CVE-2026-104845

A flaw was found in seroval. A remote attacker can cause a Denial of Service DoS by providing crafted JSON input containing an excessively large array length during data deserialization. Due to missing bounds validation when reconstructing array structures, the application synchronously allocates...

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...

EUVD-2026-91744

Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. Prior to 1.6.3, deserializeTypedArray in fromJSON and fromCrossJSON trusts a deserialized source value as an ArrayBuffer and does not bound the serialized element count. An attacker can...

CVE-2026-104845

The Seroval library is vulnerable to a Denial of Service (DoS) condition in versions prior to 1.6.3 . The deserializeTypedArray function within fromJSON and fromCrossJSON fails to bound the serialized element count when trusting a deserialized source value as an ArrayBuffer. An attacker can provi...

CVE-2026-59940

A flaw was found in Seroval, a JavaScript JS value stringification library. The seroval.fromJSON function allows a remote attacker to provide specially crafted JSON Promise control nodes. These nodes can operate on deserialized values without proper verification, leading to unintended server-side...

CVE-2026-59940

In seroval (npm package) versions prior to 1.5.3, fromJSON() suffered a type confusion flaw where attacker-controlled Promise control nodes could operate on values in the general deserialization reference table without verifying they were genuine internal promise resolver records. This caused des...
