Name of the Vulnerable Software and Affected Versions Rails versions 7.1.0 through 7.1.3.0

Description There is a possible ReDoS vulnerability in the Accept header parsing routines of Action Dispatch. This issue can cause Accept header parsing to take an unexpected amount of time, possibly resulting in a DoS vulnerability. Carefully crafted Accept headers can exploit this issue. Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected.

Recommendations For versions 7.1.0 through 7.1.3.0, upgrade to version 7.1.3.1 or apply the provided patch for the 7.1 series, 7-1-accept-redox.patch. As a temporary workaround, consider restricting access to the Accept header parsing routines in Action Dispatch until a patch is available.
