Apache WSS4J remembers the Nonce of each UsernameToken it accepts, so a captured token cannot be reused. It stored the Nonce as raw base64 text, but authentication decodes that text and uses the bytes.The same bytes can be written as base64 in several ways. An attacker who captured an authenticat...

CVE-2026-92899

The Apache WSS4J library is vulnerable to a replay protection bypass because it stores the Nonce of a UsernameToken as raw base64 text. While authentication uses the decoded bytes, an attacker can re-send a captured request with a space added to the base64 Nonce; the password digest remains valid...
