Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates the CVE by requiring timely identification, reporting, and remediation of the CSRF flaw in the Drupal Cache Utility module via patching to version 1.2.1.

SC-23 Session Authenticity good match

prevent

Enforces session authenticity mechanisms such as anti-CSRF tokens to prevent forged requests from malicious sites exploiting authenticated users.

SI-10 Information Input Validation good match

prevent

Requires validation of all inputs, including requests to the Cache Utility module, to reject forged CSRF requests lacking proper tokens or origins.

NVD Description

Cross-Site Request Forgery (CSRF) vulnerability in Drupal Cache Utility allows Cross Site Request Forgery.This issue affects Cache Utility: from 0.0.0 before 1.2.1.

Deeper analysisAI

CVE-2025-31690 is a Cross-Site Request Forgery (CSRF) vulnerability, mapped to CWE-352, in the Drupal Cache Utility module. This issue affects all versions of Cache Utility from 0.0.0 up to but not including 1.2.1. The vulnerability carries 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), reflecting its high severity due to network accessibility, low complexity, lack of prerequisite privileges, and potential for significant impacts across confidentiality, integrity, and availability.

Attackers can exploit this vulnerability remotely by crafting malicious web pages or links that, when visited by an authenticated Drupal user, trigger forged requests to the Cache Utility module. No special privileges are required on the attacker's part, though user interaction is necessary to lure victims to the malicious content. Successful exploitation allows the attacker to perform unauthorized cache-related operations on behalf of the victim, potentially compromising sensitive data, modifying site behavior, or disrupting service availability.

The Drupal security advisory at https://www.drupal.org/sa-contrib-2025-019 details the vulnerability and recommends updating the Cache Utility module to version 1.2.1 or later as the primary mitigation. Administrators should verify installations and apply the patch promptly to prevent exploitation.
