How to Fix CVE-2024-24821
To remediate this vulnerability, upgrade all affected Composer/composer dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade composer/composer to 2.2.23Upgrade composer/composer to 2.7.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for composer/composerHow to Check if You Are Affected
To determine whether your application is affected by CVE-2024-24821, inspect your project dependencies for Composer/composer:
inspect dependencies for composer/composerAnalyze the terminal output to locate any version of Composer/composer in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.23), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-829: Inclusion of Functionality from Untrusted Control Sphere, where the product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.

"details" : "### Impact\n\nSeveral files within the local working directory are included during the invocation of Composer and in the context of the executing user.\n\nAs such, under certain conditions arbitrary code execution may lead to local privilege escalation, provide lateral user movement or malicious code execution when Composer is invoked within a directory with tampered files.\n\nAll Composer CLI commands are affected, including composer.phar's self-update.\n\nThe following are of high risk:\n\n- Composer being run with sudo.\n- Pipelines which may execute Composer on untrusted projects.\n- Shared environments with developers who run Composer individually on the same project.\n\n### Patches\n\n2.7.0, 2.2.23\n\n### Workarounds\n\n- It is advised that the patched versions are applied at the earliest convenience.\n\nWhere not possible, the following should be addressed:\n- Remove all sudo composer privileges for all users to mitigate root privilege escalation. \n- Avoid running Composer within an untrusted directory, or if needed, verify that the contents of `vendor/composer/InstalledVersions.php` and `vendor/composer/installed.php` do not include untrusted code. \n\nA reset can also be done on these files by the following:\n\n```sh\nrm vendor/composer/installed.php vendor/composer/InstalledVersions.php\ncomposer install --no-scripts --no-plugins\n```",
