This issue specifically occurs when processing encrypted query data received from remote clients and enables an attacker with knowledge of this vulnerability to craft and send specially designed encrypted queries to targeted ODOH servers running with odoh-rs. Upon successful exploitation, the server will crash abruptly, disrupting its normal operation and rendering the service temporarily unavailable.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9},"cwes":["CWE-120"],"references":["https://github.com/cloudflare/odoh-rs/pull/28","https://github.com/cloudflare/odoh-rs/security/advisories/GHSA-gpcv-p28p-fv2p","https://github.com/cloudflare/odoh-rs/pull/28","https://github.com/cloudflare/odoh-rs/security/advisories/GHSA-gpcv-p28p-fv2p"],"products":["cloudflare:odoh-rs"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-3766","score":0.00777,"percentile":0.55832,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gpcv-p28p-fv2p","url":"https://osv.dev/vulnerability/GHSA-gpcv-p28p-fv2p","summary":"odoh-rs's Invalid Slice Split Results in Server Panic","modified":"2026-07-08T06:53:00.615836607Z","packages":[{"ecosystem":"crates.io","name":"odoh-rs","purl":"pkg:cargo/odoh-rs","ranges":["<1.0.2"],"fixed":["1.0.2"]}]},{"id":"RUSTSEC-2023-0095","url":"https://osv.dev/vulnerability/RUSTSEC-2023-0095","summary":"Invalid Slice Split Results in Server Panic","modified":"2026-10-12T18:00:06.118088816Z","packages":[{"ecosystem":"crates.io","name":"odoh-rs","purl":"pkg:cargo/odoh-rs","ranges":[">=0.0.0-0 <1.0.2"],"fixed":["1.0.2"]}]}],"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).
