CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L

CVE-2023-32001
libcurl can be told to save cookie, HSTS and/or alt-svc data to files. When doing this, it called `stat()` followed by `fopen()` in a way that made it vulnerable to a TOCTOU race condition problem. An attacker could trick the victim to create or overwrite protected files holding this data in ways it was not intended to.
