CVE-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.
