CVE-2025-67746
CWE-74Published: December 30, 2025· Updated: Jun 17, 2026
Official Description
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.
Technical Analysis
CVE-2025-67746 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
