{"id":"CVE-2026-55567","summary":"BleachBit: Exploit File Delete to Escalate Privilege","details":"BleachBit cleans files to free disk space and to maintain privacy. Prior to 6.0.1, privileged Windows cleaning does not lock and validate a target's parent directory before deletion. A local unprivileged user can replace that directory with a Windows junction and use a native symlink to redirect the elevated deletion to an attacker-selected file. The arbitrary privileged file deletion can be combined with Windows Installer behavior to obtain local SYSTEM privileges. This issue is fixed in version 6.0.1.","aliases":["GHSA-vcjw-px28-5w94"],"modified":"2026-09-23T03:47:17.750971574Z","published":"2026-09-21T14:23:42.014Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55567.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-367"]},"references":[{"type":"WEB","url":"https://github.com/bleachbit/bleachbit/releases/tag/v6.0.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55567.json"},{"type":"ADVISORY","url":"https://github.com/bleachbit/bleachbit/security/advisories/GHSA-vcjw-px28-5w94"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55567"},{"type":"FIX","url":"https://github.com/bleachbit/bleachbit/commit/ee128238e92c7192f0c4d6406b1bd0cd9155e7e0"},{"type":"FIX","url":"https://github.com/bleachbit/bleachbit/pull/1774"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bleachbit/bleachbit","events":[{"introduced":"0"},{"fixed":"ee128238e92c7192f0c4d6406b1bd0cd9155e7e0"},{"fixed":"a779b5fc985d7ce72a4880ebdc93a9d68f7f877f"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"6.0.1"}]}}],"versions":["v6.0.0","v4.6.2","v5.1.2","v5.1.1","v5.1.0","v5.0.2","v5.0.1","v5.0.0","v4.9.2","v4.9.1","v4.9.0","v4.6.1","v4.6.0","v4.5.1","v4.5.0","v4.4.2","v4.4.1","v4.4.0","v4.3.0","v4.2.0","v4.1.0","v4.0.0","v3.9.2","v3.9.0","v3.2.0","v3.1.0","v3.0","v2.3","v2.0","v1.19","v1.17","v1.12","v1.10","v1.9.4","v1.9.3","v1.9.2","v1.8","v1.7.7","v1.6","v1.4","v1.3","v1.2","v1.1","v1.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55567.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
