CVE-2022-0391
The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1, 3.9.5, 3.8.11, 3.7.11 and 3.6.14.
