WeGIA, a web manager for charitable institutions, has been found to have a Stored Cross-Site Scripting (XSS) vulnerability prior to version 3.6.2. The vulnerability is located in the endpoints html/pet/adotantes/cadastro_adotante.php and html/pet/adotantes/informacao_adotantes.php. The application fails to sanitize user-controlled input before rendering it in the Adopters Information table, allowing for persistent JavaScript injection. Consequently, any user visiting the page will have the malicious payload executed automatically.
The vulnerability has a CVSS score of 5.3, categorizing it as medium severity. Risk to organizations includes potential data exposure through JavaScript execution, which could lead to unauthorized actions on behalf of users. Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.
As of now, no public exploits have been confirmed. Organizations should remain vigilant and monitor for any signs of exploitation while implementing the recommended patch to version 3.6.2, which resolves this vulnerability.
Given the nature of the vulnerability, it is essential for organizations to validate their defenses against potential exploitation. Regular security assessments can help identify such weaknesses before they are exploited.
Vulnerability Details
This vulnerability allows for the execution of arbitrary JavaScript code on users' browsers due to improper sanitization of user input. The CVSS score of 5.3 indicates a medium severity, with an attack vector classified as network, low attack complexity, and no privileges required for exploitation, making it accessible to a wide range of potential attackers.
The affected product is WeGIA, specifically versions prior to 3.6.2. The vulnerability was published on January 16, 2026, and classified under CWE-79, which pertains to improper neutralization of input during web page generation.
Technical Analysis
The root cause of this vulnerability lies in the WeGIA application’s failure to sanitize user input. This oversight allows attackers to inject malicious JavaScript code into web pages. The attack vector is through network requests to the vulnerable endpoints, with the attack complexity being low, as no special skills are required to exploit this vulnerability.
The exploitation of this vulnerability does not require any privileges, as it can be triggered by any user interacting with the affected pages. User interaction is passive, meaning that merely visiting the page is sufficient for the payload to execute. The impact on confidentiality and integrity is low, while availability is not affected.
Risk & Impact Analysis
Organizations using WeGIA must recognize the potential risks associated with this XSS vulnerability. If exploited, attackers could execute malicious scripts that may lead to data theft, unauthorized actions, or even compromise user accounts. The blast radius is significant, as any user visiting the affected pages may be impacted. Given the CVSS score of 5.3, organizations should address this vulnerability in their priority patch cycle.
The urgency for remediation is underscored by the fact that XSS vulnerabilities can lead to severe outcomes if left unaddressed. Therefore, organizations should schedule remediation as part of their security maintenance practices.

Affected Versions
The vulnerability affects all versions of WeGIA prior to 3.6.2. Organizations should ensure they upgrade to version 3.6.2 or later to mitigate this vulnerability.
Mitigation & Remediation
To mitigate this vulnerability, organizations must patch their WeGIA installations to version 3.6.2. If immediate patching is not feasible, consider implementing input sanitization on user-controlled input fields within the application to prevent JavaScript injection.
Organizations should also conduct regular security assessments and penetration testing to identify and remediate other potential vulnerabilities. For more information on effective testing strategies, organizations can refer to our penetration testing services.
Detection Guidance
Organizations should monitor their logs for unusual activity, particularly related to user interactions with the Adopters Information pages. Look for potential JavaScript injection attempts and anomalous behavior which may indicate exploitation. System changes that align with known exploitation patterns should also be flagged for review.
