Dreeve before 5.8.0 contains a missing authentication vulnerability in StravaWebhookRequestHandler::handleEvent that allows unauthenticated attackers to forge Strava webhook events without signature, verify-token or owner_id checks. Attackers can send forged delete events with a known public Strava activity id to the webhook URL, causing permanent deletion of imported activities and their streams.
