Detailsinfo

A vulnerability, which was classified as critical, was found in omnivore-app Omnivore (affected version not known). Affected is the function setWebhookResolver of the file packages/api/src/resolvers/webhooks/index.ts of the component Webhook Resolver. The manipulation of the argument url with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The setWebhookResolver in packages/api/src/resolvers/webhooks/index.ts stores the caller-supplied url without any address validation, and the file imports no validation helper. When a subscribed event fires, callWebhook in packages/api/src/jobs/call_webhook.ts issues axios.request with that url, the method and Content-Type recorded on the webhook, and a JSON body carrying the event data, so an authenticated user can make the server send repeated attacker-shaped requests to internal endpoints, including link-local metadata addresses. The request is blind: callWebhook discards the result and writes only a success line or the axios error to the server log, so the response is not returned through the API.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-77067 since 08/20/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit.

Applying the patch c4d7d8562e6b9aabb1d8e4dabca268e314baa43a is able to eliminate this problem.
