CVE-2026-30459 is a high-severity Weak Password Recovery Mechanism for Forgotten Password (CWE-640) vulnerability in Thedaylightstudio Fuel Cms. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 18th 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 map to IA-12 (Identity Proofing) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-30459 affects the Forgot Password feature in Daylight Studio FuelCMS version 1.5.2. The vulnerability enables unauthenticated attackers to obtain a victim user's password reset token through a crafted link embedded in a valid email message. It carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:N) and maps to CWE-640.
Unauthenticated attackers (PR:N) can exploit this issue over the network with low complexity by sending a targeted email containing the crafted link. Successful exploitation requires user interaction (UI:R), such as the victim clicking the link, after which the attacker obtains the password reset token. This results in low confidentiality impact but high integrity impact, potentially allowing account compromise.

Mitigating Controls (NIST 800-53 r5) AI
Identity proofing at appropriate assurance levels ensures forgotten-password recovery cannot succeed without strong verification of the user.
Authenticator management requires secure distribution, reset, and verification procedures that directly address weak password recovery flows.
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.
Credential lifecycle management directly includes password reset/recovery flows.
Identity proofing is the core control that prevents weak or bypassed recovery mechanisms.
Authentication policy covers strength/MFA but does not address recovery path weaknesses.
Secure SDLC reduces implementation flaws but is not specific to password-recovery design.
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.
Strong authentication-information lifecycle rules directly address weak password-recovery flows.
Secure-SDLC practices can embed strong recovery design, yet the control is broader than this single weakness.
Application-security requirements can mandate secure recovery flows, but the control covers many other requirements.
Secure-coding standards can prevent weak recovery implementations, yet the control is wider in scope.
Secure-authentication requirements include robust forgotten-password procedures.
Proper access-rights provisioning can limit who can trigger recovery, but does not fix the recovery mechanism itself.
