This allows the attacker to \nweaken admission controls and deploy workloads that PSS policies would \notherwise block.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-522"],"references":["https://bugzilla.suse.com/show_bug.cgi?id=CVE-2026-44938","https://github.com/advisories/GHSA-864g-863m-vcvq"],"products":["suse:rancher_fleet"],"source":"nvd","synced_at":"2026-10-25T23:44:34.550481224+00:00"},"epss":{"cve":"CVE-2026-44938","score":0.00442,"percentile":0.38156,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-864g-863m-vcvq","url":"https://osv.dev/vulnerability/GHSA-864g-863m-vcvq","summary":"Fleet has PSS Bypass through addLabelsFromOptions in Fleet Agent","modified":"2026-07-07T16:11:14.187388997Z","packages":[{"ecosystem":"Go","name":"github.com/rancher/fleet","purl":"pkg:golang/github.com/rancher/fleet","ranges":[">=0.15.0 <0.15.2"],"fixed":["0.15.2"]},{"ecosystem":"Go","name":"github.com/rancher/fleet","purl":"pkg:golang/github.com/rancher/fleet","ranges":[">=0.14.0 <0.14.6"],"fixed":["0.14.6"]},{"ecosystem":"Go","name":"github.com/rancher/fleet","purl":"pkg:golang/github.com/rancher/fleet","ranges":[">=0.13.0 <0.13.11"],"fixed":["0.13.11"]},{"ecosystem":"Go","name":"github.com/rancher/fleet","purl":"pkg:golang/github.com/rancher/fleet","ranges":[">=0.12.0 <0.12.15"],"fixed":["0.12.15"]}]},{"id":"GO-2026-5871","url":"https://osv.dev/vulnerability/GO-2026-5871","summary":"Fleet has PSS Bypass through addLabelsFromOptions in Fleet Agent in github.com/rancher/fleet","modified":"2026-07-07T16:00:22.989909990Z","packages":[{"ecosystem":"Go","name":"github.com/rancher/fleet","purl":"pkg:golang/github.com/rancher/fleet","ranges":[">=0.12.0 <0.12.15",">=0.13.0 <0.13.11",">=0.14.0 <0.14.6",">=0.15.0 <0.15.2"],"fixed":["0.12.15","0.13.11","0.14.6","0.15.2"]}]}],"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).
