GHSA-xc3w-ghxg-pw5f PUBLISHED

Record from GitHub Advisory Database · Published July 26, 2023

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.
