AI-analyzed exploit summary The repository provides a detailed technical analysis of CVE-2026-32699, a Broken Access Control vulnerability in FacturaScripts. It explains how the 'nick' parameter in the EditUser controller can be manipulated via a proxy to rename any account, including the Administrator, leading to audit log corruption.

Description

FacturaScripts is an open source accounting and invoicing software. In versions 2025.92 and earlier, the application fails to validate the nick parameter during a POST request to the EditUser controller. Although the user interface prevents editing this field, a user can bypass this restriction by intercepting the request and modifying the nick form-data parameter to rename any account, including the administrator account. This leads to unauthorized modification of a field intended to be immutable.
