Security readout for executives and security teams
Plain-English summary
Craft CMS sites in affected 3.x, 4.x, and 5.x releases can be exposed to remote code execution when PHP register_argc_argv is enabled. This is a critical, internet-reachable risk because exploitation needs no login or user interaction. CISA lists it as known exploited, so exposed sites should be treated as urgent remediation targets.
Executive priority
Treat this as immediate priority for any internet-facing Craft CMS estate. The issue enables remote code execution under a specific PHP setting, has critical severity, and is listed by CISA as known exploited. Remediation should be tracked as an incident-driven patching task, not routine maintenance.
Technical view
CVE-2024-56145 is a CWE-94 code injection issue in craftcms/cms. Affected ranges are 3.0.0 to before 3.9.14, 4.0.0-RC1 to before 4.13.2, and 5.0.0-RC1 to before 5.5.2, contingent on php.ini register_argc_argv being enabled. CVSS v4.0 is 9.3 with network, low-complexity, unauthenticated attack characteristics.
Likely exposure
Highest exposure is internet-facing Craft CMS deployments running affected versions with PHP register_argc_argv enabled. Sites already updated to 3.9.14, 4.13.2, or 5.5.2 are outside the named affected ranges. The provided sources do not identify specific hosting platforms or default configuration prevalence.
Exploitation context
Active exploitation is supported by CISA KEV listing. The source bundle also cites a public exploit repository, indicating public exploit material exists. The vendor advisory describes the RCE vector as unspecified, so this assessment should avoid assuming exact exploit mechanics beyond the documented configuration condition.
Researcher notes
Evidence supports affected versions, the register_argc_argv prerequisite, patch versions, CWE-94 classification, CVSS 9.3, CISA KEV status, and public exploit availability. The provided advisory does not disclose the precise RCE vector, affected configuration prevalence, or indicators of compromise.
Mitigation direction
- Upgrade Craft CMS to 3.9.14, 4.13.2, 5.5.2, or later.
- Disable PHP register_argc_argv where immediate upgrade is not possible.
- Prioritize internet-facing Craft CMS systems before internal-only instances.
- Review vendor guidance before applying compensating controls not listed here.
- After remediation, confirm the deployed Craft version and PHP setting.
Validation and detection
- Inventory Craft CMS versions across production, staging, and backups.
- Check php.ini for register_argc_argv on each Craft host.
- Confirm public-facing Craft sites are patched or have the setting disabled.
- Review CISA KEV status when assigning remediation deadlines.
- Look for post-exploitation indicators if exposure existed before remediation.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
