CVE-2026-49345Public exploitNetwork attack vector

Authenticated internal network access via unvalidated provider URL

Published Jun 19, 2026 · Updated Jun 19, 2026

Server-side request forgery in Sourcentis Mercator before 2025.05.19 allows remote authenticated users to access internal services. ConfigurationController.testProvider passes the provider value directly to curl_init without validating its scheme, host, or destination address. Reachability requires an account with the configure permission; a fragment cancels the appended path, enabling internal scans and requests to exposed Redis or Memcached services.
