{"id":"CVE-2026-33135","summary":"WeGIA has Reflected Cross-Site Scripting (XSS) in `novo_memorandoo.php` via `sccs` parameter","details":"WeGIA is a web manager for charitable institutions. Versions 3.6.6 and below have a Reflected Cross-Site Scripting (XSS) vulnerability in the novo_memorandoo.php endpoint. An attacker can inject arbitrary JavaScript into the sccs GET parameter, which is directly echoed into the HTML response without any sanitization or encoding. The script /html/memorando/novo_memorandoo.php reads HTTP GET parameters to display dynamic success messages to the user. At approximately line 273, the code checks if $_GET['msg'] equals 'success'. If true, it directly concatenates $_GET['sccs'] into an HTML alert \u003cdiv\u003e and outputs it to the browser. This issue has been fixed in version 3.6.7.","aliases":["GHSA-w5rv-5884-w94v"],"modified":"2026-04-10T05:42:36.450489Z","published":"2026-03-20T10:38:44.065Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33135.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-79"]},"references":[{"type":"WEB","url":"https://github.com/LabRedesCefetRJ/WeGIA/releases/tag/3.6.7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33135.json"},{"type":"ADVISORY","url":"https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-w5rv-5884-w94v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33135"},{"type":"FIX","url":"https://github.com/LabRedesCefetRJ/WeGIA/pull/1459"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/labredescefetrj/wegia","events":[{"introduced":"0"},{"fixed":"642c145c6e14d61229b089c9de8a3e11168da78e"}]}],"versions":["0.9.4-beta","3.3.0","3.3.1","3.3.2","3.3.3","3.4.0","3.4.1","3.4.10","3.4.11","3.4.12","3.4.2","3.4.3","3.4.4","3.4.5","3.4.6","3.4.7","3.4.8","3.4.9","3.5.0","3.5.1","3.5.2","3.5.3","3.5.4","3.5.5","3.6.0","3.6.1","3.6.2","3.6.4","3.6.5","3.6.6","v1.0","v2.0","v2.0-beta","v3.1","v3.2.0","v3.2.10","v3.2.11","v3.2.12","v3.2.13","v3.2.14","v3.2.15","v3.2.16","v3.2.17","v3.2.6","v3.2.7","v3.2.8","v3.2.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33135.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:H/I:H/A:N"}]}
