CVE-2023-34235Public exploitNetwork attack vector

Private-field disclosure via prefixed relational filters

Published Jul 25, 2023 · Updated Oct 3, 2024

Information disclosure in Strapi before 4.10.8 allows remote attackers to infer private fields through crafted REST API filters. Query sanitization accepts attacker-supplied Knex table prefixes such as t1 on relational joins, so private-field filtering rules no longer match qualified names. Exploitation requires a publicly readable content type with creator fields enabled or a relation to a type containing private fields, and exposes values through a response oracle.
