Apache WSS4J: Insufficient Validation of Derived-Key Parameters

Published Sep 30, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
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 or 3.0.6 or 2.4.4, which fix this issue.
