Researcher notes
Public details are limited. The description mixes remote file inclusion terminology with local file inclusion impact. Do not assume a working exploit or a specific patch from the supplied evidence. The strongest facts are affected product/version range, CWE-98 classification, CVSS 8.1 vector, and Patchstack/CVE publication.
