CVE-2026-100535OpenClaw before 2026.8.1 Privilege Escalation via Session Memory
High 7.5
In plain English
A high-severity incorrect authorization in OpenClaw from OpenClaw. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 18% of all known vulnerabilities).
Official description
OpenClaw (npm package 'openclaw') versions >= 2026.4.5 and < 2026.8.1 can lose the originating requester's restrictions and untrusted provenance when session-derived text is persisted to session memory. In deployments where session-memory capture and dreaming are enabled, a restricted external sender whose messages are admitted with limited tools can persist instructions that are later supplied to an unattended background (dreaming) agent holding broader file and command capabilities, allowing actions beyond the authority of the original turn and affecting files, commands, or services available to that agent. Exploitation requires the content to be captured, selected for later processing, and followed by the model. The issue is fixed in 2026.8.1.
