Overview

CVE-2026-41689 is a medium-severity vulnerability. It was published on May 7, 2026 and has a CVSS 3.1 base score of 6.0 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.0, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
