Exposure of Sensitive Information to an Unauthorized Actor

CVE-2024-26144

Medium
5.3/10

Summary

Rails is a web-application framework. There is a possible sensitive session information leak in Active Storage. By default, Active Storage sends a 'Set-Cookie' header along with the user's session cookie when serving blobs. It also sets 'Cache-Control' to public. Certain proxies may cache the 'Set-Cookie', leading to an information leak. This issue affects the package activestorage and @rails/activestorage versions 5.2.0.beta1 through 6.1.7.6, and 7.0.0.alpha1 through 7.0.8.
