{"id":"CVE-2026-47425","aliases":["GHSA-q53q-5r4j-5729","PYSEC-2026-2971"],"url":"https://o3.security/vulnerability/CVE-2026-47425","summary":"Rattler vulnerable to entry-point path traversal in noarch:python install (arbitrary file write)","details":"## Summary\n\n`EntryPoint::FromStr` in `rattler_conda_types` performs only `.trim()` on the `command` field before the linker joins it onto the install prefix and writes an executable Python script. A malicious `noarch:python` package can ship an `info/link.json` with an entry-point name containing `..`, `/`, `\\`, or an absolute path; the resulting file is written outside the prefix (or clobbers an existing in-prefix entry-point such as `bin/pip`) with mode `0o775` on Unix and a copied launcher `.exe` on Windows. This affects the default install path of `pixi install`, `rattler-build`, some methods in `py-rattler`, and any other consumer of the `rattler` install crate; no flag or post-link-script opt-in is involved.\n\nResolved in https://github.com/conda/rattler/pull/2445, released in rattler 0.43.2.\n\n## Affected\n\n- Repository: https://github.com/conda/rattler\n- Commit: `a0e61a33da8b9d6de712fab2a879fa9da977e6e3` (HEAD at audit time, 2026-05-13 release)\n- Downstream consumers reached through the same code path: `prefix-dev/pixi` @ `e640477`\n- pixi 0.69.0 and rattler-build 0.65.0 fix this issue\n\n## Researcher\n\nBerkant Koc <me@berkoc.com>\nPGP: 0C588DFD76204987284213EA0AC529C41F8AA5D6","published":"2026-07-21T17:47:40.995Z","modified":"2026-08-12T03:51:10.137967986Z","cvss":null,"epss":{"score":0.00196,"percentile":0.09271,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"rattler","fixedVersion":"0.43.2"},{"ecosystem":"PyPI","name":"py-rattler","fixedVersion":"0.24.0"}],"fix":{"url":"https://github.com/conda/rattler/commit/4f06eca89aa13209774d26dbac077c41b72bac7c","label":"conda/rattler@4f06eca"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47425.json"},{"type":"ADVISORY","url":"https://github.com/conda/rattler/security/advisories/GHSA-q53q-5r4j-5729"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47425"},{"type":"FIX","url":"https://github.com/conda/rattler/commit/4f06eca89aa13209774d26dbac077c41b72bac7c"},{"type":"WEB","url":"https://github.com/conda/rattler/pull/2445"},{"type":"PACKAGE","url":"https://github.com/conda/rattler"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.137967986Z"}}
