7695b0af-958f-11ec-9aa3-4ccc6adda413cryptopp -- ElGamal implementation allows plaintext recovery

Crypto++ 8.6 release notes reports:

The ElGamal implementation in Crypto++ through 8.5 allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP.
