DescriptionGitHub Advisory

WeGIA is a web manager for charitable institutions. Prior to 3.6.2, a Stored Cross-Site Scripting (XSS) vulnerability was identified in the html/pet/adotantes/cadastro_adotante.php and html/pet/adotantes/informacao_adotantes.php endpoint of the WeGIA application. The application does not sanitize user-controlled input before rendering it inside the Adopters Information table, allowing persistent JavaScript injection. Any user who visits the page will have the payload executed automatically. This vulnerability is fixed in 3.6.2.

AnalysisAI

Public exploit code exists for this vulnerability, which impacts the html/pet/adotantes/cadastro_adotante.php and informacao_adotantes.php endpoints. Organizations should upgrade to version 3.6.2 or later to mitigate the risk of persistent JavaScript injection attacks.
