GHSA-WMWX-JR2P-4J4R
Vulnerability from github – Published: 2026-06-19 19:35 – Updated: 2026-06-19 19:35Impact
A relation query using the $relatedTo operator could read the membership of a Relation field even when that field was hidden from the requesting client by protectedFields, and even when the object owning the relation was not readable by the client under its ACL or class-level permissions. The request requires only the public API credentials that Parse clients normally carry — no user session, master key, or Cloud Code is needed.
As a result, an unauthenticated client who knows or obtains the owning object's objectId could enumerate the objects linked through a protected relation, or combine the operator with an objectId constraint to use it as a membership oracle — confirming whether a specific object is linked to a private parent. This affects applications that rely on protectedFields or object ACLs to keep Relation membership confidential, such as private group memberships, block lists, or account-to-resource associations.
Patches
The relation query path now authorizes $relatedTo against the owning object before reading the relation join table, using the caller's authentication context. The relation key is checked against the owning class's protectedFields (the query is rejected if the key is protected), and the owning object must be readable by the caller under its class-level permissions, ACL, and pointer permissions; otherwise the relation returns no results. Master and maintenance requests are unaffected. The check is applied consistently whether $relatedTo is used at the top level or nested within $or, $and, or $nor.
Workarounds
There is no complete workaround without upgrading. As mitigation, applications can avoid exposing sensitive membership through Relation fields to untrusted clients, or enforce access on the queried class in a beforeFind trigger.

Vulnerability from github – Published: 2026-03-03 23:12 – Updated: 2026-03-30 13:18Summary
channels.*.groups.*.toolsBySender could match a privileged sender policy using a colliding mutable identity value (for example senderName or senderUsername) when deployments used untyped keys.
The fix introduces explicit typed sender keys (id:, e164:, username:, name:), keeps legacy untyped keys on a deprecated ID-only path, and adds regression coverage to prevent cross-identifier collisions.
Affected Packages / Versions
- Package: npm
openclaw - Affected versions:
<= 2026.2.21-2 - Latest published npm version at triage time (February 22, 2026):
2026.2.21-2 - Patched version (planned next release):
2026.2.22
Impact
This is a sender-authorization bypass in group tool policy matching for deployments that use toolsBySender with untyped keys. Under those conditions, an attacker could inherit stronger tool permissions intended for another sender if they can force an identifier collision.
Fix Commit(s)
5547a2275cb69413af3b62c795b93214fe913b57
Release Process Note
patched_versions is pre-set to the planned next release (2026.2.22). Once that npm release is published, this advisory should only need publishing.

Mitigation
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
