There is no fixed version for org.webjars.bowergithub.kjur:jsrsasign.
Overview
org.webjars.bowergithub.kjur:jsrsasign is a free pure JavaScript cryptographic library.
Affected versions of this package are vulnerable to Observable Discrepancy via the RSA PKCS#1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerability requires the attacker to have access to a large number of ciphertexts encrypted with the same key.
Workaround
The vulnerability can be mitigated by finding and replacing RSA and RSAOAEP decryption with another crypto library.
