CVE-2023-30179
Published: 13 June 2023
Summary
CVE-2023-30179 is a high-severity Code Injection (CWE-94) vulnerability in Craftcms Craft Cms. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 9.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CraftCMS version 3.7.59 contains a server-side template injection vulnerability tracked as CVE-2023-30179 and assigned CWE-94. The flaw resides in the User Photo Location setting within User Settings, where an authenticated user can supply a Twig template expression that is later evaluated by the application.
An attacker with administrative privileges can inject malicious Twig code into the photo location field to achieve remote code execution on the server. The CVSS 3.1 score of 7.2 reflects the requirement for high privileges and the resulting impact on confidentiality, integrity, and availability.
Vendor statements in the referenced GitHub advisory discussions dispute the issue as a vulnerability, noting that only administrators can supply the Twig code and that this capability is intentional by design. The CraftCMS changelog entry for version 4.4.2 and related advisory comments provide the primary mitigation context, indicating that the behavior is considered expected for privileged users.
EPSS remains flat at a low value of 0.0550 with no material increase after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
