Application crash via recursive binary token parsing
Published Nov 7, 2024 · Updated Nov 3, 2025
Denial of service in XStream 1.4.20 and earlier allows remote attackers to crash an application through a crafted binary input stream. BinaryStreamReader recursively reads another token after every ID-mapping token, so consecutive mappings trigger unbounded recursion and a StackOverflowError. The application must deserialize attacker-controlled data with BinaryStreamDriver; the resulting failure aborts the executing thread and can interrupt the application.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <1.4.21
- Affected versionversion=< 1.4.21
