Upstream source description

MaxSite CMS through 109.6 contains a local file inclusion vulnerability in the ajax and require-maxsite dispatchers that allows unauthenticated attackers to execute privileged handler files by supplying base64-encoded path traversal sequences. Attackers can bypass path validation checks and execute admin-gated handler actions without authentication to access sensitive functionality.
