CVE-2026-23737 is a high-severity deserialization vulnerability in the lxsmnsyc seroval library versions below 1.4.1. The flaw exists in the fromJSON and fromCrossJSON functions, which improperly handle untrusted input during JSON deserialization, enabling arbitrary JavaScript code execution. Exploitation requires an attacker to perform multiple requests with partial knowledge of serialized data usage, without user interaction but with low privileges. This vulnerability can compromise confidentiality, integrity, and availability of affected systems. Although no known exploits are reported in the wild, the risk is significant due to the potential for remote code execution. The issue is fixed in version 1.4.1.
