CVE-2026-84792: Craft CMS CMS

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

Craft CMS versions before 5.10.11 contain a broken access control vulnerability in the element-indexes/save-elements endpoint that allows control panel users to move entries into sections they cannot edit. Attackers with limited section permissions can relocate or publish entries to unauthorized sections by overwriting the sectionId attribute after initial authorization checks, bypassing the destination section permission validation.

Affected products

• Craft CMS CMS: from 5.0.0-RC1, before 5.10.11 (fixed in 5.10.11)
