CVE-2026-50139: Patrickhener Goshs

Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days.

goshs is a SimpleHTTPServer written in Go. Prior to version 2.1.0, `ShareHandler` reads the share token's `DownloadLimit` under `RLock`, releases the lock, serves the file, then re-acquires the lock to increment the counter. Concurrent requests all read the same `Downloaded`/`DownloadLimit` snapshot, all pass the check, and all are served — exceeding the operator's intended cap. Version 2.1.0 patches the issue.

Affected products

• Patrickhener Goshs: before 2.1.0 (fixed in 2.1.0)
