Summary

CVE-2026-22354 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 36.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-22354 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the Dotstore WooCommerce Category Banner Management plugin (banner-management-for-woocommerce) for WordPress. The flaw allows Object Injection and affects the plugin from unspecified initial versions through 2.5.1.

The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). It can be exploited remotely by an authenticated attacker with low privileges, such as a standard WordPress user role, requiring low attack complexity and no user interaction. Exploitation enables high-impact compromise of confidentiality, integrity, and availability, typically through arbitrary object instantiation leading to potential code execution.

Mitigation details are documented in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/banner-management-for-woocommerce/vulnerability/wordpress-woocommerce-category-banner-management-plugin-2-5-1-php-object-injection-vulnerability?_s_id=cve.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Timely patching or updating of the vulnerable WooCommerce Category Banner Management plugin directly remediates the deserialization of untrusted data flaw.

SI-10 Information Input Validation good match
prevent

Validates and sanitizes untrusted inputs to prevent object injection via unsafe deserialization in the plugin.

SI-16 Memory Protection partial match
prevent

Memory protection mechanisms like non-executable memory and ASLR mitigate potential remote code execution from object injection exploitation.
