An attacker can generate ephemeral identities (Sybils) and leverage the IPFS connection management reputation system to poison other nodes' routing tables, eclipsing the nodes that are the target of the attack from the rest of the network. Later versions, in particular go-ipfs 0.7, mitigate this.","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:H","score":7.5},"cwes":[],"references":["https://blog.ipfs.io/2020-10-30-dht-hardening/","https://graz.pure.elsevier.com/en/publications/total-eclipse-of-the-heart-disrupting-the-interplanetary-file-sys","https://blog.ipfs.io/2020-10-30-dht-hardening/","https://graz.pure.elsevier.com/en/publications/total-eclipse-of-the-heart-disrupting-the-interplanetary-file-sys"],"products":["protocol:ipfs"],"source":"nvd","synced_at":"2026-10-19T21:11:20.317016139+00:00"},"epss":{"cve":"CVE-2020-10937","score":0.01161,"percentile":0.6716,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r23h-3jmw-q7hr","url":"https://osv.dev/vulnerability/GHSA-r23h-3jmw-q7hr","summary":"Access Restriction Bypass in go-ipfs","modified":"2024-06-04T16:56:49.731127Z","packages":[{"ecosystem":"Go","name":"github.com/ipfs/go-ipfs","purl":"pkg:golang/github.com/ipfs/go-ipfs","ranges":["<0.7.0"],"fixed":["0.7.0"]}]},{"id":"GO-2024-2779","url":"https://osv.dev/vulnerability/GO-2024-2779","summary":"Access Restriction Bypass in go-ipfs in github.com/ipfs/go-ipfs","modified":"2026-03-03T04:55:15.263970Z","packages":[{"ecosystem":"Go","name":"github.com/ipfs/go-ipfs","purl":"pkg:golang/github.com/ipfs/go-ipfs","ranges":["<0.7.0"],"fixed":["0.7.0"]}]}],"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).
