OpenClaw: Incorrect Resource Transfer Between Spheres
CVE-2026-25253 is a high-severity incorrect resource transfer between spheres vulnerability in OpenClaw, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 2026.1.29 as the first without the flaw, so updating OpenClaw to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 32.4% chance of exploitation within 30 days, which is in the top 1.64% of all scored CVEs.
EPSS places it among the vulnerabilities most likely to be exploited soon.
What to do
- Update OpenClaw to 2026.1.29 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Incorrect Resource Transfer Between Spheres
The product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource.
