Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Winter CMS's winter/wn-backend-module package versions before 1.2.13 are vulnerable to SQL injection through the numberrange filter scope in the Backend Filter widget when that scope uses the conditions key. An attacker needs a valid backend account with access to a list view where a plugin has registered such a scope, and could then read database contents. Upgrade to version 1.2.13, which contains the fix.
