What’s new in PeaZip 11.4?
PeaZip 11.4.0 is a maintenance release that puts particular emphasis on security hardening. The project reports changes to filename validation, safer handling of variable input during archive tasks, range checking, and updated backend components. It also includes several interface and platform-specific fixes.
Safer archive operations
Archive tasks no longer launch a full command shell for operations that process variable input, reducing reliance on shell-based command execution.
Improved input validation
Filename sanitization and earlier validation checks help identify suspicious or invalid input before potentially risky operations proceed.
Updated compression backend
The release updates 7z/p7zip to 26.04 and the Pea component to 1.34.
Usability refinements
The file manager receives improved automatic refresh behavior, with a Windows shortcut-navigation improvement and a Linux default-setting fix.
Security improvements in PeaZip 11.4
1. Reduced use of command shells for archive tasks
The project says PeaZip no longer starts a full shell such as Bash on Linux or CMD on Windows for compression, extraction, and other tasks that accept variable input. Avoiding a shell in these backend operations can reduce exposure to command-injection patterns that arise when user-controlled values are interpreted as shell syntax. The text-only Console mode remains available.
2. Stronger filename sanitization
Filename validation has been improved at multiple stages of the scripting engine. The release notes describe earlier validation and warnings intended to help prevent dangerous operations and reduce false positives when names contain special characters.
3. Range checks and input-size validation
PeaZip 11.4 begins enabling range checking wherever practical while aiming to preserve performance. The project also reports work on validating input sizes for older archive formats that may encounter problems when processing large files.
Linux and Windows improvements
Linux: Quick delete default
On Linux, the option to delete files after archiving or extraction now defaults correctly to “Quick delete,” according to the release report.
File manager auto-refresh
The built-in file manager has been updated to refresh automatically more reliably, improving the experience when browsing folders and working with files.
Windows: Browse .lnk shortcut targets
On Windows, users can navigate to the target of a .lnk shortcut from PeaZip’s file browser. The release notes describe using Ctrl + P or the “Explore path (PeaZip)” option in the Navigation menu. This opens the target directory in PeaZip, or the parent directory when the shortcut points to a file, rather than launching the shortcut itself.
