Deeper analysis

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.
