CVE-2026-30961Network attack vector

Storage exhaustion via unchecked aggregate upload size

Published Mar 13, 2026 · Updated Mar 13, 2026

Improper input validation in Forceu Gokapi before 2.2.4 allows remote authenticated users to exceed file-request upload limits. The chunked-upload completion path checks each chunk against MaxSize but never compares their combined size with the request's configured limit. Anyone holding a shared file-request link can consume storage up to the global MaxFileSizeMB ceiling, potentially interrupting service without exposing data or escalating privileges.
