python-pyzipper: pyzipper is a replacement for Python's zipfile that can read and write AES encrypted zip files
CVE-2026-44722 is fixed in python-pyzipper on 1 platform by DEBIAN-CVE-2026-44722 (version 0.4.0-1), released July 17, 2026. It is not reported as exploited. Patch Radar priority: Routine.
pyzipper is a replacement for Python's zipfile that can read and write AES encrypted zip files. Prior to 0.4.0, a Python operator precedence bug in pyzipper/zipfile_aes.py caused the AE-2 format to never be automatically selected during encryption, causing encrypted entries to be written in AE-1 format and exposing the plaintext CRC32 checksum in the ZIP header and, for unseekable zip archives, in the datadescripter section, allowing an attacker who possesses the archive to brute-force candidate plaintexts for small or low-entropy files by comparing CRC32 values. This issue is fixed in version 0.4.0.
