Summary

CVE-2023-49090 is a vulnerability affecting CarrierWave, a file upload solution for Ruby web frameworks like Rails and Sinatra. The issue involves a Content-Type allowlist bypass, which may enable XSS attacks. The vulnerability arises from the `allowlisted_content_type?` validation function, which permits Content-Types based on a partial match. Maliciously crafted `content_type` arguments can bypass the intended Content-Type restrictions, leading to unintended permissions. Versions 2.2.5 and 3.0.5 of CarrierWave have been patched to address this vulnerability.
