CVE-2026-25645
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.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Since the file is visible and the application which is using the temp file could be known, the attacker has gained information about what the user is doing at that time.
