High (7.5) in apache wss4j. EPSS 5.5% chance of exploitation in the next 30 days. Fixed in org.apache.ws.security:wss4j 1.6.17.
Apache WSS4J before 1.6.17 and 2.0.x before 2.0.2 improperly leaks information about decryption failures when decrypting an encrypted key or message data, which makes it easier for remote attackers to recover the plaintext form of a symmetric key via a series of crafted messages. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-2487.
