What is CVE-2026-108523?

A vulnerability exists in the outboundTarget.ts file within the Browse API Endpoint of Sencho, potentially allowing for server-side request forgery through manipulation of the repo_url parameter. This flaw may be exploited remotely, impacting the integrity of repository access.

Nonetheless, as a preventive measure, they have implemented security enhancements to repository access, such as DNS validation, rejection of insecure network types, and maintaining strict verification of SSH host keys. To mitigate this issue, it is essential to apply the provided patch.
