Cross-Site Request Forgery (CSRF)

PAC4J is vulnerable to Cross-Site Request Forgery CSRF. The vulnerability is due to weak CSRF token validation relying on hash collisions in String.hashCode, which allows an attacker to forge requests with colliding tokens and perform unauthorized actions without the victim’s consent...

EUVD-2026-23421

PAC4J is vulnerable to Cross-Site Request Forgery CSRF. A malicious attacker can craft a specially designed website which, when visited by a user, will automatically submit a forged cross-site request with a token whose hash collides with the victim's legitimate CSRF token. Importantly, the...

GHSA-VR64-R9QJ-H27F Reading specially crafted serializable objects from an untrusted source may cause an infinite loop and denial of service

Any program on the JVM may read serialized objects via java.io.ObjectInputStream.readObject. Reading serialized objects from an untrusted source is inherently unsafe this affects any program running on any version of the JVM and is a prerequisite for this vulnerability. Clojure classes that...

Amazon Linux 2 : xstream (ALAS-2023-2007)

The version of xstream installed on the remote host is prior to 1.3.1-16. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2007 advisory. XStream serializes Java objects to XML and back again. Versions prior to 1.4.20 may allow a remote attacker to terminate the...
