Telemetry disclosure and injection via raw Redis errors
Published Jun 2, 2026 · Updated Jun 2, 2026
Information disclosure in OpenTelemetry eBPF Instrumentation before 0.9.0 allows remote attackers to expose Redis error data in telemetry. In pkg/ebpf/common/redis_detect_transform.go, getRedisError trims a raw Redis error buffer and stores it in request.DBError.Description, which pkg/appolly/app/request/span.go emits unchanged as the span status message. The issue is reached when OBI traces Redis traffic and exports spans; no opt-in is required, so sensitive values enter telemetry backends and attacker-controlled text can contaminate downstream analysis.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
