{"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":"Rattler is a library that provides common functionality used within the conda ecosystem. Prior to version 0.43.2, `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`, `mamba install` via py-rattler, `rattler-build`, and any other consumer of the `rattler` install crate; no flag or post-link-script opt-in is involved. Version 0.43.2 contains a fix for the issue.","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.137967986Z"}}
