CVE-2024-26144 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. Rails is a web-application framework. Starting with version 5.2.0, there is a possible sensitive session information leak in Active Storage. EPSS estimates a 1.12% chance of exploitation in the next 30 days.

Description

Rails is a web-application framework. Starting with version 5.2.0, 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. The vulnerability is fixed in 7.0.8.1 and 6.1.7.7.
