Details
Dmitry Tantsur and Tuomo Tanskanen discovered that Ironic did not
properly validate file paths when handling ISO images. A privileged
authenticated remote user could use this issue to perform path
traversal via a crafted ISO image and overwrite arbitrary files on
the Ironic conductor. (CVE-2026-48681)
Dmitry Tantsur and Tuomo Tanskanen discovered that Ironic did not
properly validate kernel command line parameters. A privileged
authenticated remote user could use this issue to inject
scripts during node boot and possibly execute arbitrary code.
(CVE-2026-46447)
Dmitry Tantsur and Tuomo Tanskanen discovered that Ironic
incorrectly restricted access to custom PXE templates. A privileged
authenticated remote user could use this issue to read arbitrary
sensitive files on the Ironic conductor. (CVE-2026-44917)
