Threat & Defense at a Glance
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.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
PHP object injection (deserialization) RCE in a public-facing WordPress plugin directly enables T1190 for initial access via the vulnerable application and T1059.004 for arbitrary Unix shell command execution on the server.

Deeper analysisAI
CVE-2026-25316 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the Brainstorm Force CartFlows WordPress plugin, which allows Object Injection. Published on 2026-02-19, this issue affects CartFlows versions from n/a through 2.1.19 and carries 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).
The vulnerability can be exploited over the network by an attacker with high privileges, such as an authenticated administrator, requiring low complexity and no user interaction. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary code execution or other severe effects through the object injection.
The Patchstack advisory details this PHP Object Injection vulnerability in the WordPress CartFlows plugin version 2.1.19, with mitigation guidance available at https://patchstack.com/database/Wordpress/Plugin/cartflows/vulnerability/wordpress-cartflows-plugin-2-1-19-php-object-injection-vulnerability?_s_id=cve.
