Deeper analysis AI-assisted summary

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

CVE-2023-47840 is a code injection vulnerability (CWE-94) affecting the Qode Essential Addons plugin for WordPress, versions through 1.5.2. The flaw carries a CVSS 3.1 score of 9.9 and permits improper control over code generation, which manifests in practice as the ability to install and activate arbitrary plugins.

An attacker with low-privileged authenticated access can exploit the issue over the network without user interaction. Successful exploitation allows installation and activation of attacker-chosen plugins, resulting in arbitrary code execution with impact across confidentiality, integrity, and availability, including scope change to other site components.

The referenced Patchstack advisories document the vulnerability as an arbitrary plugin installation and activation issue but do not detail specific patches or configuration workarounds beyond the implied need to update the affected plugin.

EPSS for the CVE stands at 0.2119 with no material rise after disclosure.

Likely Mitigating Controls AI

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.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

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.
