Prior to 0.25.5, the /@warpgate/api/sso/providers/:name/start endpoint stores an attacker-controlled next parameter that the POST /@warpgate/api/sso/return handler inserts without HTML escaping into the response generated by warpgate-protocol-http/src/api/sso_provider_list.rs. A victim who follows a crafted link and completes SSO can cause markup and JavaScript to execute in the authenticated Warpgate origin, allowing access to session data and actions through user APIs, and through administrator APIs only when the victim is an administrator. The GET /@warpgate/api/sso/return path also uses the same unvalidated value as a redirect destination, enabling an open redirect. This issue is fixed in version 0.25.5.",null,[11],{"_key":12,"id":12,"name":13,"description":14,"type":15,"status":16,"abstraction":17,"likelihood_of_exploit":18,"capec":19},"CWE-79","Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.","weakness","Stable","Base","High",[20,24,28,32,36,40],{"id":21,"name":22,"techniques":23},"CAPEC-209","XSS Using MIME Type Mismatch",[],{"id":25,"name":26,"techniques":27},"CAPEC-588","DOM-Based XSS",[],{"id":29,"name":30,"techniques":31},"CAPEC-591","Reflected XSS",[],{"id":33,"name":34,"techniques":35},"CAPEC-592","Stored XSS",[],{"id":37,"name":38,"techniques":39},"CAPEC-63","Cross-Site Scripting (XSS)",[],{"id":41,"name":42,"techniques":43},"CAPEC-85","AJAX Footprinting",[],[],[],[],[],[],[],"2026-09-21T18:48:03.982Z","Received",{"cisa_kev":53,"cisa_ransomware":53,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":54,"severity_score":55,"severity_version":56,"severity_source":57,"severity_vector":58,"severity_status":51},false,"critical",9.3,"v3.1","cve.org","CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N",[60,66,71],{"url":61,"sources":62,"tags":64},"https://github.com/warp-tech/warpgate/security/advisories/GHSA-3c3w-75j2-7h74",[57,63],"nvd",[65],"X Refsource CONFIRM",{"url":67,"sources":68,"tags":69},"https://github.com/warp-tech/warpgate/commit/eab0548f018d95b5f96f8e913527000e05ed93a2",[57,63],[70],"X Refsource MISC",{"url":72,"sources":73,"tags":74},"https://github.com/warp-tech/warpgate/releases/tag/v0.25.5",[57,63],[70],[],[],[78,83],{"source":57,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":79,"cvss_v4_0":9},{"baseScore":55,"baseSeverity":80,"vectorString":58,"impactScore":81,"exploitabilityScore":82},"CRITICAL",9.7,7.2,{"source":63,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":84,"cvss_v4_0":9},{"baseScore":55,"baseSeverity":80,"vectorString":58,"impactScore":81,"exploitabilityScore":82},[86],{"ecosystem":9,"name":87,"vendor":88,"product":87,"cpe_part":89,"purl_type":9,"purl_namespace":9,"purl_name":9,"source":9,"versions":90},"warpgate","warp-tech","a",[91],{"version":92,"is_range":93,"range_type":57,"version_start":9,"version_start_type":9,"version_end":94,"version_end_type":95,"fixed_in":9},"\u003C 0.25.5",true,"0.25.5","excluding"]
