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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-22","CWE-74"],"references":["https://github.com/open-telemetry/opentelemetry-collector-contrib/commit/3113638f216143f523b57f447728464337ae4903","https://github.com/open-telemetry/opentelemetry-collector-contrib/releases/tag/v0.154.0","https://github.com/open-telemetry/opentelemetry-collector-contrib/security/advisories/GHSA-4jvg-4jfx-fmhc","https://github.com/open-telemetry/opentelemetry-collector-contrib/security/advisories/GHSA-4jvg-4jfx-fmhc"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-47256","score":0.00437,"percentile":0.37969,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-4jvg-4jfx-fmhc","url":"https://osv.dev/vulnerability/GHSA-4jvg-4jfx-fmhc","summary":"opentelemetry-collector-contrib sentryexporter: Path traversal in Sentry exporter via attacker-controlled service.name reaches privileged Sentry API endpoints with operator bearer token","modified":"2026-06-25T18:56:10.457988644Z","packages":[{"ecosystem":"Go","name":"github.com/open-telemetry/opentelemetry-collector-contrib/exporter/sentryexporter","purl":"pkg:golang/github.com/open-telemetry/opentelemetry-collector-contrib/exporter/sentryexporter","ranges":["<0.154.0"],"fixed":["0.154.0"]}]},{"id":"GO-2026-5126","url":"https://osv.dev/vulnerability/GO-2026-5126","summary":"opentelemetry-collector-contrib sentryexporter: Path traversal in Sentry exporter via attacker-controlled service.name reaches privileged Sentry API endpoints with operator bearer token in github.com/open-telemetry/opentelemetry-collector-contrib/exporter/sentryexporter","modified":"2026-06-25T18:45:23.703516791Z","packages":[{"ecosystem":"Go","name":"github.com/open-telemetry/opentelemetry-collector-contrib/exporter/sentryexporter","purl":"pkg:golang/github.com/open-telemetry/opentelemetry-collector-contrib/exporter/sentryexporter","ranges":["<0.154.0"],"fixed":["0.154.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
