Résumé
Wallos: Shared local webhook allowlist lets low-privilege users send arbitrary requests to allowlisted internal services
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Wallos is an open-source, self-hostable personal subscription tracker. In versions 4.8.4 and prior, the webhook notification feature reuses an administrator-configured local-target allowlist for every logged-in user. Any normal user can fully control a webhook URL, headers, and body, then use Wallos to send server-side requests to allowlisted internal automation services. When such a target exposes deployment or execution APIs, this can further enable adjacent-service RCE, but that downstream result is conditional on the target service. At time of publication, there are no publicly available patches.
