While POSIX permits arbitrary bytes in environment strings, the uutils implementation silently skips these entries rather than printing the raw bytes. This vulnerability allows malicious environment variables (e.g., adversarial LD_PRELOAD values) to evade inspection by administrators or security auditing tools, potentially allowing library injection or other environment-based attacks to go undetected.","state":0,"publishedAt":"2026-04-22T17:16:40.167+00:00","modifiedAt":"2026-10-26T22:10:00.163+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security@ubuntu.com · Secondary","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":4.4,"severity":"MEDIUM"}],"references":["https://github.com/uutils/coreutils/issues/9701","https://github.com/uutils/coreutils/pull/9728","https://github.com/uutils/coreutils/releases/tag/0.6.0"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35366","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-754"],"productCriteria":["cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T17:16:40.167","lastModified":"2026-10-26T22:10:00.163"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
