Prior to version 6.23.0, a lack of validation of the image fingerprint when downloading from simplestreams image servers opens the door to image cache poisoning and under very narrow circumstances exposes other tenants to running attacker controlled images rather than the expected one. Version 6.23.0 patches the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:H/VA:N/SC:L/SI:H/SA:N/E:P","score":5.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","score":4.8},"cwes":["CWE-295"],"references":["https://github.com/lxc/incus/security/advisories/GHSA-p8mm-23gg-jc9r"],"products":["linuxcontainers:incus"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33542","score":0.00183,"percentile":0.07895,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p8mm-23gg-jc9r","url":"https://osv.dev/vulnerability/GHSA-p8mm-23gg-jc9r","summary":"Incus does not verify combined fingerprint when downloading images from simplestreams servers","modified":"2026-04-07T15:26:06.082527627Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus/v6/client","purl":"pkg:golang/github.com/lxc/incus/v6/client","ranges":["<6.23.0"],"fixed":["6.23.0"]}]},{"id":"GO-2026-4882","url":"https://osv.dev/vulnerability/GO-2026-4882","summary":"Incus does not verify combined fingerprint when downloading images from simplestreams servers in github.com/lxc/incus","modified":"2026-04-07T15:15:37.561381Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus","purl":"pkg:golang/github.com/lxc/incus","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/lxc/incus/v6","purl":"pkg:golang/github.com/lxc/incus/v6","ranges":["<6.23.0"],"fixed":["6.23.0"]}]}],"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).
