composer: Composer is a dependency manager for PHP
CVE-2025-67746 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2025-67746, released December 30, 2025. It is not reported as exploited. Patch Radar priority: Routine.
Composer is a dependency manager for PHP. In versions on the 2.x branch prior to 2.2.26 and 2.9.3, attackers controlling remote sources that Composer downloads from might in some way inject ANSI control characters in the terminal output of various Composer commands, causing mangled output and potentially leading to confusion or DoS of the terminal application. There is no proven exploit and this has thus a low severity but we still publish a CVE as it has potential for abuse, and we want to be on the safe side informing users that they should upgrade. Versions 2.2.26 and 2.9.3 contain a patch for the issue.
