CVE-2026-24006: Lxsmnsyc Seroval

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. In versions 1.4.0 and below, serialization of objects with extreme depth can exceed the maximum call stack limit. In version 1.4.1, Seroval introduces a `depthLimit` parameter in serialization/deserialization methods. An error will be thrown if the depth limit is reached.
