CVE-2026-44587

CarrierWave is a framework to upload files from Ruby applications. In versions prior to 2.2.7 and 3.1.3, the contenttypedenylist check fails to escape regex metacharacters in string entries, causing the denylist to silently not match the content types it is intended to block. In...

CVE-2026-44587

CarrierWave (Ruby) before versions 2.2.7 and 3.1.3 contains a denylisted_content_type bypass: denylist entries are interpolated into a regex without Regexp.quote or a start anchor, so entries like image/svg+xml render the pattern that fails to match the real MIME type (e.g., /image/svg+x/). This ...
