Description

Django vulnerable to privilege abuse in GenericInlineModelAdmin

An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. Add permissions on inline model instances were not validated on submission of forged POST data in GenericInlineModelAdmin.

Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.

Django would like to thank N05ec@LZU-DSLab for reporting this issue.
