CVE-2026-32282
CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Root.Chmod (affected versions not specified)
Description
On Linux, if the target of Root.Chmod is replaced with a symlink during a chmod operation, the operation can affect the symlink's target, even if that target is outside the root directory. The Linux fchmodat syscall does not respect the AT SYMLINK NOFOLLOW flag, which Root.Chmod uses to prevent symlink traversal. Root.Chmod verifies its target before proceeding and returns an error if the target is a symlink outside the root, but this check can be bypassed if the target is replaced with a symlink between the check and the operation.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
