CVE-2020-4050 (GCVE-0-2020-4050)

Vulnerability from cvelistv5 – Published: 2020-06-12 16:00 – Updated: 2024-08-04 07:52

Title

set-screen-option filter misuse by plugins leading to privilege escalation in WordPress

Summary

In affected versions of WordPress, misuse of the `set-screen-option` filter's return value allows arbitrary user meta fields to be saved. It does require an admin to install a plugin that would misuse the filter. Once installed, it can be leveraged by low privileged users. This has been patched in version 5.4.2, along with all the previously affected versions via a minor release (5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34).

Severity

3.5 (Low)
