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.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":null}],"references":["https://github.com/open-telemetry/opentelemetry-collector-contrib/security/advisories/GHSA-4jvg-4jfx-fmhc","https://github.com/open-telemetry/opentelemetry-collector-contrib/commit/3113638f216143f523b57f447728464337ae4903","https://github.com/open-telemetry/opentelemetry-collector-contrib/releases/tag/v0.154.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-77692","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 14, 2026, 5:28:15 PM","dateUpdated":"Sep 14, 2026, 6:00:10 PM"},"relatedAdvisories":[{"id":"RHSA-2026:63152","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-47256","CVE-2026-55701"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
