FirebasePerformance is vulnerable to Use after free
36
Low Risk
This Affects:
FirebasePerformanceTL;DR
Affected versions of this package are vulnerable to a Use After Free issue in the didCompleteRequestWithResponse:error: method, where response.MIMEType is accessed from a deallocated NSURLResponse object. This can cause an EXC_BAD_ACCESS crash under certain network or SDK conditions due to premature deallocation and thread-safety issues. The fix ensures the MIME type is safely copied before use to prevent accessing freed memory.

You are affected if you are using a version that falls within the vulnerable range.
