CVE ID :CVE-2026-41689 Published : May 7, 2026, 1:53 p.m. | 1 hour, 12 minutes ago Description :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. Severity: 0.0 | NA Visit the link for more details, such as CVSS details, affected products, timeline, and more...
