Echo: github.com/open-telemetry/opentelemetry-collector-contrib/exporter/sentryexporter: security update to 0.154.0

medium Tenable Self-Hosted Container Security Plugin ID 462460

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-47256)

Solution

Update the github.com/open-telemetry/opentelemetry-collector-contrib/exporter/sentryexporter library and its related packages to version 0.154.0 or later.
