{"cve":"CVE-2026-8594","nvd":{"published":"2026-05-30T16:17:05.067","modified":"2026-07-22T07:10:00.107","status":"Deferred","description":"Text::LineFold versions through 2019.001 for Perl duplicate the output based on the number of special break characters.\n\nText::LineFold splits the input string by specific line break characters (such as VT, FF and others) into segments, but applies the break function to the entire string, not just the segment.\n\nA side effect of this is that the full input can be duplicated for each segment.  Besides being incorrect, this can lead to unexpected resource consumption and possible denial of service.\n\nNote that Text::LineFold is part of the Unicode-LineBreak distribution, which may have a higher version number than the module.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.2},"cwes":["CWE-405","CWE-407"],"references":["https://github.com/hatukanezumi/Unicode-LineBreak/pull/6","https://metacpan.org/release/NEZUMI/Unicode-LineBreak-2019.001/source/lib/Text/LineFold.pm#L407-415","https://security.metacpan.org/patches/U/Unicode-LineBreak/2019.001/CVE-2026-8594-r1.patch","http://www.openwall.com/lists/oss-security/2026/05/30/6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-8594","score":0.00197,"percentile":0.09488,"date":"2026-10-31"},"kev":null,"osv":[],"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).
