Summary

CVE-2025-4607 is a critical-severity Use of Insufficiently Random Values (CWE-330) vulnerability in Wordpress (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Forge Web Credentials (T1606); ranked at the 43th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-12 (Cryptographic Key Establishment and Management) and SC-13 (Cryptographic Protection) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The PSW Front-end Login & Registration plugin for WordPress is vulnerable to privilege escalation in all versions through 1.12. The flaw resides in the customer_registration() function and stems from use of a weak, low-entropy OTP mechanism inside the forget() function (CWE-330), enabling unauthenticated attackers to trigger password resets for arbitrary accounts.

An attacker with no credentials can request a password reset for any user, including site administrators, and complete the reset to obtain full administrative control and site takeover. The vulnerability carries a CVSS 3.1 base score of 9.8 reflecting network-exploitable impact on confidentiality, integrity, and availability without authentication or user interaction.

Public references include the plugin source files on WordPress Trac that contain the affected functions, the plugin directory page, and a detailed entry from Wordfence. The associated EPSS score has remained flat at 0.0106 with no material rise since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

SC-12 Cryptographic Key Establishment and Management good match

SC-12 requires proper cryptographic key establishment and management, which structurally mandates use of sufficient randomness for key generation.

SC-13 Cryptographic Protection partial match

SC-13 requires selection and implementation of approved cryptographic algorithms and methods, which inherently depend on and enforce sufficiently random values.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly enforce use of cryptographically strong RNGs and catch insufficient randomness during design, coding, and testing.

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.

A.8.24 Use of cryptography mostly match
prevents

Cryptographic controls require use of approved, sufficiently random values for keys and nonces.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect weak randomness but does not prescribe the control itself.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC processes include verification steps that can catch insufficient randomness but do not directly specify RNG requirements.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly prohibit use of weak or predictable random number generators.

A.8.5 Secure authentication partial match
degrades

Secure authentication mechanisms depend on unpredictable values (nonces, salts, session tokens) to resist guessing.
