ETK-2026-3555Zero's internal tracking ID, independent of the CVE number.
validatingZero is analyzing and reversing it now.description
ArcadeDB deployments using the optional mongodbw plugin can allow unauthenticated reads through legacy MongoDB query handling. A network-reachable MongoDB listener with the plugin enabled is required; an attacker could read documents across server databases without credentials.
Still under analysis: more detail becomes available as the pipeline runs.
mitigation
Upgrade com.arcadedb:arcadedb-mongodbw to version 26.11.1 or later. Until upgraded, disable the MongoDB protocol plugin or restrict access to its listener to trusted networks.
fixed in 26.11.1
outcome
Run in progress: no artifact yet.
