GHSA-JP82-F5MQ-HWHP Seroval: Memory exhaustion via unchecked TypedArray length in JSON deserialization

Summary deserializeTypedArray casts the source node to ArrayBuffer without checking it and never bounds the element count. Pass a plain object with a length property and it hits the array-like TypedArray constructor, allocating that many elements. The offset guard above it can't stop this:...

CVE-2026-104846

Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. From 0.12.0 until 1.6.2, fromJSON deserialization of a fulfilled Promise control node can pass a plugin-produced callable-bearing thenable to a native Promise resolver. ECMAScript thenab...

CVE-2026-104846 Seroval: `fromJSON()` Promise thenable assimilation invokes plugin-produced callables (bypass of CVE-2026-59940)

Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. From 0.12.0 until 1.6.2, fromJSON deserialization of a fulfilled Promise control node can pass a plugin-produced callable-bearing thenable to a native Promise resolver. ECMAScript thenab...

CVE-2026-104846

The Seroval library (versions 0.12.0 through 1.6.2 ) is vulnerable to an unexpected code execution flaw during the fromJSON deserialization process. The root cause involves the deserialization of a fulfilled Promise control node, which can pass a plugin-produced callable-bearing thenable to a nat...
