{"id":"CVE-2026-30240","state":"PUBLISHED","title":"Budibase PWA ZIP Upload Path Traversal Allows Reading Arbitrary Server Files Including All Environment Secrets","description":"Budibase is a low code platform for creating internal tools, workflows, and admin panels. In 3.31.5 and earlier, a path traversal vulnerability in the PWA (Progressive Web App) ZIP processing endpoint (POST /api/pwa/process-zip) allows an authenticated user with builder privileges to read arbitrary files from the server filesystem, including /proc/1/environ which contains all environment variables — JWT secrets, database credentials, encryption keys, and API tokens. The server reads attacker-specified files via unsanitized path.join() with user-controlled input from icons.json inside the uploaded ZIP, then uploads the file contents to the object store (MinIO/S3) where they can be retrieved through signed URLs. This results in complete platform compromise as all cryptographic secrets and service credentials are exfiltrated in a single request.","publishedAt":"2026-03-09T20:50:09.129Z","updatedAt":"2026-03-10T15:22:48.070Z","severity":{"score":9.6,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Budibase budibase"],"affected":[{"vendor":"Budibase","product":"budibase","versions":[{"version":"<= 3.31.5","status":"affected"}]}],"references":["https://github.com/Budibase/budibase/security/advisories/GHSA-pqcr-jmfv-c9cp"],"weaknesses":["CWE-22","CWE-73"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/30xxx/CVE-2026-30240.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-30240","state":"PUBLISHED","datePublished":"2026-03-09T20:50:09.129Z","dateUpdated":"2026-03-10T15:22:48.070Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-04T17:23:59.799Z"},"containers":{"cna":{"title":"Budibase PWA ZIP Upload Path Traversal Allows Reading Arbitrary Server Files Including All Environment Secrets","descriptions":[{"lang":"en","value":"Budibase is a low code platform for creating internal tools, workflows, and admin panels.
