Actively exploited in the wild — prioritise confirming exposure.

Why Medium

Medium rather than High: exposure is scored at a default because we cannot see your systems or suppliers. If you run or depend on Chef Infra Client, treat it as High.

Briefing

  • Do not treat uncorroborated claims as confirmed breaches.

Questions to ask IT

  • Do we run Chef Infra Client, and which versions?
  • Is any of it reachable from the internet?
  • Have we checked whether it has already been used against us?
  • If it is not yet patched, what mitigation is in place, and will the fix be done by 16 Nov?

Next steps

  1. Confirm exposure, mitigation status and any service interruption risk.

Summary

If the payload is executed or installed by the updater, this may result in arbitrary code execution in the context of the updating process or user.
  • CVE-2026-3502 is listed in known-exploited catalogue (exploitation in the wild)
