{"id":"CVE-2026-35379","aliases":["GHSA-fhr3-xh3q-69w6"],"url":"https://o3.security/vulnerability/CVE-2026-35379","summary":"uutils coreutils tr Local Logic Error and Data Integrity Issue in Character Class Handling","details":"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":"2026-04-22T16:09:17.114Z","modified":"2026-08-12T03:51:47.577982586Z","cvss":{"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"},"epss":{"score":0.00149,"percentile":0.04476,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"coreutils","fixedVersion":"0.8.0"}],"fix":{"url":"https://github.com/uutils/coreutils/pull/11405","label":"uutils/coreutils#11405"},"references":[{"type":"WEB","url":"https://github.com/uutils"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35379.json"},{"type":"ADVISORY","url":"https://github.com/uutils/coreutils/releases/tag/0.8.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35379"},{"type":"FIX","url":"https://github.com/uutils/coreutils/pull/11405"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:47.577982586Z"}}
