Composer Multiple Vulnerabilities Allow Remote Code Execution

CERT-Bund disclosed multiple vulnerabilities in Open Source Composer, a widely used PHP dependency manager, that allow remote attackers to execute arbitrary code. Affected versions are below 2.9.6 and below 2.2.27 LTS. The vulnerabilities carry a CVSS Base Score of 8.8 and a Temporal Score of 7.7, indicating high severity.

Organizations using Composer in PHP development environments should update to the latest patched versions immediately and review dependency configurations to prevent exploitation. As the vulnerabilities enable full remote code execution, exposure could allow attackers to compromise servers, steal data, or pivot to other systems.
