Description

A security bypass flaw was found in Curl, which can be triggered by saving HSTS data to an excessively long file name. This issue occurs due to an error in handling HSTS long file names, leading to the removal of all contents from the file during the save process, and may allow a remote attacker to send a specially crafted request to use files without awareness of the HSTS status and enable a Man-in-the-Middle (MitM) attack.
