The best strategy here is 'Mitigate', which means that the company should take actions to reduce the impact or likelihood of the risk. This can include adding additional security controls or seeking alternative solutions to address the identified risk temporarily until the vulnerability can be patched. 'Transfer' would generally imply shifting the risk to another party, such as through insurance, but it would not be a direct action against the vulnerability in the software. 'Accept' would be incorrect because the question states that they do not want to accept the risk as it is. 'Avoid' generally implies ceasing to use the at-risk component altogether, which may not be feasible for operational continuity.
