{"id":"CVE-2026-52872","summary":"Streambert: Local File Exfiltration and Overwrite via Subtitle file: Protocol","details":"Streambert is a cross-platform Electron Desktop App to stream and download video content. Prior to 2.5.0, the downloadSubtitleFile utility in src/ipc/downloads.js, reached through the run-download IPC channel, accepts a renderer-supplied subtitle url using the file: URI scheme and passes its decoded pathname to fs.copyFileSync. The renderer also controls downloadPath, which determines the destination path. A compromised renderer can therefore copy any file readable by the StreamBERT process into an attacker-chosen writable location, exposing sensitive local data, and can overwrite existing writable files. This vulnerability is fixed in 2.5.0.","aliases":["GHSA-v74h-2468-rxhh"],"modified":"2026-08-21T03:30:26.110775438Z","published":"2026-08-18T21:26:26.154Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22","CWE-73"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52872.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52872.json"},{"type":"ADVISORY","url":"https://github.com/truelockmc/streambert/security/advisories/GHSA-v74h-2468-rxhh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52872"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/truelockmc/streambert","events":[{"introduced":"0"},{"fixed":"a93c8bd99b8070eb9cfda9140c445bf27ffc4bdc"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.5.0"}],"source":"AFFECTED_FIELD"}}],"versions":["2.4","v.2.3.0","2.3","2.2.1","2.2","2.1","2.0","1.7","1.6","1.5","1.4","1.3","1.2","1.1","1.0","0.3.0","0.2.1","0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-52872.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
