Composer 2.10.2
Composer 2.10.2 delivers multiple security fixes: package name validation, protection against path traversal in bin paths, sanitization of credentials in verbose output, stricter redirect handling, and prevention of phar metadata unserialization. Additional changes include retry logic for GitHub downloads, improved audit output, self-update warnings for EOL versions, and several bug fixes.
Composer 2.10.2 was released on July 1, 2024, introducing multiple security enhancements alongside performance and usability improvements. The release addresses five critical security concerns: package name validation to prevent malicious naming exploits, protection against path traversal attacks in binary file paths, removal of credentials from verbose output to avoid accidental exposure, stricter handling of HTTP redirects to prevent exploitation, and prevention of arbitrary code execution through PHAR metadata unserialization.
Beyond security fixes, the release improves download reliability with new retry logic specifically for GitHub sources, enhancing the robustness of dependency fetching. The audit command output has been refined for better clarity and actionability. Additionally, Composer now displays warnings when attempting to self-update to end-of-life versions, prompting users to upgrade to supported releases. The release includes several bug fixes addressing stability and correctness issues reported by the community.
