How severe is CVE-2024-56145?

No CVSS score has been assigned to CVE-2024-56145 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2024-56145?

CVE-2024-56145 affects the following packages: craftcms/cms (Packagist), craftcms/cms (Packagist), craftcms/cms (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2024-56145?

Update craftcms/cms to 5.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-56145 is resolved across your whole dependency graph.

How do I detect CVE-2024-56145 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-56145 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2024-56145 actively exploited in the wild?

Yes. There are 3 known exploit references for CVE-2024-56145, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2024-56145?

CVE-2024-56145 has an EPSS (Exploit Prediction Scoring System) score of 97.4%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2024-56145 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2024-56145 (Craft CMS Code Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2025-06-02. CISA required all US federal civilian agencies to remediate this vulnerability by 2025-06-23. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2024-56145?

CVE-2024-56145 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for CVE-2024-56145?

A Nuclei detection template exists for CVE-2024-56145, meaning automated scanners can fingerprint it. A Metasploit module references CVE-2024-56145, which lowers the barrier to weaponization. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2024-56145 published, and has it been updated?

CVE-2024-56145 was published on December 18, 2024 and was last updated on October 22, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Exploitation Status

Actively exploited in the wild

Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2025-06-02. Federal agencies were required to remediate by 2025-06-23.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.

Description

Craft is a flexible, user-friendly CMS for creating custom digital experiences on the web and beyond. Users of affected versions are affected by this vulnerability if their php.ini configuration has register_argc_argv enabled. For these users an unspecified remote code execution vector is present. Users are advised to update to version 3.9.14, 4.13.2, or 5.5.2. Users unable to upgrade should disable register_argc_argv to mitigate the issue.

How to detect CVE-2024-56145

A community-maintained Nuclei template exists for this CVE. You can scan for it directly:

nuclei -id cve-2024-56145 -u https://target

Template: Craft CMS - Remote Code Execution via Template Path Manipulation
Severity: critical
Impact: Successful exploitation of this vulnerability could allow an unauthenticated attacker to perform remote code execution.
Remediation: Upgrade CraftCMS to either >5.5.2 or >4.13.2 or >3.9.14. Or If you can't upgrade yet, and register_argc_argv is enabled, you can disable it to mitigate the issue.
