Vulnerabilidad · Publicado 30/09/2026
Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds. This could permit cryptographically weak keys or excessive CPU and memory consumption when processing crafted WS-Security messages. The fixes enforce a minimum key length of 16 bytes, a maximum length of 512 bytes, and a maximum offset of 4096 bytes.
Users are recommended to upgrade to versions 4.0.2…
