{"cve":"CVE-2026-47425","nvd":{"published":"2026-07-21T18:17:01.130","modified":"2026-07-23T18:04:31.947","status":"Deferred","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-22","CWE-73"],"references":["https://github.com/conda/rattler/commit/4f06eca89aa13209774d26dbac077c41b72bac7c","https://github.com/conda/rattler/security/advisories/GHSA-q53q-5r4j-5729"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:53.305392138+00:00"},"epss":{"cve":"CVE-2026-47425","score":0.00196,"percentile":0.09315,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-q53q-5r4j-5729","url":"https://osv.dev/vulnerability/GHSA-q53q-5r4j-5729","summary":"rattler has an entry-point path traversal in noarch:python install (arbitrary file write)","modified":"2026-07-13T16:43:29.179358699Z","packages":[{"ecosystem":"crates.io","name":"rattler","purl":"pkg:cargo/rattler","ranges":["<0.43.2"],"fixed":["0.43.2"]},{"ecosystem":"PyPI","name":"py-rattler","purl":"pkg:pypi/py-rattler","ranges":["<0.24.0"],"fixed":["0.24.0"]}]},{"id":"PYSEC-2026-2971","url":"https://osv.dev/vulnerability/PYSEC-2026-2971","summary":"rattler has an entry-point path traversal in noarch:python install (arbitrary file write)","modified":"2026-07-13T16:32:07.504664620Z","packages":[{"ecosystem":"PyPI","name":"py-rattler","purl":"pkg:pypi/py-rattler","ranges":["<0.24.0"],"fixed":["0.24.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
