Description

This security bulletin contains information about 1 vulnerability.


1) Improper Validation of Specified Quantity in Input (CVE-ID: CVE-2026-82397)

CWE-ID: CWE-1284 - Improper Validation of Specified Quantity in Input

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper validation of the number of fields in application/x-www-form-urlencoded body parsing when processing a crafted form request containing numerous separators. A remote attacker can send a specially crafted form request to cause a denial of service.

The synchronous parsing occurs on the event loop before request dispatch, causing other connections to wait.
