Security Bulletin: IBM Security Verify Bridge uses a hard-coded key to encrypt the client secret (CVE-2021-20442)

Summary

The obfuscation logic in IBM Security Verify Bridge (ISVB) relies on a hard-coded key to encrypt the client secret string. This means all ISVB users have the same encryption key. As of v1.0.5, ISVB has re-implemented its obfuscation logic so that each user gets assigned a unique key.
