Prior to version 3.33.4, the plugin file upload endpoint (POST /api/plugin/upload) passes the user-supplied filename directly to createTempFolder() without sanitizing path traversal sequences. An attacker with Global Builder privileges can craft a multipart upload with a filename containing ../ to delete arbitrary directories via rmSync and write arbitrary files via tarball extraction to any filesystem path the Node.js process can access. This issue has been patched in version 3.33.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H","score":8.7},"cwes":["CWE-22"],"references":["https://github.com/Budibase/budibase/commit/6344d06d703660fd05995e61d581593c2349c879","https://github.com/Budibase/budibase/pull/18240","https://github.com/Budibase/budibase/releases/tag/3.33.4","https://github.com/Budibase/budibase/security/advisories/GHSA-2wfh-rcwf-wh23","https://github.com/Budibase/budibase/security/advisories/GHSA-2wfh-rcwf-wh23"],"products":["budibase:budibase"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-35214","score":0.00554,"percentile":0.45965,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-2wfh-rcwf-wh23","url":"https://osv.dev/vulnerability/GHSA-2wfh-rcwf-wh23","summary":"Budibase: Path traversal in plugin file upload enables arbitrary directory deletion and file write","modified":"2026-04-04T06:26:31.876982Z","packages":[{"ecosystem":"npm","name":"@budibase/server","purl":"pkg:npm/%40budibase/server","ranges":["<3.33.4"],"fixed":["3.33.4"]}]}],"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).
