An attacker who can create or update a customer can store a malicious value in the usageAttribution.key or usageAttribution.subjectKeys fields. When that customer is subsequently used in a meter or event query, OpenMeter inserts the stored value into a ClickHouse WITH map(...) expression using string concatenation.
OpenMeter versions from v1.0.0-beta.218 through v1.0.0-beta.231 are affected.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
