https://notcve.org/view.php?id=CVE-2022-26488
07 Mar 2022 — In Python before 3.10.3 on Windows, local users can gain privileges because the search path is inadequately secured. The installer may allow a local attacker to add user-writable directories to the system search path. To exploit, an administrator must have installed Python for all users and enabled PATH entries. A non-administrative user can trigger a repair that incorrectly adds user-writable paths into PATH, enabling search-path hijacking of other users and system services. This affects Python (CPython) t... • https://github.com/techspence/PyPATHPwner • CWE-426: Untrusted Search Path •

CVE-2022-0391 – python: urllib.parse does not sanitize URLs containing ASCII newline and tabs
https://notcve.org/view.php?id=CVE-2022-0391
09 Feb 2022 — 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. • https://bugs.python.org/issue43882 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

CVE-2021-3733 – python: urllib: Regular expression DoS in AbstractBasicAuthHandler
https://notcve.org/view.php?id=CVE-2021-3733
17 Sep 2021 — There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. Se presenta un fallo en la clase AbstractBasicAuthHandler de urllib.

CVE-2021-3426 – python: Information disclosure via pydoc
https://notcve.org/view.php?id=CVE-2021-3426
03 May 2021 — There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7.
