What is CVE-2023-34235?
CVE-2023-34235 is a high-severity vulnerability in strapi, published on 25 Jul 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-200
