{"cve":"CVE-2019-16214","nvd":{"published":"2019-09-11T04:15:11.887","modified":"2026-06-17T02:21:54.570","status":"Modified","description":"Libra Core before 2019-09-03 has an erroneous regular expression for inline comments, which makes it easier for attackers to interfere with code auditing by using a nonstandard line-break character for a comment. For example, a Move module author can enter the // sequence (which introduces a single-line comment), followed by very brief comment text, the \\r character, and code that has security-critical functionality. In many popular environments, this code is displayed on a separate line, and thus a reader may infer that the code is executed. However, the code is NOT executed, because language/compiler/ir_to_bytecode/src/parser.rs allows the comment to continue after the \\r character.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N","score":5.7},"cwes":[],"references":["https://blog.openzeppelin.com/libra-vulnerability-release/","https://blog.openzeppelin.com/libra-vulnerability-summary/","https://github.com/libra/libra/commit/7efb0221989f17fdf7f8486730898ed947a1e19e","https://blog.openzeppelin.com/libra-vulnerability-release/","https://blog.openzeppelin.com/libra-vulnerability-summary/"],"products":["libra:libra_core"],"source":"nvd","synced_at":"2026-10-19T20:58:39.700375520+00:00"},"epss":{"cve":"CVE-2019-16214","score":0.01316,"percentile":0.70769,"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).
