This security bulletin contains information about 1 vulnerability.


1) Interpretation Conflict (CVE-ID: CVE-2026-44974)

CWE-ID: CWE-436 - Interpretation Conflict

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


The vulnerability allows a remote attacker to bypass upload filters.

The vulnerability exists due to interpretation conflict in the @hapi/content header parser when parsing duplicate Content-Disposition or Content-Type parameters. A remote attacker can send a specially crafted request with duplicate header parameters to bypass upload filters.

Exploitation depends on another component in the request-processing chain resolving duplicate parameters differently.
