Prior to version 2.4.3, the upload PATCH flow under `/files/:uploadId` validates the mounted request path using the still-encoded `req.path`, but the downstream tus handler later writes using the decoded `req.params.uploadId`. In deployments that use a supported custom `PSITRANSFER_UPLOAD_DIR` whose basename prefixes a startup-loaded JavaScript path, such as `conf`, an unauthenticated attacker can create `config.<NODE_ENV>.js` in the application root. The attacker-controlled file is then executed on the next process restart. Version 2.4.3 contains a patch.","state":0,"publishedAt":"2026-04-23T02:16:15.977+00:00","modifiedAt":"2026-10-25T23:10:00.167+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/psi-4ward/psitransfer/commit/8b547bf3e09757122efa00aab90281e3915aa0c6","https://github.com/psi-4ward/psitransfer/releases/tag/v2.4.3","https://github.com/psi-4ward/psitransfer/security/advisories/GHSA-533q-w4g6-5586"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41180","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-22"],"productCriteria":[],"sourceDates":{"published":"2026-04-23T02:16:15.977","lastModified":"2026-10-25T23:10:00.167"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
