{"id":"CVE-2026-119334","published":"2026-10-30T20:17:07.967","lastModified":"2026-10-30T20:17:07.967","description":"Pi-hole is a DNS sinkhole that protects devices from unwanted content without installing any client-side software. Prior to 6.5, gravity.sh checks file:// adlist readability with sudo -u pihole test -r but then allows curl, sometimes running as root, to normalize URL dot segments and open a different file. A pihole-readable decoy can therefore pass the check while curl reads a root-only target, and /proc/self paths can similarly resolve against different processes. Exploitation requires an administrator who can add adlists and can place a symlink and decoy on the filesystem. This issue is fixed in version 6.5.","cvssScore":2.2,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-59"],"vendors":[],"products":[],"references":[{"url":"https://github.com/pi-hole/pi-hole/commit/14554737be53c392abffc69677f6b9df02ae7971","tags":[]},{"url":"https://github.com/pi-hole/pi-hole/pull/6719","tags":[]},{"url":"https://github.com/pi-hole/pi-hole/releases/tag/v6.5","tags":[]},{"url":"https://github.com/pi-hole/pi-hole/security/advisories/GHSA-g63w-24cr-p3w6","tags":[]}],"exploitRefs":[{"url":"https://github.com/pi-hole/pi-hole/commit/14554737be53c392abffc69677f6b9df02ae7971","tags":[]},{"url":"https://github.com/pi-hole/pi-hole/pull/6719","tags":[]},{"url":"https://github.com/pi-hole/pi-hole/releases/tag/v6.5","tags":[]},{"url":"https://github.com/pi-hole/pi-hole/security/advisories/GHSA-g63w-24cr-p3w6","tags":[]}],"hasPoc":true,"ai":null}
