A peer produces such a frame for 4 bytes in `TFramedTransport` (a declared size of zero) or 18 bytes in `THeaderTransport` (a header block that fills the frame), so nothing bounds the depth. The Go stack limit is reached as a `fatal error`, which `recover()` cannot catch, so the whole process dies.\n\n\n\nThis issue affects Apache Thrift: before 0.25.0.\n\n\n\nUsers are recommended to upgrade to version 0.25.0, which fixes the issue.","categories":["Unclassified"],"product":"Apache Thrift","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-83663","source_modified_at":"2026-10-02T17:15:19.858Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache Thrift","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"0","lessThan":"0.25.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-83663","source_modified_at":"2026-10-02T17:15:19.858Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache Thrift","ecosystem":null},"version":"0.25.0","basis":"first unaffected version stated in the CVE record"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00426,"percentile":0.35808,"score_date":"2026-10-23"},"published_at":"2026-10-02T12:18:16.955Z","modified_at":"2026-10-02T17:15:19.858Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-83663","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-02T17:15:19.858Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-83663","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://lists.apache.org/thread/33otcgbqd27wf6qq810q56znzbomnhg1","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://lists.apache.org/thread/yjz317wq7h86q9k8ws6ton0ojgl8hjct","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-02T17:15:08.471242Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-02T17:15:19.858Z","content_hash":"aa4c94da3550adcf5d5f5979fd42aef24981a6dbebed5a73fa8f12febd093ecb"}}
