OpenClaw before 2026.3.28 contains an execution approval vulnerability in exec-approvals-allowlist.ts that allows allow-always persistence to trust wrapper carrier executables instead of invoked targets. Attackers can exploit positional carrier executable routing through dispatch wrappers to establish broader allowlist entries than intended, weakening execution approval boundaries.

** UNSUPPORTED WHEN ASSIGNED ** Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Pony Mail leading to admin account takeover.
This issue affects all versions of the Lua implementation of Pony Mail. There is a Python implementation under development under the name "Pony Mail Foal" that is not affected by this issue, but hasn't been released yet.
As the Lua implementation of this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.
NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
