OpenClaw: Authenticated `/hooks/wake` and mapped `wake` payloads are promoted into the trusted `System:` prompt channel
## Impact
Authenticated `/hooks/wake` and mapped `wake` payloads are promoted into the trusted `System:` prompt channel.
An authenticated wake hook or mapped wake payload could be promoted into the trusted System prompt channel instead of an untrusted event.

OpenClaw: Lower-trust background runtime output is injected into trusted `System:` events, and local async exec completion misses the intended `exec-event` downgrade
## Impact
Lower-trust background runtime output is injected into trusted `System:` events, and local async exec completion misses the intended `exec-event` downgrade.
Lower-trust runtime/background output could be promoted into trusted System events, allowing prompt-injection into later agent turns.

OpenClaw < 2026.3.31 - Unsafe Request Body Replay via fetchWithSsrFGuard Cross-Origin Redirects
OpenClaw before 2026.3.31 (patched in 2026.4.8) contains a request body replay vulnerability in fetchWithSsrFGuard that allows unsafe request bodies to be resent across cross-origin redirects. Attackers can exploit this by triggering redirects to exfiltrate sensitive request data or headers to unintended origins.
OpenClaw: QQ Bot structured payloads could read arbitrary local files
## Summary
Before OpenClaw 2026.4.2, QQ Bot structured media payloads could read local files from attacker-chosen paths. A crafted structured payload could escape QQ Bot-owned media roots and cause arbitrary file reads on the host.
## Impact
Prompt-influenced structured payload output could exfiltrate any host file readable by the OpenClaw process through the QQ Bot media-send path. This was a real confidentiality bug on the host filesystem boundary.
## Affected Packages / Versions
- Package: `openclaw` (npm)
- Affected versions: `<= 2026.4.1`
- Patched versions: `>= 2026.4.2`
- Latest published npm version: `2026.4.1`
## Fix Commit(s)
OpenClaw < 2026.4.2 - PKCE Verifier Exposure via OAuth State Parameter
OpenClaw before 2026.4.2 reuses the PKCE verifier as the OAuth state parameter in the Gemini OAuth flow, exposing it through the redirect URL. Attackers who capture the redirect URL can obtain both the authorization code and PKCE verifier, defeating PKCE protection and enabling token redemption.
OpenClaw - Approval Bypass via Environment Variable Normalization
OpenClaw versions prior to commit b57b680 contain an approval bypass vulnerability due to inconsistent environment variable normalization between approval and execution paths, allowing attackers to inject attacker-controlled environment variables into execution without approval system validation. Attackers can exploit differing normalization logic to discard non-portable keys during approval processing while accepting them at execution time, bypassing operator review and potentially influencing runtime behavior including execution of attacker-controlled binaries.
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 < 2026.3.28 - Server-Side Request Forgery via Unguarded Image Download in fal Provider
OpenClaw before 2026.3.28 contains a server-side request forgery vulnerability in the fal provider image-generation-provider.ts component that allows attackers to fetch internal URLs. A malicious or compromised fal relay can exploit unguarded image download fetches to expose internal service metadata and responses through the image pipeline.
OpenClaw < 2026.3.28 - Incomplete WebSocket Session Termination on Device Removal and Token Revocation
OpenClaw before 2026.3.28 fails to disconnect active WebSocket sessions when devices are removed or tokens are revoked. Attackers with revoked credentials can maintain unauthorized access through existing live sessions until forced reconnection.
OpenClaw < 2026.3.24 - Arbitrary File Read via mediaUrl and fileUrl Parameters
OpenClaw before 2026.3.24 contains a sandbox bypass vulnerability in the message tool that allows attackers to read arbitrary local files by using mediaUrl and fileUrl alias parameters that bypass localRoots validation. Remote attackers can exploit this by routing file requests through unvalidated alias parameters to access files outside the intended sandbox directory.
OpenClaw < 2026.3.28 - Brute Force Attack via Missing Rate Limiting on Webhook Shared Secret Authentication
OpenClaw before 2026.3.28 contains a missing rate limiting vulnerability in the Nextcloud Talk webhook authentication that allows attackers to brute-force weak shared secrets. Attackers who can reach the webhook endpoint can exploit this to forge inbound webhook events by repeatedly attempting authentication without throttling.
OpenClaw < 2026.3.28 - Privilege Escalation via Missing Caller Scope Validation in Device Pair Approval
OpenClaw before 2026.3.28 contains a privilege escalation vulnerability in the /pair approve command path that fails to forward caller scopes into the core approval check. A caller with pairing privileges but without admin privileges can approve pending device requests asking for broader scopes including admin access by exploiting the missing scope validation in extensions/device-pair/index.ts and src/infra/device-pairing.ts.
OpenClaw < 2026.3.28 - Sender Policy Allowlist Bypass via Policy Downgrade in Google Chat and Zalouser Extensions
OpenClaw before 2026.3.28 contains a sender policy bypass vulnerability in the Google Chat and Zalouser extensions where route-level group allowlist policies silently downgrade to open policy. Attackers can exploit this policy resolution flaw to bypass sender restrictions and interact with bots despite configured allowlist restrictions.
OpenClaw < 2026.3.28 - Insufficient Scope Validation in node.pair.approve
OpenClaw before 2026.3.28 contains an insufficient scope validation vulnerability in the node pairing approval path that allows low-privilege operators to approve nodes with broader scopes. Attackers can exploit missing callerScopes validation in node-pairing.ts to extend privileges onto paired nodes beyond their authorization level.
OpenClaw < 2026.3.28 - Unauthorized Media Download via Zalo Channel
OpenClaw before 2026.3.28 downloads and stores inbound media from Zalo channels before validating sender authorization. Unauthorized senders can force network fetches and disk writes to the media store by sending messages that are subsequently rejected.
OpenClaw < 2026.3.8 - Sender Allowlist Bypass in Microsoft Teams Plugin via Route Allowlist Configuration
OpenClaw before 2026.3.8 contains a sender allowlist bypass vulnerability in its Microsoft Teams plugin that allows unauthorized senders to bypass intended authorization checks. When a team/channel route allowlist is configured with an empty groupAllowFrom parameter, the message handler synthesizes wildcard sender authorization, permitting any sender in the matched team/channel to trigger replies in allowlisted Teams routes.
OpenClaw before 2026.3.12 applies rate limiting only after successful webhook authentication, allowing attackers to bypass rate limits and brute-force webhook secrets. Attackers can submit repeated authentication requests with invalid secrets without triggering rate limit responses, enabling systematic secret guessing and subsequent forged webhook submission.
OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in fs-bridge staged writes where temporary file creation and population are not pinned to a verified parent directory. Attackers can exploit a race condition in parent-path alias changes to write attacker-controlled bytes outside the intended validated path before the final guarded replace step executes.
OpenClaw < 2026.3.13 - Telegram Bot Token Exposure in Media Fetch Error Logs
OpenClaw before 2026.3.13 contains an information disclosure vulnerability in the fetchRemoteMedia function that exposes Telegram bot tokens in error messages. When media downloads fail, the original Telegram file URLs containing bot tokens are embedded in MediaFetchError strings and leaked to logs and error surfaces.
