CVE-2023-26987Network attack vector

Account manipulation via unchecked POST request

Published May 1, 2023 · Updated Jan 30, 2025

Broken access control in Konga 0.14.9 allows remote authenticated users to manipulate user accounts through a crafted POST request. The public advisory identifies the user-account POST handler as the affected locus but does not disclose the route, fields, or omitted authorization check. Any account privilege suffices; successful exploitation changes account data but has no reported confidentiality or availability impact.
