Threat & Defense Details

Likely Mitigating ControlsAI

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.

SC-34 Non-modifiable Executable Programs

addresses: CWE-94

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

SC-44 Detonation Chambers

addresses: CWE-94

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

SI-10 Information Input Validation

addresses: CWE-94

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

SI-16 Memory Protection

addresses: CWE-94

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

NVD Description

Shopware is an open commerce platform. From 6.7.0.0 to before 6.7.6.1, a regression of CVE-2023-2017 leads to an array and array crafted PHP Closure not checked being against allow list for the map(...) override. This vulnerability is fixed in 6.7.6.1.

Deeper analysisAI

CVE-2026-23498 is a code injection vulnerability (CWE-94) affecting Shopware, an open commerce platform. It stems from a regression of CVE-2023-2017 in versions 6.7.0.0 through 6.7.6.0, where an array-crafted PHP Closure is not properly checked against an allow list in the map(...) override function. The issue has a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) and was published on 2026-01-14.

An authenticated attacker with high privileges, such as an administrator, can exploit this vulnerability remotely with low complexity and no user interaction required. Successful exploitation allows high-impact compromise, including unauthorized access to sensitive data (C:H), modification of system integrity (I:H), and disruption of availability (A:H), potentially leading to full server control within the affected scope.

Shopware's security advisory (GHSA-7cw6-7h3h-v8pf) and the fixing commit (3966b05590e29432b8485ba47b4fcd14dd0b8475) confirm the vulnerability is patched in version 6.7.6.1. Security practitioners should prioritize upgrading affected Shopware instances to 6.7.6.1 or later to mitigate the risk.
