Threats tagged 'bit-composer-2026-40176'

Composer, a PHP dependency manager, contains a command injection vulnerability in versions 1.0 through 2.2.26 and 2.3 through 2.9.5. The vulnerability exists in the Perforce::generateP4Command() method, which improperly escapes user-supplied Perforce connection parameters. An attacker can exploit this by crafting a malicious composer.json file declaring a Perforce VCS repository, leading to arbitrary command execution with the privileges of the user running Composer. This issue cannot be exploited through composer.json files of dependencies, only from the root composer.json or composer config directory. The vulnerability is fixed in versions 2.2.27 and 2.9.6.
