Summary
Account takeover vulnerability in the Simple History plugin for WordPress. An authenticated user (Subscriber+) can read full event context, including password reset keys, via event reaction endpoints.
Risk Assessment
An attacker can take over an administrator account by triggering a password reset and reading the reset key from the event log. Requires experimental features to be enabled by an administrator.
Recommendation
Update the Simple History plugin to the latest version. Consider disabling experimental features if not needed.

Original NVD description (English source)
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.
