NVD Description

OpenTelemetry, also known as OTel, is a vendor-neutral open source Observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, and logs. Prior to 0.154.0, the Sentry exporter reads the remote OTLP sender-controlled service.name resource attribute in exporter/sentryexporter/sentry_exporter.go through extractProjectSlug and getOrCreateProjectEndpoint, passes the raw project slug to GetOTLPEndpoints and GetProjectKeys in exporter/sentryexporter/sentry_client.go, and interpolates it into a Sentry API URL without applying projectSlugRegexp through validateRoutingConfig at runtime in exporter/sentryexporter/config.go. Special characters can turn the expected path suffix into query data in all deployments or introduce slash and dot segments that traverse paths when the Sentry deployment normalizes them, while the Collector attaches its operator-configured bearer token to the request. A successful request can reach token-authorized administrative, organization, member, or key endpoints within the configured Sentry organization, and an attacker-controlled project slug can redirect subsequently exported telemetry. Sentry token middleware prevents cross-organization access. This issue is fixed in version 0.154.0.
