Summary

CVE-2024-28116 is a high-severity Code Injection (CWE-94) vulnerability in Getgrav Grav. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Template Injection (T1221); ranked in the top 8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Grav is an open-source flat-file content management system affected by a server-side template injection vulnerability in versions prior to 1.7.45. The flaw, tracked under CWE-94 and CWE-1336, permits an authenticated user to inject and execute arbitrary code on the server by bypassing the existing security sandbox, resulting in a CVSS 3.1 score of 8.8.

Any user holding at least editor permissions can exploit the issue over the network without user interaction to achieve full code execution, compromising confidentiality, integrity, and availability of the remote server.

The official GitHub Security Advisory GHSA-c9gp-64c4-2rrh and accompanying commits document the patch that was merged into version 1.7.45; administrators are advised to upgrade immediately to close the injection path.

The EPSS score for this CVE stands at 0.6217 with no indicated rise after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

Security engineering principles require use of safe templating APIs and proper escaping of external input.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

finds

Security testing can detect template-injection flaws but does not itself implement neutralization controls.

prevents

Secure development life cycle mandates input validation and sanitization that directly prevents template-injection weaknesses.

prevents

Application security requirements explicitly call for neutralizing special elements in template engines.

prevents

Secure architecture principles reduce the likelihood of unsafe template processing but do not prescribe specific neutralization techniques.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
