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.
