CVE-2020-26174 (GCVE-0-2020-26174)

Vulnerability from cvelistv5 – Published: 2020-12-18 09:27 – Updated: 2024-08-04 15:49

Summary

tangro Business Workflow before 1.18.1 requests a list of allowed filetypes from the server and restricts uploads to the filetypes contained in this list. However, this restriction is enforced in the browser (client-side) and can be circumvented. This allows an attacker to upload any file as an attachment to a workitem.

Severity
