CVE-2026-22774
Description
A flaw was found in devalue, a JavaScript library used for serializing values. A remote attacker can exploit this vulnerability by providing specially crafted input to the devalue.parse function. This can cause the application to consume excessive CPU time and memory, leading to a denial of service (DoS) condition. The root cause is an unchecked assumption during typed array hydration, where an ArrayBuffer is expected but not validated.
Statement
This vulnerability is rated Important for Red Hat products that utilize the devalue JavaScript library, such as pgAdmin 4, Red Hat Build of Podman Desktop, and Red Hat Trusted Artifact Signer. A remote attacker can exploit this flaw by providing specially crafted input to the devalue.parse function, leading to excessive CPU and memory consumption and a denial of service condition.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
