CVE-2026-40682

A flaw was found in Apache OpenNLP. A remote attacker can exploit this vulnerability by providing a specially crafted dictionary file. This can lead to an XML External Entity (XXE) injection, which allows for the disclosure of local files or enables server-side request forgery (SSRF), where the server makes unauthorized requests to other systems.
