{"id":"CVE-2026-52875","state":"PUBLISHED","title":"Streambert: Arbitrary Directory Creation and File Manipulation via Backup Handler","description":"Streambert is a cross-platform Electron Desktop App to stream and download video content. Prior to 2.6.0, the perform-scheduled-backup IPC handler in src/ipc/storage.js takes settings.path from a renderer-supplied object and uses the resulting directory for fs.mkdirSync, fs.writeFileSync, fs.readdirSync, and fs.unlinkSync operations without checking that it is inside an authorized backup location. A compromised renderer can choose an absolute path or a relative traversal path to create directories and write a streambert-backup-[timestamp].json file containing renderer-controlled data. The pruning loop can also delete files in that directory whose names begin with streambert-backup- and end with .json. This vulnerability is fixed in 2.6.0.","publishedAt":"2026-08-18T21:30:48.370Z","updatedAt":"2026-08-25T01:44:47.239Z","severity":{"score":8.4,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:L/SI:H/SA:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["truelockmc streambert"],"affected":[{"vendor":"truelockmc","product":"streambert","versions":[{"version":"< 2.6.0","status":"affected"}]}],"references":["https://github.com/truelockmc/streambert/security/advisories/GHSA-c64m-cx97-6rc9","https://github.com/truelockmc/streambert/pull/149","http://github.com/truelockmc/streambert/commit/43566ed031183b046675761c9813c5379b619269"],"weaknesses":["CWE-22","CWE-73"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/52xxx/CVE-2026-52875.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-52875","state":"PUBLISHED","datePublished":"2026-08-18T21:30:48.370Z","dateUpdated":"2026-08-25T01:44:47.239Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-08T21:44:27.364Z"},"containers":{"cna":{"title":"Streambert: Arbitrary Directory Creation and File Manipulation via Backup Handler","descriptions":[{"lang":"en","value":"Streambert is a cross-platform Electron Desktop App to stream and download video content.
