Description
A flaw was found in the requests HTTP library, specifically in the requests.utils.extract_zipped_paths() function, which is used to load Certificate Authority (CA) bundles. A local attacker can exploit this vulnerability by pre-creating a malicious CA bundle file in the system's temporary directory. When a vulnerable application initializes the requests library, it may load this malicious file instead of the legitimate CA bundle, leading to a bypass of security controls and potential integrity compromise.
