{"id":"CVE-2026-50130","summary":"Pi-hole: Local privilege escalation from `pihole` user to root via `/etc/pihole/logrotate`","details":"Pi-hole is a DNS sinkhole that protects devices from unwanted content without installing any client-side software. From 6.0 to 6.4.2, a user with code execution as the unprivileged pihole user can escalate to root by replacing /etc/pihole/logrotate. The replacement is laundered to root:root ownership by pihole-FTL-prestart.sh and then parsed as root by the daily pihole flush cron, executing firstaction shell as uid 0. This issue is fixed in version 6.4.3.","aliases":["GHSA-h8w9-qx2v-wrww"],"modified":"2026-07-17T03:41:49.600418322Z","published":"2026-07-14T21:35:00.813Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50130.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-282"]},"references":[{"type":"WEB","url":"https://github.com/pi-hole/pi-hole/releases/tag/v6.4.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50130.json"},{"type":"ADVISORY","url":"https://github.com/pi-hole/pi-hole/security/advisories/GHSA-h8w9-qx2v-wrww"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50130"},{"type":"FIX","url":"https://github.com/pi-hole/pi-hole/commit/18002bf7c6bf382fe5861d01321f427019e1be89"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pi-hole/pi-hole","events":[{"introduced":"0"},{"fixed":"18002bf7c6bf382fe5861d01321f427019e1be89"},{"fixed":"f47b8ede5a8e38f9c703202d324a074dbdba4ca9"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"6.0.0"},{"fixed":"6.4.3"}]}}],"versions":["v6.4.2","v6.4.1","v6.4","v6.3","v6.2.2","v6.2.1","v6.2","v6.1.4","v6.1.3","v6.1.2","v6.1.1","v6.1","v6.0.6","v6.0.5","v6.0.4","v6.0.3","v6.0.1","v6.0","v5.18.4","v5.18.3","v5.18.2","v5.18.1","v5.18","v5.17.3","v5.17.2","v5.17.1","v5.17","v5.16.2","v5.15.4","v5.16.1","v5.16","v5.15.5","v5.14.2","v5.15.3","v5.15.2","v5.15.1","v5.15","v5.14.1","v5.14","v5.13","v5.12.2","v5.12.1","v5.12","v5.11.4","v5.11.3","v5.11.2","v5.11.1","v5.11","v5.10","v5.9.1","v5.9","v5.8.1","v5.8","v5.7","v5.6","v5.5","v5.4","v5.3.1","v5.3","v5.2.4","v5.2.3","v5.2.2","v5.2.1","v5.2","v5.1.2","v5.1.1","v5.1","v5.0","v4.4","v4.3.5","v4.3.4","v4.3.3","v4.3.2","v4.3.1","v4.3","v4.2.2","v4.2.1","v4.2","v4.1.1","v4.1","v4.0","v3.3.1","v3.3","v3.2.1","v3.2","v3.1.4","v3.1","v3.0.1","v3.0","v2.13.2","v2.13.1","v2.13","v2.12.1","v2.12","v2.11.2","v2.11.1","v2.11","v2.10.2","v2.10.1","v2.10","v2.9.5","v2.9.4a","v2.9.4","v2.9.3","V2.9.2","V2.9.1","v2.9","v2.8.1","2.8","v2.7.1","v2.7","v2.6.3","v2.6.2","v2.6.1.2","v2.6.1.1","v2.6.1","v2.6","v2.5.3","v2.5.2","V2.5.1","v2.4","v2.3","v2.2","v2.1","2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50130.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
