Affected Packages

Package Vulnerable Unaffected -------------- ------------- -------------- dev-ruby/rails < 6.1.6.1:6.1 >= 6.1.6.1:6.1 < 7.0.3.1:7.0 >= 7.0.3.1:7.0

Impact

When serialized columns that use YAML (the default) are deserialized, Rails uses YAML.unsafe_load to convert the YAML data in to Ruby objects. If an attacker can manipulate data in the database (via means like SQL injection), then it may be possible for the attacker to escalate to an RCE.

class User < ApplicationRecord serialize :options # Vulnerable: Uses YAML for serialization serialize :values, Array # Vulnerable: Uses YAML for serialization serialize :values, JSON # Not vulnerable end
The released versions change the default YAML deserializer to use YAML.safe_load, which prevents deserialization of possibly dangerous objects. This may introduce backwards compatibility issues with existing data.

Workaround

There is no known workaround at this time.
