CWE-666: Operation on Resource in Wrong Phase of Lifetime
The product performs an operation on a resource at the wrong phase of the resource's lifecycle, which can lead to unexpected behaviors.
How it's found
Operation on Resource in Wrong Phase of Lifetime describes a general pattern rather than a single fixed bug. Testers use a mix of static analysis and manual code review to find where a target's code matches this pattern, then confirm exploitability by hand.
A resource's lifecycle includes several phases: initialization, use, and release. For each phase, it is important to follow the specifications outlined for how to operate on the resource and to ensure that the resource is in the expected phase. Otherwise, if a resource is in one phase but the operation is not valid for that phase (i.e., an incorrect phase of the resource's lifetime), then this can produce resultant weaknesses. For example, using a resource before it has been fully initialized could cause corruption or incorrect data to be used.

Mitigations
- Architecture and Design: Follow the resource's lifecycle from creation to release.
