{"cve":"CVE-2026-48785","nvd":{"published":"2026-09-15T18:17:21.640","modified":"2026-09-25T14:10:13.927","status":"Awaiting Analysis","description":"Apptainer is an open source container platform. Prior to version 1.5.1, Image.AuthorizedPath applies plain string-prefix matching to the limit container paths directive in apptainer.conf, so an allowed path such as /data/safe also authorizes a sibling path such as /data/safe-but-unsafe. A local user can consequently run a container from a directory outside the administrator's intended allowlist when Apptainer operates in setuid mode. Installations that do not use setuid mode or do not configure limit container paths are not affected, and unrestricted user namespaces already allow users to run containers of their choice. This issue is fixed in version 1.5.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L","score":4.8},"cwes":["CWE-22"],"references":["https://github.com/apptainer/apptainer/commit/0ff35257420e0c6cb97dac11d305749c893e5214","https://github.com/apptainer/apptainer/pull/3549","https://github.com/apptainer/apptainer/releases/tag/v1.5.1","https://github.com/apptainer/apptainer/security/advisories/GHSA-cr2j-534f-mf3g"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-48785","score":0.0015,"percentile":0.04151,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cr2j-534f-mf3g","url":"https://osv.dev/vulnerability/GHSA-cr2j-534f-mf3g","summary":"Apptainer has incorrect path matching for 'limit container paths' directive ","modified":"2026-07-07T16:11:14.797679488Z","packages":[{"ecosystem":"Go","name":"github.com/apptainer/apptainer","purl":"pkg:golang/github.com/apptainer/apptainer","ranges":["<1.5.1"],"fixed":["1.5.1"]}]},{"id":"GO-2026-5805","url":"https://osv.dev/vulnerability/GO-2026-5805","summary":"Apptainer has incorrect path matching for 'limit container paths' directive in github.com/apptainer/apptainer","modified":"2026-07-07T16:00:20.664079166Z","packages":[{"ecosystem":"Go","name":"github.com/apptainer/apptainer","purl":"pkg:golang/github.com/apptainer/apptainer","ranges":["<1.5.1"],"fixed":["1.5.1"]}]}],"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).
