{"id":"CVE-2026-32721","summary":"LuCI luci-mod-network: Possible XSS attack in WiFi scan on Joining Wireless Client modal","details":"LuCI is the OpenWrt Configuration Interface. Versions prior to both 24.10.5 and 25.12.0, contain a stored XSS vulnerability in the wireless scan modal, where SSID values from scan results are rendered as raw HTML without any sanitization. The wireless.js file in the luci-mod-network package passes SSIDs via a template literal to dom.append(), which processes them through innerHTML, allowing an attacker to craft a malicious SSID containing arbitrary HTML/JavaScript. Exploitation requires the user to actively open the wireless scan modal (e.g., to connect to a Wi-Fi access point or survey nearby channels), and only affects OpenWrt versions newer than 23.05/22.03 up to the patched releases (24.10.6 and 25.12.1). The issue has been fixed in version LuCI 26.072.65753~068150b.","aliases":["GHSA-vvj6-7362-pjrw"],"modified":"2026-04-10T05:43:04.077589Z","published":"2026-03-19T22:46:43.909Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32721.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32721.json"},{"type":"ADVISORY","url":"https://github.com/openwrt/luci/security/advisories/GHSA-vvj6-7362-pjrw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32721"},{"type":"FIX","url":"https://github.com/openwrt/luci/commit/068150ba5f524ef6b03817b258d31ec310053fd6"},{"type":"FIX","url":"https://github.com/openwrt/luci/commit/cdce600aaec66f762f18d608c74cbf3abcafe1c7"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openwrt/luci","events":[{"introduced":"0"},{"fixed":"068150ba5f524ef6b03817b258d31ec310053fd6"}]},{"type":"GIT","repo":"https://github.com/openwrt/luci","events":[{"introduced":"0"},{"fixed":"cdce600aaec66f762f18d608c74cbf3abcafe1c7"}]}],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"innerHTML"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32721.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
