Description
This security bulletin contains information about 1 vulnerability.
1) Input validation error (CVE-ID: CVE-2026-81176)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper input validation in devalue.parse when parsing untrusted input. A remote attacker can send a specially crafted payload to cause a denial of service.
The issue occurs because out-of-bounds indices are not properly rejected, which can trigger quadratic work with respect to payload size.
