GHSA-PJVX-RX66-R3FG
Vulnerability from github – Published: 2026-03-09 19:54 – Updated: 2026-03-09 19:54Summary
/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 in70da80bcb5574a10925469048d2ebb2abf882e73 - 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
/allowlistedits - Security effect: unintended authorization expansion from one channel account into
default
Fix Commit(s)
70da80bcb5574a10925469048d2ebb2abf882e73— scope/allowlist ... --storewrites 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 21:32A 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.

Vulnerability from github – Published: 2026-03-30 15:32 – Updated: 2026-03-30 15:32A 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
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.
