{"id":"CVE-2026-33368","details":"Zimbra Collaboration Suite (ZCS) 10.0 and 10.1 contains a reflected cross-site scripting (XSS) vulnerability in the Classic Webmail REST interface (/h/rest). The application fails to properly sanitize user-supplied input, allowing an unauthenticated attacker to inject malicious JavaScript into a crafted URL. When a victim user accesses the link, the injected script executes in the context of the Zimbra webmail application, which could allow the attacker to perform actions on behalf of the victim.","modified":"2026-07-15T01:49:11.039689735Z","published":"2026-03-20T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33368.json"},"references":[{"type":"WEB","url":"https://wiki.zimbra.com/wiki/Security_Center"},{"type":"WEB","url":"https://wiki.zimbra.com/wiki/Zimbra_Releases/10.1.16#Security_Fixes"},{"type":"WEB","url":"https://wiki.zimbra.com/wiki/Zimbra_Responsible_Disclosure_Policy"},{"type":"WEB","url":"https://wiki.zimbra.com/wiki/Zimbra_Security_Advisories"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33368.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33368"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zimbra/zm-build","events":[{"introduced":"b68c7b31a1d94f94903a79c53f1bd316b792de1d"},{"fixed":"584cf20b00b29fff46653160e293d0df1f117ec8"}],"database_specific":{"extracted_events":[{"introduced":"10.0.0"},{"fixed":"10.1.16"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:synacor:zimbra_collaboration_suite:*:*:*:*:*:*:*:*"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33368.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/zimbra/zm-zcs-lib","events":[{"introduced":"e94be3228495cb215d7bb70d6ae24bc8a42cc01f"},{"fixed":"450d48208970835622dd1b03d981b8d606d40440"}],"database_specific":{"extracted_events":[{"introduced":"10.0.0"},{"fixed":"10.1.16"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:synacor:zimbra_collaboration_suite:*:*:*:*:*:*:*:*"}}],"versions":["10.1.14","10.1.13","10.1.4","10.1.1","10.1.0","10.0.0-GA"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33368.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
