. In versions 2026.2.17 and below, the Discord moderation action handling (timeout, kick, ban) uses sender identity from request parameters in tool-driven flows, instead of trusted runtime sender context. In setups where Discord moderation actions are enabled and the bot has the necessary guild permissions, a non-admin user can request moderation actions by spoofing sender identity fields. This issue has been fixed in version 2026.2.18.
