CVE-2026-30961 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. 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. EPSS estimates a 0.25% chance of exploitation in the next 30 days.

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.
