CVE-2026-94676Network attack vector

Object injection via type options and collection ordering

Published Oct 10, 2026 · Updated Oct 10, 2026

PHP object injection in Tainacan 1.3.0 and earlier allows remote authenticated users to inject objects via crafted options. The vendor identifies metadata/filter type options and collection ordering as entry points, but the inspected sources do not disclose the exact deserialization operation. Exploitation requires a privileged custom role; the public advisory does not establish a specific code-execution chain.
