CVE-2026-30458, published on 2026-03-26, is a vulnerability in Daylight Studio FuelCMS version 1.5.2 that enables attackers to exfiltrate users' password reset tokens via a mail splitting attack. The issue carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating high severity due to its network accessibility, low attack complexity, lack of required privileges or user interaction, and significant impacts on confidentiality and integrity. It is classified under CWE-620.
Unauthenticated remote attackers can exploit this vulnerability over the network without privileges or user interaction. By conducting a mail splitting attack, they can steal password reset tokens, which may facilitate unauthorized access to user accounts, as suggested by the vulnerability's high integrity impact and related reporting on account takeover risks.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Re-authentication explicitly requires users to prove identity before performing sensitive actions such as password changes.
Authenticator management requires identity verification during password distribution and changes, directly stopping unverified password updates.

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.
Requires secure management of authentication information, directly addressing the need to verify the original password before allowing a change.
Mandates secure authentication mechanisms, which include verifying existing credentials before permitting password changes.
Identity management processes can incorporate verification steps, but the control itself does not explicitly require password-change verification.
Information access restriction can be strengthened by password verification, yet the control focuses on access rights rather than change procedures.
