Is CVE-2024-56145 (Craft CMS Code Injection) being exploited in the wild?

By NHI Mgmt Group Editorial Team Updated October 19, 2026 Domain: Cyber Security

Yes. CISA added CVE-2024-56145 to its Known Exploited Vulnerabilities catalogue on 2 June 2025, which it does only when there is reliable evidence of active exploitation. CISA has not linked it to known ransomware campaigns. Craft CMS contains a code injection vulnerability. Any organisation running the affected product should treat remediation as urgent. Check exposure first, then patch or mitigate, then review logs for signs of earlier compromise.

What makes CVE-2024-56145 urgent to check first?

This is a live exploitation question, so the first job is exposure confirmation, not a deep forensic project. If Craft CMS is present, treat any internet-facing instance as a priority until you know whether it is affected and whether the vulnerable code path is reachable. The operational rule is simple: confirm scope, then move immediately to remediation or mitigation.

For vulnerability triage and prioritisation, use the CISA KEV record and the vendor advisory as the authoritative starting points, and keep the question focused on whether the product is in service, exposed, and able to be reached in the current configuration. The Zero-Day and Exploited Vulnerabilities Guide is the right internal playbook for the response pattern here: KEV-driven triage, emergency mitigation, and post-patch hunting.

How should teams respond once exposure is confirmed?

Because the issue is code injection, the response should assume arbitrary server-side execution is the main business risk until proven otherwise. Patching or the vendor-recommended mitigation is the preferred path, but the practical decision is often whether the system can be taken out of service briefly to reduce blast radius. If the platform supports multiple environments, prioritise production first and avoid leaving a known-exploited internet-facing instance in place as a temporary workaround.

When organisations need a broader prioritisation model for vulnerability work, the Vulnerability Management Guide helps frame the decision around scope, remediation SLAs, exception handling, and verification rather than around the CVE number alone. For this specific case, the key judgement is that a confirmed exploited-in-the-wild flaw should move ahead of routine backlog work unless there is a stronger containment reason to delay.

What should be checked after patching or mitigation?

After remediation, review access logs, application logs, web server logs, and any available endpoint or EDR telemetry for signs that the system was already used as a foothold. With code injection, look for new files, unusual process execution, strange outbound connections, unexpected admin activity, and changes to application configuration or templates. If there is any chance the instance handled secrets, sessions, or privileged credentials, verify whether those values could have been exposed during the compromise window.

For readers dealing with web application attack paths more generally, the OWASP Top 10 remains a useful baseline for understanding how injection-style weaknesses turn into full application compromise. The relevant practitioner lesson here is that a successful patch does not close the incident by itself; you still need a compromise check proportionate to the likely impact of server-side code execution.

Risk and Threat Considerations

Code injection in a public CMS is attractive to attackers because it can convert a web application flaw into direct control of the hosting environment, data access, or follow-on credential theft. Once exploitation is confirmed in the wild, the main risk is no longer theoretical vulnerability presence but silent abuse before the patch lands.

Failure mechanism: An attacker reaches the vulnerable Craft CMS code path, injects malicious code, and uses the application context to execute commands, modify content, stage payloads, or pivot to adjacent systems.

Impact: This can lead to website defacement, data exposure, credential theft, persistence, and broader compromise of the underlying server or connected services.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

MITRE ATT&CK addresses the attack and risk surface, while CIS Controls v8, OWASP ASVS and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.

Framework	Control / Reference	Relevance
CIS Controls v8	CIS-7 — Continuous Vulnerability Management	Guides urgent triage and remediation of an actively exploited CMS flaw.
Recommendation — Prioritise, remediate, and verify exploited vulnerabilities before routine backlog work.
OWASP ASVS	V15 — Secure Coding and Architecture	Code injection is a core application-security failure affecting server-side execution paths.
Recommendation — Review injection-prone code paths and harden the application architecture against arbitrary execution.
NIST CSF 2.0	ID.RA-01 — Asset Vulnerability Identification	Exposure confirmation depends on identifying where the vulnerable CMS is deployed.
	RS.MA-01 — Incident Mitigation	Active exploitation requires rapid containment and remediation, not deferred action.
Recommendation — Identify affected assets and confirm which systems are exposed to the vulnerable product. Contain or remediate the vulnerable system immediately to reduce ongoing attack opportunity.
MITRE ATT&CK	T1190 — Exploit Public-Facing Application	The question concerns exploitation of an internet-facing CMS vulnerability.
Recommendation — Map the case to public-facing application exploitation and hunt for initial-access indicators.

Practitioner Guidance

What to prioritise: Treat externally reachable Craft CMS instances as the top priority until exposure is verified and remediation is complete. If you must choose between a fast patch and a slower containment exercise, favour the action that removes attacker reach first.

What to verify: Confirm the version, deployment path, and whether the instance is internet-facing, then verify post-fix state with log review and file integrity checks. If you cannot tell whether the system was touched, assume the attacker may have had enough time to act.

Practitioner takeaway: For a KEV-listed code injection flaw, the real decision is not whether to patch eventually, but how quickly you can close exposure and prove the system was not already used as an execution point.
