{"id":"CVE-2021-32793","details":"Pi-hole's Web interface provides a central location to manage a Pi-hole instance and review performance statistics. Prior to Pi-hole Web interface version 5.5.1, the function to add domains to blocklists or allowlists is vulnerable to a stored cross-site-scripting vulnerability. User input added as a wildcard domain to a blocklist or allowlist is unfiltered in the web interface. Since the payload is stored permanently as a wildcard domain, this is a persistent XSS vulnerability. A remote attacker can therefore attack administrative user accounts through client-side attacks. Pi-hole Web Interface version 5.5.1 contains a patch for this vulnerability.","aliases":["GHSA-g3w6-q4fg-p8x8"],"modified":"2026-08-27T08:13:42.254678Z","published":"2021-08-04T18:15:09.557Z","references":[{"type":"ADVISORY","url":"https://github.com/pi-hole/AdminLTE/releases/tag/v5.5.1"},{"type":"EVIDENCE","url":"https://github.com/pi-hole/AdminLTE/security/advisories/GHSA-g3w6-q4fg-p8x8"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pi-hole/web","events":[{"introduced":"0"},{"fixed":"fb9bd561fdf936891370d85b32e899dff1dbf9d4"}],"database_specific":{"cpe":"cpe:2.3:a:pi-hole:pi-hole:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"5.5.1"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v5.5","v5.4","v5.3.2","v5.3.1","v5.3","v5.2.2","v5.2.1","v5.2","v5.1.1","v5.1","v5.0","v4.3.3","v4.3.2","v4.3","v4.2","v4.1.1","v4.1","v4.0","v3.3","v3.2.1","v3.2","v3.1","v3.0.1a","v3.0.1","v3.0","v2.5.2","v2.5.1","v2.5","v2.4","v2.3.1","v2.3","v2.2","v2.1","v2.0","v1.4.4.2","v1.4.4.1","v1.4.4","v1.4.3.1a","v1.4.3.1","v1.4.3","v1.4.2","v1.4.1","v1.4","v1.3","v1.2","v1.1.7","v1.1.6","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.0","v2.2.0","v2.1.2","2.1.1","2.1.0","v2.1.0-beta","v2.1.0-alpha-1","v2.0.5","v2.0.3","v2.0.2","v2.0.1","v2.0.0","2.0.0","1.2.1","1.2","1.1","1.0","0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-32793.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N"}]}
