CVE-2026-66256

UNSUPPORTED WHEN ASSIGNED Deserialization of Untrusted Data vulnerability in Apache Shindig.

This issue affects Apache Shindig: all versions.

Users with access to the Shindig REST API can send specially-crafted requests to trigger arbitrary code execution on the server.

As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
