CVE-2026-85532Apache WSS4J: Insufficient Validation of Derived-Key Parameters

Updated under an hour ago ()

Does this affect you?

It affects Apache Software Foundation Apache WSS4J and 1 other product. Add what you run to find out whether that includes you.

EPSS puts the chance of exploitation in the next 30 days at 0.55%, higher than 44% of scored CVEs.

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.
