{"id":"CVE-2026-49988","aliases":["GHSA-hwpp-h97w-2h3j"],"url":"https://o3.security/vulnerability/CVE-2026-49988","summary":"Repomix: attach_packed_output can bypass file-read secret scanning for supported local files","details":"Repomix is a tool that packs repositories into AI-friendly files. Prior to 1.14.1, the Repomix MCP server attach_packed_output and read_repomix_output flow can register and read arbitrary local .json, .txt, .md, or .xml files without the file_system_read_file runSecretLint() safety check or Repomix packed-output validation, allowing MCP callers to bypass the local file-read secret-scanning boundary. This issue is fixed in version 1.14.1.","published":"2026-07-15T18:05:10.789Z","modified":"2026-08-12T03:51:13.875003416Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"repomix","fixedVersion":"1.14.1"}],"fix":{"url":"https://github.com/yamadashy/repomix/commit/e447f7dba6f51fdb26bcad0c280542fca291960e","label":"yamadashy/repomix@e447f7d"},"references":[{"type":"WEB","url":"https://github.com/yamadashy/repomix/releases/tag/v1.14.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49988.json"},{"type":"ADVISORY","url":"https://github.com/yamadashy/repomix/security/advisories/GHSA-hwpp-h97w-2h3j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49988"},{"type":"FIX","url":"https://github.com/yamadashy/repomix/commit/e447f7dba6f51fdb26bcad0c280542fca291960e"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.875003416Z"}}
