{"cve":"CVE-2026-35368","nvd":{"published":"2026-04-22T17:16:40.560","modified":"2026-10-26T21:10:00.170","status":"Analyzed","description":"A vulnerability exists in the chroot utility of uutils coreutils when using the --userspec option. The utility resolves the user specification via getpwnam() after entering the chroot but before dropping root privileges. On glibc-based systems, this can trigger the Name Service Switch (NSS) to load shared libraries (e.g., libnss_*.so.2) from the new root directory. If the NEWROOT is writable by an attacker, they can inject a malicious NSS module to execute arbitrary code as root, facilitating a full container escape or privilege escalation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":7.8},"cwes":["CWE-426"],"references":["https://github.com/uutils/coreutils/issues/10327","https://github.com/uutils/coreutils/issues/10327"],"products":["uutils:coreutils"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-35368","score":0.00136,"percentile":0.0303,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-mh5c-xrmh-m794","url":"https://osv.dev/vulnerability/GHSA-mh5c-xrmh-m794","summary":"uutils coreutils has an Untrusted Search Path","modified":"2026-09-10T03:51:02.431988164Z","packages":[{"ecosystem":"crates.io","name":"coreutils","purl":"pkg:cargo/coreutils","ranges":["<=0.8.0"],"fixed":[]}]}],"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).
