Vulnerability AssessmentAI

Risk Assessment	Risk assessment is constrained by the absence of CVSS score, CVSS vector, and EPSS probability data. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker targeting a Drupal installation with Login Disable module <2.1.3 recognizes that the login form is restricted but discovers an alternate authentication path—such as REST API authentication, programmatic token generation, or a legacy authentication endpoint—that is not subject to the login-disable restriction. The attacker uses this alternate path to obtain valid session credentials or API tokens, effectively bypassing the intended login restriction without requiring knowledge of user passwords or exploitation of complex cryptographic flaws. …
Remediation	Immediately upgrade the Drupal Login Disable module to version 2.1.3 or later, following the patch released in the official Drupal security advisory at https://www.drupal.org/sa-contrib-2026-008. … Detailed patch versions, workarounds, and compensating controls in full report.
