Last modified
CVE-2026-86531 is a vulnerability of currently unknown severity. The embedded OpenEJB HTTP server does not limit the size of incoming request bodies or of multipart requests, and does not remove the temporary files it creates for multipart parts. A remote unauthenticated attacker can cause excessive memory or disk usage, leading to denial of service. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
Description
The embedded OpenEJB HTTP server does not limit the size of incoming request bodies or of multipart requests, and does not remove the temporary files it creates for multipart parts. A remote unauthenticated attacker can cause excessive memory or disk usage, leading to denial of service. Deployments using the Tomcat connectors are not affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.
