{"affected":[{"product":"pi-hole","source":"CNA: GitHub_M","vendor":"pi-hole","versions":[{"status":"affected","version":"< 6.5"}]}],"cveId":"CVE-2026-119334","cwes":["CWE-59"],"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.","epss":{"date":"2026-11-02","percentile":0.27842,"score":0.00343},"exploits":[],"kev":null,"metrics":[{"score":2.2,"severity":"low","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1793631573186,"publishedAt":1793390519115,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/pi-hole/pi-hole/security/advisories/GHSA-g63w-24cr-p3w6"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pi-hole/pi-hole/pull/6719"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pi-hole/pi-hole/commit/14554737be53c392abffc69677f6b9df02ae7971"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pi-hole/pi-hole/releases/tag/v6.5"}],"remediation":[],"revision":"b7d13aaf7dd656bc079c74e7c855a177a21b4d763595a3766d83c41d86de8fb1","sources":[{"modifiedAt":1793631573186,"name":"CNA: GitHub_M","retrievedAt":1793632110170,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119334"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793632118579,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-119334"}],"ssvc":{"assessedAt":1793631559239,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Pi-hole: file:// adlist read check and curl can resolve different files","updatedAt":1793632118579}
