{"id":"CVE-2026-42290","aliases":["GHSA-f84p-cvgm-xgjj"],"url":"https://o3.security/vulnerability/CVE-2026-42290","summary":"protobufjs-cli: OS Command Injection","details":"protobufjs-cli is the command line add-on for protobuf.js. Prior to 1.2.1 and 2.0.2, pbts invoked JSDoc by building a shell command string from input file paths and executing it through child_process.exec. File paths containing shell metacharacters could therefore be interpreted by the shell instead of being passed to JSDoc as plain arguments. This vulnerability is fixed in 1.2.1 and 2.0.2.","published":"2026-05-13T14:49:30.030Z","modified":"2026-07-15T01:49:06.340788339Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":{"score":0.00132,"percentile":0.03168,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"protobufjs-cli","fixedVersion":"1.2.1"},{"ecosystem":"npm","name":"protobufjs-cli","fixedVersion":"2.0.2"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42290.json"},{"type":"ADVISORY","url":"https://github.com/protobufjs/protobuf.js/security/advisories/GHSA-f84p-cvgm-xgjj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42290"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:06.340788339Z"}}
