CVE-2026-30961
An attacker with a public file request link can split an oversized file into chunks each under MaxSize and upload them sequentially, bypassing the size restriction entirely.
Does this matter?
Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.
Description
Gokapi is a self-hosted file sharing server with automatic expiration and encryption support. Prior to 2.2.4, the chunked upload completion path for file requests does not validate the total file size against the per-request MaxSize limit. An attacker with a public file request link can split an oversized file into chunks each under MaxSize and upload them sequentially, bypassing the size restriction entirely. Files up to the server's global MaxFileSizeMB are accepted regardless of the file request's configured limit. This vulnerability is fixed in 2.2.4.
