CVE-2026-617198.9 ALT—
———WeGIA is a web manager for charitable institutions. Prior to 3.8.7, a stored cross-site scripting vulnerability in `saude/historico_prontuarios.php` arises because the `textoProntuario` field accepts arbitrary HTML or JavaScript without proper sanitization. An attacker able to create or access a patient's medical record can submit the field through `POST /controle/control.php` with `nomeClasse=SaudeControle`, `metodo=alterarProntuario`, and `id_fichamedica`. The stored content is rendered when another user accesses `/html/saude/historico_prontuarios.php` with `id_historico`, automatically executing attacker-controlled JavaScript in the victim's browser. The vulnerability permits session cookie theft and potential account compromise depending on the victim's privileges. This issue is fixed in version 3.8.7.6hCVE-2026-61673——
———WeGIA is a web manager for charitable institutions. Prior to 3.8.7, a stored DOM cross-site scripting vulnerability in `web/html/memorando/listar_despachos.php` results from unsafe handling of the `texto` field. The affected flow spans `web/controle/memorando/DespachoControle.php` and `web/dao/memorando/DespachoDAO.php`: `FILTER_SANITIZE_SPECIAL_CHARS` is applied during storage, but `html_entity_decode()` later decodes the stored content and `jQuery .html()` inserts the result into the DOM. An attacker able to submit a memorandum dispatch through `/controle/control.php` using `DespachoControle` and `metodo=incluir` can store malicious HTML or JavaScript. The code executes automatically when another user views the memorandum thread through `/html/memorando/listar_despachos.php` with `id_memorando`. This permits arbitrary JavaScript execution, theft of administrator `PHPSESSID` session tokens, privileged session hijacking, account takeover, and unauthorized access to privileged or internal functionality. This issue is fixed in version 3.8.7.6hCVE-2026-66912——
———Zimbra is vulnerable to Stored Cross-Site Scripting (XSS) via the From email header during HTML reply composition in Classic UI. Due to insufficient sanitization of the From header value, a remote attacker can send a crafted email containing a malicious From header with an embedded JavaScript payload. When the victim opens the message in Classic UI and clicks Reply while composing in HTML mode with reply headers disabled, the unsanitized From header content is rendered as HTML and the JavaScript payload executes in the victim's browser, potentially allowing the attacker to steal session information or perform actions on behalf of the victim. This issue was fixed in version 10.1.2111hCVE-2026-66911——
———Zimbra is vulnerable to stored cross-site scripting (XSS) via the Content-Location MIME header in email attachments. Due to lack of sanitization of the Content-Location header, an attacker can set it to a javascript: URI. An unauthenticated remote attacker can send a crafted email to a victim; when the victim opens the email in the Zimbra web interface and clicks the attachment name, the JavaScript payload executes in the victim's browser context. This issue was fixed in version 10.1.2111hCVE-2026-619957.1 ALT—
