{"id":"CVE-2026-35379","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-35379","generatedAt":"2026-10-28T03:31:02.975Z","title":"This vulnerability leads to unintended data modification or loss when the utility is used in automated scripts or data-cleaning pipelines that rely on standard character class semantics.","description":"A logic error in the tr utility of uutils coreutils causes the program to incorrectly define the [:graph:] and [:print:] character classes. The implementation mistakenly includes the ASCII space character (0x20) in the [:graph:] class and excludes it from the [:print:] class, effectively reversing the standard behavior established by POSIX and GNU coreutils. This vulnerability leads to unintended data modification or loss when the utility is used in automated scripts or data-cleaning pipelines that rely on standard character class semantics. For example, a command executed to delete all graphical characters while intending to preserve whitespace will incorrectly delete all ASCII spaces, potentially resulting in data corruption or logic failures in downstream processing.","published":"2026-04-22T17:16:43.000Z","lastModified":"2026-10-26T22:10:00.000Z","status":"Analyzed","sourceIdentifier":"security@ubuntu.com","cvss":{"version":"3.1","score":3.3,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-684"],"affected":["uutils/coreutils"],"epss":{"score":0.00149,"percentile":0.04046,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.15%).
