What it detects
This rule detects requests to the Sitecore SPEAK bundle endpoint with an absolute path traversal in the f parameter terminated by an encoded fragment, matching the arbitrary file read of web.config described in the Assetnote Sitecore RCE research. Attackers use this primitive to read sensitive configuration and harvest secrets for further exploitation. The combination of the bundle path and traversal markers indicates targeted file disclosure rather than normal asset loading.
