DESCRIPTION
There is a possible denial of service vulnerability in the content type parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2024-25126.
Versions Affected: >= 0.4 Not affected: < 0.4 Fixed Versions: 3.0.9.1, 2.2.8.1
Impact
Carefully crafted content type headers can cause Rack’s media type parser to take much longer than expected, leading to a possible denial of service vulnerability.
Impacted code will use Rack’s media type parser to parse content type headers. This code will look like below:
request.media_type
## OR
request.media_type_params
## OR
Rack::MediaType.type(content_type)
Some frameworks (including Rails) call this code internally, so upgrading is recommended!
All users running an affected release should either upgrade or use one of the workarounds immediately.
Releases
The fixed releases are available at the normal locations.
