Summary

CVE-2026-7459 is a high-severity Weak Password Recovery Mechanism for Forgotten Password (CWE-640) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 47th 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 IA-12 (Identity Proofing) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data

The Simple History – Track, Log, and Audit WordPress Changes plugin for WordPress is vulnerable to authenticated (Subscriber+) account takeover in all versions up to, and including, 5.26.0 via the event reaction endpoints (react_to_event() / unreact_to_event()). The endpoints register get_items_permissions_check()…

as their permission_callback, which only verifies the requester is logged in and does not enforce the per-logger capability checks normally applied by Log_Query. As a result, a Subscriber-level user can POST to /wp-json/simple-history/v1/events/<id>/react with the _fields=context query parameter and read the full context of any Simple History event — including SimpleUserLogger entries that record the full password-reset email body (reset URL with the reset key) for any user. The attacker triggers a password reset for an administrator via the lost-password form, brute-forces recent event IDs through the reaction endpoint to read the resulting user_requested_password_reset_link event, extracts the reset key from context.message, and completes the password reset to take over the administrator account. Exploitation requires an administrator to have first enabled the experimental features option (simple_history_experimental_features_enabled), which is not the default.

Mitigating Controls

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.
