OpenClaw < 2026.4.29 - Session Visibility Check Bypass in Shared Memory Search

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

OpenClaw before 2026.4.29 contains a session visibility check bypass vulnerability in shared memory search that allows authenticated callers to access memory entries without proper authorization. Attackers can skip session visibility guards on the search path to retrieve memory entries that should not be visible to their session.

### Summary memory-wiki shared search could miss session visibility checks. In affected versions, a caller able to search shared memory could skip the session visibility guard on the affected search path. This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed. ### Impact When the affected feature is enabled and reachable, this could return memory entries that should not have been visible to that session. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. ### Patched Versions The first stable patched version is `2026.4.29`. ### Mitigations limit shared memory search to trusted operators until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
