Ironic: Incorrect Resource Transfer Between Spheres
CVE-2026-42997 is a high-severity incorrect resource transfer between spheres vulnerability in Ironic from OpenStack, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 26.1.6, 29.0.5, 32.0.1 as the first without the flaw, so updating Ironic to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.43% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

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.
