CVE-2021-29450: Debian Linux

Medium severity, CVSS 4.3. EPSS: 2.1% chance of exploitation in the next 30 days.

Wordpress is an open source CMS. One of the blocks in the WordPress editor can be exploited in a way that exposes password-protected posts and pages. This requires at least contributor privileges. This has been patched in WordPress 5.7.1, along with the older affected versions via minor releases. It's strongly recommended that you keep auto-updates enabled to receive the fix.

Affected products

• Debian Debian Linux: version 9.0 only; version 10.0 only
• WordPress WordPress: from 4.7, before 5.7.1 (fixed in 5.7.1)
