Vulnerability Details : CVE-2023-32001
Potential exploit
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.
By exploiting this flaw, an attacker could trick the victim to create or
overwrite protected files holding this data in ways it was not intended to.
