Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-31678 is a missing authorization vulnerability, classified under CWE-862, in the Drupal AI (Artificial Intelligence) module that enables forceful browsing. This issue affects all versions of the AI module from 0.0.0 up to but excluding 1.0.3. The vulnerability carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H), indicating high severity primarily due to its potential for significant availability disruption.
Remote attackers require no privileges or user interaction and can exploit the flaw over the network with low attack complexity. Exploitation allows limited access to confidential information alongside high-impact denial of service, such as resource exhaustion or service disruption on affected Drupal sites running vulnerable AI module versions.
The official Drupal security advisory at https://www.drupal.org/sa-contrib-2025-004 details the issue and recommends updating the AI (Artificial Intelligence) module to version 1.0.3 or later as the primary mitigation.
This vulnerability occurs in a Drupal module handling artificial intelligence features, highlighting potential risks in AI-integrated web applications. No public information on real-world exploitation is available as of the CVE publication on 2025-03-31.

Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly requires enforcement of authorization decisions on every access request, structurally eliminating missing authorization checks.
AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.
AC-25 requires a tamperproof, always-invoked reference monitor that ensures authorization checks cannot be omitted.
AC-6 reduces the set of actions reachable without proper authorization, limiting blast radius of missing checks.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing authorization checks.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Requiring authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.
Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.
Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.
Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.
By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.
Defining authorization responsibilities and reviewing risk-treatment progress throughout the project lifecycle catches missing authorization checks before the system is deployed.
