CVE-2023-34235

Strapi is an open-source headless content management system. Prior to version 4.10.8, it is possible to leak private fields if one is using the `t(number)` prefix. Knex query allows users to change the default prefix. For example, if someone changes the prefix to be the same as it was before or to another table they want to query, the query changes from `password` to `t1.password`. `password` is protected by filtering protections but `t1.password` is not protected. This can lead to filtering attacks on everything related to the object again, including admin passwords and reset-tokens. Version 4.10.8 fixes this issue.

### Summary Still able to leak private fields if using the t(number) prefix ### Details Knex query allows you to change there default prefix ```SqliteError: select distinct `t0`.* from `pages` as `t0` left join `admin_users` as `t1` on `t0`.`updated_by_id` = `t1`.`id` where (`t1`.`password` = 1)``` so if you change the prefix to the same as it was before or to an other table you want to query you query changes from password to t1.password password is protected by filtering protections but t1.password is not protected ### PoC 1 Create a contentType 2 add to its options "populateCreatorFields" 3 create 1 entity in your new content type 4 in settings enable the find route in settings for the content type you created for public 5 /api/(Your contenttype)?filters%5BupdatedBy%5D%5Bt1.password%5D%5B%24startsWith%5D=a%24 And now the api returns noting if you were to do /api/(Your contenttype)?filters%5BupdatedBy%5D%5Bt1.password%5D%5B%24startsWith%5D=%24 it would return your entity ### Impact You can do filtering attacks on everything related to the object again including admin passwords and reset-tokens.
