Rails 3.2.x

3.2.22.50

Bug Fixes

• CVE-2025-24293 (activestorage) allowed transformation methods that were potentially unsafe
• CVE-2025-55193 (activestorage) logging vulnerable to ANSI escape injection

Rack 1.4.7.26

Bug Fixes

• CVE-2025-61919: Rack::Request#POST reads the entire request body into memory for Content-Type:application/x-www-form-urlencoded, calling rack.input.read(nil) without enforcing a length or cap. Large request bodies can therefore be buffered completely into process memory before parsing, leading to denial of service (DoS) through memory exhaustion.
• CVE-2025-61780: A possible information disclosure vulnerability existed in Rack::Sendfile when running behind a proxy that supports x-sendfile headers (such as Nginx). Specially crafted headers could cause Rack::Sendfile to miscommunicate with the proxy and trigger unintended internal requests, potentially bypassing proxy-level access restrictions.

Rack 1.4.7.25

Bug Fixes

• CVE-2025-61770: Rack::Multipart::Parser buffers the entire multipart preamble (bytes before the first boundary) in memory without any size limit. A client can send a large preamble followed by a valid boundary, causing significant memory use and potential process termination due to out-of-memory (OOM) conditions.
• CVE-2025-61771: Rack::Multipart::Parser stores non-file form fields (parts without a filename) entirely in memory as Ruby String objects. A single large text field in a multipart/form-data request (hundreds of megabytes or more) can consume equivalent process memory, potentially leading to out-of-memory (OOM) conditions and denial of service (DoS).
• CVE-2025-61772: Rack::Multipart::Parser can accumulate unbounded data when a multipart part's header block never terminates with the required blank line (CRLFCRLF). The parser keeps appending incoming bytes to memory without a size cap, allowing a remote attacker to exhaust memory and cause a denial of service (DoS).

3.2.22.49

Rack 1.4.7.24

• CVE-2025-49007: There is a denial of service vulnerability in the Content-Disposition parsing component of Rack.
