Service interruption via unbounded recursive traversal
Published Jan 22, 2026 · Updated Jan 22, 2026
Denial of service in lxsmnsyc seroval 1.4.0 and earlier allows remote attackers to interrupt applications via deeply nested objects. Its recursive serialization and deserialization paths traverse nested values without a depth bound, exhausting the JavaScript call stack. Reachability requires a consuming application to pass attacker-controlled values to seroval; the resulting stack exhaustion interrupts that 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.
