Nested attributes rejection proc bypass in Active Record There is a vulnerability in how the nested attributes feature in Active Record handles updates in combination with destroy flags when destroying records is disabled. This vulnerability has been assigned the CVE identifier CVE-2015-7577.

Versions Affected: 3.1.0 and newer Not affected: 3.0.x and older Fixed Versions: 5.0.0.beta1.1, 4.2.5.1, 4.1.14.1, 3.2.22.1

Impact

When using the nested attributes feature in Active Record you can prevent the destruction of associated records by passing the allow_destroy: false option to the accepts_nested_attributes_for method. However due to a change in the commit [a9b4b5d][1] the _destroy flag prevents the :reject_if proc from being called because it assumes that the record will be destroyed anyway.

However this isn't true if :allow_destroy is false so this leads to changes that would have been rejected being applied to the record. Attackers could use this do things like set attributes to invalid values and to clear all of the attributes amongst other things. The severity will be dependent on how the

Data Injection Vulnerability in Active Record The create_with functionality in Active Record was implemented incorrectly and completely bypasses the strong parameters protection. Applications which pass user-controlled values to create_with could allow attackers to set arbitrary attributes on models.
