CVE-2023-50256Public exploitNetwork attack vector

Incomplete customer records via inconsistent required-field validation

Published Jan 3, 2024 · Updated Jun 17, 2025

Improper input validation in Froxlor before 2.1.2 allows remote attackers to save customer records without a name, surname, or company. The Customers::update path derives company-field requiredness from the stored record instead of the submitted values, while browser validation checks untrimmed string lengths. An unauthenticated crafted submission with omitted or whitespace-only identity fields bypasses both layers and persists an incomplete customer identity record.
