OpenClaw: Improper Control of Interaction Frequency
CVE-2026-41346 is a high-severity improper control of interaction frequency vulnerability in OpenClaw, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 2026.3.31 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 0.42% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update OpenClaw to 2026.3.31 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.

Official description
OpenClaw 2026.2.26 before 2026.3.31 enforces pending pairing-request caps per channel file instead of per account, allowing attackers to exhaust the shared pending window. Remote attackers can submit pairing requests from other accounts to block new pairing challenges on unaffected accounts, causing denial of service.
