{"cve":"CVE-2022-39389","nvd":{"published":"2022-11-17T22:15:10.547","modified":"2026-06-17T04:58:16.087","status":"Modified","description":"Lightning Network Daemon (lnd) is an implementation of a lightning bitcoin overlay network node. All lnd nodes before version `v0.15.4` are vulnerable to a block parsing bug that can cause a node to enter a degraded state once encountered. In this degraded state, nodes can continue to make payments and forward HTLCs, and close out channels. Opening channels is prohibited, and also on chain transaction events will be undetected. This can cause loss of funds if a CSV expiry is researched during a breach attempt or a CLTV delta expires forgetting the funds in the HTLC. A patch is available in `lnd` version 0.15.4. Users are advised to upgrade. Users unable to upgrade may use the `lncli updatechanpolicy` RPC call to increase their CLTV value to a very high amount or increase their fee policies. This will prevent nodes from routing through your node, meaning that no pending HTLCs can be present.","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:L/A:L","score":6.5},"cwes":["CWE-20"],"references":["https://github.com/lightningnetwork/lnd/issues/7096","https://github.com/lightningnetwork/lnd/pull/7098","https://github.com/lightningnetwork/lnd/releases/tag/v0.15.4-beta","https://github.com/lightningnetwork/lnd/security/advisories/GHSA-hc82-w9v8-83pr","https://github.com/lightningnetwork/lnd/issues/7096"],"products":["btcd_project:btcd","lightning_network_daemon_project:lightning_network_daemon"],"source":"nvd","synced_at":"2026-10-19T21:37:28.463369388+00:00"},"epss":{"cve":"CVE-2022-39389","score":0.0111,"percentile":0.65937,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hc82-w9v8-83pr","url":"https://osv.dev/vulnerability/GHSA-hc82-w9v8-83pr","summary":"Witness Block Parsing DoS Vulnerability ","modified":"2023-11-08T04:10:20.776131Z","packages":[{"ecosystem":"Go","name":"github.com/lightningnetwork/lnd","purl":"pkg:golang/github.com/lightningnetwork/lnd","ranges":["<0.15.4-beta"],"fixed":["0.15.4-beta"]}]}],"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).
