CVE-2022-0391 Functions in the urllib.parse module did not sanitize URLs to remove newline characters, which could lead to injection attacks. CVE-2025-0938 Functions in the urllib.parse and urlparse modules accepted domain names containing square brackets, which isn't valid. These delimiters are only permitted for IPv6 and IPvFuture hosts. This problem could result in differential parsing between the Python URL parser and other specification-compliant URL parsers. CVE-2025-1795 The implementations of e-mail header parsing and folding would encode the comma used to separate list items, which could cause receiving applications to interpret two items in the list as though they were one item. For Debian 11 bullseye, these problems have been fixed in version 3.9.2-1+deb11u3. We recommend that you upgrade your python3.9 packages.
