MD5 is a weak hash known to have hash collisions.

Dear AppDynamics Security Team,

I am writing to report a security vulnerability identified in our codebase that involves the usage of the MD5 hash function.
The vulnerability associated with the MD5 hash function is that it is susceptible to hash collisions, which occur when two different input values produce the same hash value. This makes it possible for attackers to create malicious data that has the same hash as legitimate data, allowing them to bypass security measures and potentially cause harm.

**Additional Context:** This issue was discovered during an internal security audit, and we wanted to bring it to your attention for review and remediation.

If you require further details or technical support regarding this report, please feel free to reach out.

Thank you,
