CVE-2023-34235 | Leaking sensitive user information still possible by filtering on private with prefix fields

Exp

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.

Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
