Impact

FastTube version 1.0.1.0 contains a denial‑of‑service vulnerability that can be triggered when a user submits a search query longer than 1900 characters. The excessive string causes the application to crash, rendering it unavailable to the user initiating the request.

Affected Systems

The affected product is FastTube, version 1.0.1.0, as listed by the vendor. No other products or versions are noted.

Risk and Exploitability

The CVSS v3.1 score of 6.9 indicates a moderate‑to‑high impact. Exploitation requires local access to a device running the application, limiting the attack surface. EPSS data is not available, and the flaw is not currently listed in the CISA KEV catalog, but the moderate severity recommends that users patch promptly when an update is released.
