Ironic: Improper Protection of Alternate Path

Published Updated By the CyberSecBulletin desk

CVE-2026-54423 is a high-severity improper protection of alternate path vulnerability in Ironic from OpenStack, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists versions 29.0.6, 32.0.2, 35.0.2 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 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
