Upgrade org.bouncycastle:bcprov-ext-jdk15on to version 1.61 or higher.
Overview
org.bouncycastle:bcprov-ext-jdk15on is a Java implementation of cryptographic algorithms.
Affected versions of this package are vulnerable to Information Exposure. Attackers can obtain sensitive information about a private exponent because of Observable Differences in Behavior to Error Inputs. This occurs in org.bouncycastle.crypto.encodings.OAEPEncoding. Sending invalid ciphertext that decrypts to a short payload in the OAEP Decoder could result in the throwing of an early exception, potentially leaking some information about the private exponent of the RSA private key performing the encryption.
