What an attacker can do
On POSIX systems an attacker with rename access in a non-sticky parent can swap those names to cause overwrite or unlink operations, while a writable adjacent hot journal is additionally required for attacker-chosen content overwrites. Vendor/CNA’s CVSS 3.1 assessment (base score 7.1/10) rates confidentiality impact as none; integrity and availability impact as high.
