Summary

CVE-2024-13146 is a high-severity CSRF (CWE-352) vulnerability in Fs-Code Booknetic. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Local Account (T1136.001); ranked at the 23.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SC-23 (Session Authenticity) and SI-10 (Information Input Validation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Local Account (T1136.001) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-23 Session Authenticity good match

prevent

Directly mitigates CSRF by requiring session authenticity mechanisms like anti-CSRF tokens to validate state-changing requests such as staff account creation.

SI-10 Information Input Validation good match

prevent

Ensures validation of inputs including CSRF tokens during staff account creation to prevent forged requests from succeeding.

SI-2 Flaw Remediation good match

prevent

Provides timely remediation of the specific flaw by patching the Booknetic plugin to version 4.1.5 or later, adding required CSRF protections.

MITRE ATT&CK Enterprise TechniquesAI

T1136.001 Local Account Persistence

Adversaries may create a local account to maintain access to victim systems.

Why these techniques?

CSRF vulnerability enables exploitation of a public-facing WordPress application (T1190) to create arbitrary local WordPress staff accounts with login and plugin manage permissions (T1136.001) without proper authentication checks.

NVD Description

The Booknetic WordPress plugin before 4.1.5 does not have CSRF check when creating Staff accounts, which could allow attackers to make logged in admin add arbitrary Staff members via a CSRF attack

Deeper analysisAI

CVE-2024-13146 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, affecting the Booknetic WordPress plugin in versions before 4.1.5. The flaw arises from the absence of CSRF checks during the creation of Staff accounts, enabling unauthorized modifications through forged requests. Published on 2025-03-26 with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), it poses a high-severity risk to WordPress sites using the vulnerable plugin.

An attacker can exploit this vulnerability remotely without privileges by crafting a malicious webpage or link that, when visited by a logged-in administrator, triggers a CSRF attack to create arbitrary Staff members. This grants the added accounts potentially elevated permissions within the Booknetic system, leading to high impacts on confidentiality, integrity, and availability. User interaction from the admin is required, but the low complexity and network accessibility make it practical for phishing or social engineering campaigns targeting site owners.

The WPScan advisory at https://wpscan.com/vulnerability/19cb40dd-53b0-46db-beb0-1841e385ce09/ details the issue, with mitigation achieved by updating to Booknetic version 4.1.5 or later, which introduces the necessary CSRF protections. Security practitioners should prioritize patching affected WordPress installations and advise admins to enable general CSRF defenses like token validation.
