What this means

Apache TomEE's embedded HTTP server leaks caller identity across requests, allowing a remote unauthenticated attacker to gain privileges of a previously authenticated user. Affected versions include 7.0.0-M1 to 10.0.0-M1 and 10.0.0-M1 to 10.2.0, as well as 11.0.0-M1. Only applications using programmatic or basic authentication are affected.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Public exploit evidence

Original source description

Read the full publisher description

The embedded HTTP server does not clear the security identity established during a request before its worker thread handles the next request. A remote unauthenticated attacker can have their request processed with the identity of a previously authenticated user, gaining that user's privileges. Only applications served by the embedded HTTP server that authenticate programmatically or via basic authentication are 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.
