Prior to 1.62.0, a vulnerability affects the baggage propagation implementation in opentelemetry-api and opentelemetry-extension-trace-propagators. Parsing oversized baggage causes unbounded memory allocation and CPU consumption. Because baggage is automatically re-injected into every outgoing request, the effect can fan out to downstream services that never received the original malicious request. This vulnerability is fixed in 1.62.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-770"],"references":["https://github.com/open-telemetry/opentelemetry-java/commit/03837d3c1763bc35464aea1078671e2ef2336a5f","https://github.com/open-telemetry/opentelemetry-java/pull/8380","https://github.com/open-telemetry/opentelemetry-java/releases/tag/v1.62.0","https://github.com/open-telemetry/opentelemetry-java/security/advisories/GHSA-rcgg-9c38-7xpx","https://access.redhat.com/errata/RHSA-2026:28573"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-45292","score":0.01097,"percentile":0.6561,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rcgg-9c38-7xpx","url":"https://osv.dev/vulnerability/GHSA-rcgg-9c38-7xpx","summary":"OpenTelemetry Java SDK has Unbounded Memory Allocation in W3C Baggage Propagation","modified":"2026-06-09T02:15:07.364273115Z","packages":[{"ecosystem":"Maven","name":"io.opentelemetry:opentelemetry-api","purl":"pkg:maven/io.opentelemetry/opentelemetry-api","ranges":["<1.62.0"],"fixed":["1.62.0"]},{"ecosystem":"Maven","name":"io.opentelemetry:opentelemetry-extension-trace-propagators","purl":"pkg:maven/io.opentelemetry/opentelemetry-extension-trace-propagators","ranges":["<1.62.0"],"fixed":["1.62.0"]}]}],"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).
