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.

Why these techniques?

Direct RCE via unauthenticated input to eval() in public-facing WordPress plugin enables T1190 exploitation and T1505.003 web shell deployment.

NVD Description

The Product Addons for Woocommerce – Product Options with Custom Fields plugin for WordPress is vulnerable to Code Injection in all versions up to, and including, 3.1.0. This is due to insufficient input validation of the 'operator' field in conditional…

logic rules within the evalConditions() function, which passes unsanitized user input directly to PHP's eval() function. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to inject and execute arbitrary PHP code on the server via the conditional logic 'operator' parameter when saving addon form field rules.

Deeper analysisAI

CVE-2026-2296 is a code injection vulnerability affecting the Product Addons for WooCommerce – Product Options with Custom Fields plugin for WordPress, in all versions up to and including 3.1.0. The issue stems from insufficient input validation of the 'operator' field in conditional logic rules processed by the evalConditions() function, which passes unsanitized user input directly to PHP's eval() function. This flaw is classified under CWE-94 (Improper Control of Generation of Code) with 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).

Authenticated attackers with Shop Manager-level access or higher can exploit this vulnerability by injecting arbitrary PHP code through the conditional logic 'operator' parameter when saving addon form field rules. Successful exploitation allows remote code execution on the server, potentially leading to full compromise of the WordPress site, including high confidentiality, integrity, and availability impacts.

References provided include source code locations in the plugin's conditional-logic.php file (lines 84 and 104 in tags/3.0.19 and trunk versions), highlighting the eval() usage, along with a specific changeset (r3458823) in the WordPress plugin trac repository, which likely documents the patch addressing the input validation deficiency.
