CVE-2024-9681

A vulnerability was found in curl. When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache entry, making it end sooner or later than intended.

This flaw has been classified with a low severity primarily because it requires user interaction and a connection to a malicious subdomain. Additionally, this issue is only triggered when an HSTS cache file is being used with specific configurations when connecting to a malicious subdomain. This feature is enabled via the '--hsts' command line option. Furthermore, this issue will only cause parent domains that support HSTS for a short period of time and want to revert to HTTP to become inaccessible.
