Vulnerability from github – Published: 2026-03-09 19:54 – Updated: 2026-03-09 19:54

Summary
OpenClaw: Cross-account sender authorization expansion in `/allowlist ... --store` account scoping
Details

Summary

/allowlist ... --store resolved the selected channel accountId for reads, but store writes still dropped that accountId and wrote into the legacy unscoped pairing allowlist store.

Because default-account reads still merge legacy unscoped entries, a store entry intended for one account could silently authorize the same sender on the default account.

This is a real cross-account sender-authorization scoping bug. Severity is set to medium because exploitation requires an already-authorized user who can run /allowlist edits.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published version checked: 2026.3.2
  • Affected versions: <= 2026.3.2
  • Fixed on main: March 7, 2026 in 70da80bcb5574a10925469048d2ebb2abf882e73
  • Patched release: 2026.3.7

Details

The affected path was: - src/auto-reply/reply/commands-allowlist.ts:386-393 resolved accountId and read store state with it - src/auto-reply/reply/commands-allowlist.ts:697-702 and src/auto-reply/reply/commands-allowlist.ts:730-733 wrote store state without passing accountId - src/pairing/pairing-store.ts:231-234 and src/pairing/pairing-store.ts:534-554 still merged legacy unscoped allowlist entries into the default account

The fix scopes /allowlist ... --store writes to the resolved account and clears legacy default-account store entries on removal so legacy reads no longer create cross-account authorization bleed-through.

Impact

  • Vulnerability class: improper authorization scoping / incorrect authorization
  • Exploitation requires: an already-authorized sender who can run /allowlist edits
  • Security effect: unintended authorization expansion from one channel account into default

Fix Commit(s)

  • 70da80bcb5574a10925469048d2ebb2abf882e73 — scope /allowlist ... --store writes by account and clean up legacy default-account removals

Release Process Note

npm 2026.3.7 was published on March 8, 2026. This advisory is fixed in the released package.

Thanks @tdjackey for reporting.

GHSA-PM23-3PX3-QRH7

Vulnerability from github – Published: 2024-08-26 00:30 – Updated: 2024-09-12 21:32
VLAI
Details

A bug in the 9p authentication implementation within lib9p allows an attacker with an existing valid user within the configured auth server to impersonate any other valid filesystem user.

This is due to lib9p not properly verifying that the uname given in the Tauth and Tattach 9p messages matches the client UID returned from the factotum authentication handshake.

The only filesystem making use of these functions within the base 9front systems is the experimental hjfs disk filesystem, other disk filesystems (cwfs and gefs) are not affected by this bug.

This bug was inherited from Plan 9 and is present in all versions of 9front and is remedied fully in commit 9645ae07eb66a59015e3e118d0024790c37400da.

GHSA-PM77-X6JP-G9H6

Vulnerability from github – Published: 2026-10-13 21:37 – Updated: 2026-10-13 21:37
VLAI
Details

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability in setAffectations() that allows authenticated attackers to insert access-right records for a caller-supplied target space without verifying the caller has rights to that space. Attackers can assign access affectations to spaces outside their own reach, breaking tenant isolation and granting unauthorized access to restricted spaces.

Vulnerability from github – Published: 2026-03-30 15:32 – Updated: 2026-03-30 15:32
VLAI
Details

A vulnerability of authorization bypass through user-controlled key in the 'console-survey/api/v1/answer/{EVENTID}/{TIMESTAMP}/' endpoint. Exploiting this vulnerability would allow an unauthenticated attacker to enumerate event IDs and obtain the complete Q&A history. This publicly exposed data may include IDs, private URLs, private messages, internal references, or other sensitive information that should only be exposed to authenticated users. In addition, the leaked content could be exploited to facilitate other malicious activities, such as reconnaissance for lateral movement, exploitation of related systems, or unauthorised access to internal applications referenced in the content of chat messages.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

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
Architecture and Design

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.

No CAPEC attack patterns related to this CWE.
