OpenClaw (npm package 'openclaw') versions >= 2026.4.5 and < 2026.8.1 can lose the originating requester's restrictions and untrusted provenance… (CVE-2026-100535)
OpenClaw npm package versions from 2026.4.5 up to but not including 2026.8.1 have a vulnerability where session-derived text persisted to session memory can lose the originating requester's restrictions and untrusted provenance. This allows a restricted external sender to persist instructions that may later be executed by a background agent with broader capabilities, potentially performing unauthorized actions. The vulnerability is fixed in version 2026.8.1.
AI Analysis
Technical Summary
OpenClaw (npm package 'openclaw') versions >= 2026.4.5 and < 2026.8.1 contain a vulnerability where session-derived text persisted to session memory can lose the original requester's restrictions and untrusted provenance. In deployments with session-memory capture and dreaming enabled, a restricted external sender's messages admitted with limited tools can persist instructions that are later processed by an unattended background (dreaming) agent with broader file and command capabilities. This can lead to actions beyond the original authority, affecting files, commands, or services accessible to that agent. Exploitation requires the content to be captured, selected for later processing, and followed by the model. The issue is resolved in version 2026.8.1.
Potential Impact
An attacker with limited privileges can cause a background agent with broader capabilities to execute unauthorized actions by persisting instructions through session memory. This can lead to high impact including confidentiality, integrity, and availability violations as indicated by the CVSS score of 7.5 (high).
Mitigation Recommendations
Upgrade OpenClaw to version 2026.8.1 or later where this vulnerability is fixed. No other mitigation or temporary workaround is indicated.
