{"id":"CVE-2026-33989","aliases":["GHSA-3p2m-h2v6-g9mx"],"url":"https://o3.security/vulnerability/CVE-2026-33989","summary":"@mobilenext/mobile-mcp alllows arbitrary file write via Path Traversal in mobile screen capture tools","details":"Mobile Next is an MCP server for mobile development and automation. Prior to version 0.0.49, the `@mobilenext/mobile-mcp` server contains a Path Traversal vulnerability in the `mobile_save_screenshot` and `mobile_start_screen_recording` tools. The `saveTo` and `output` parameters were passed directly to filesystem operations without validation, allowing an attacker to write files outside the intended workspace. Version 0.0.49 fixes the issue.","published":"2026-03-27T22:03:01.801Z","modified":"2026-08-12T03:51:33.941395524Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@mobilenext/mobile-mcp","fixedVersion":"0.0.49"}],"fix":{"url":"https://github.com/mobile-next/mobile-mcp/commit/f5e32295903128c1e71cf915ae6c0b76c7b0153b","label":"mobile-next/mobile-mcp@f5e3229"},"references":[{"type":"WEB","url":"https://github.com/mobile-next/mobile-mcp/releases/tag/0.0.49"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33989.json"},{"type":"ADVISORY","url":"https://github.com/mobile-next/mobile-mcp/security/advisories/GHSA-3p2m-h2v6-g9mx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33989"},{"type":"FIX","url":"https://github.com/mobile-next/mobile-mcp/commit/f5e32295903128c1e71cf915ae6c0b76c7b0153b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:33.941395524Z"}}
