CVE-2026-100539

OpenClaw (npm package 'openclaw') before 2026.8.1 fails to revoke memory tool access when an operator hot-disables memory configuration. Existing memory_search and memory_get tool instances retain the enabled configuration captured at creation time because the execution-time resolver treats explicit disablement like an unavailable configuration snapshot and restores the stale authority. As a result, during an already-running agent turn the model can continue searching and reading durable memory after the operator revoked that access, for the remainder of that run. Exploitation requires memory to be disabled while a previously created memory tool remains active. The issue is fixed in 2026.8.1.

What this means for your business

  • An attacker can use it remotely, over a network, with an ordinary user login, but only after tricking someone into an action such as opening a file or a link.
  • FIRST's prediction model gives it a 0.2% chance of attack attempts being seen in the next 30 days, ranking above 9% of all known flaws.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
