The CVE-2026-23724 vulnerability affects WeGIA, a web manager designed for charitable institutions. Specifically, prior to version 3.6.2, a Stored Cross-Site Scripting (XSS) vulnerability was identified in the html/atendido/cadastro_ocorrencia.php endpoint of the application. The flaw arises because the application does not adequately sanitize user-controlled data before rendering it within the “Atendido” selection dropdown.
This vulnerability has been assigned a CVSS score of 4.3, which classifies it as medium severity. Organizations utilizing this version of WeGIA are at risk, as attackers may leverage this vulnerability to execute malicious scripts in the context of affected users, potentially leading to further exploitation.
Given the nature of this vulnerability and the potential for misuse, organizations should prioritize patching immediately. The vulnerability was addressed in version 3.6.2, which is crucial for ensuring the security of user interactions with the WeGIA platform.
It is essential for organizations to stay updated with security patches and to regularly assess their systems for vulnerabilities to mitigate risks effectively.
Vulnerability Details
The official CVE description states that WeGIA is a web manager for charitable institutions. The Stored Cross-Site Scripting (XSS) vulnerability allows attackers to inject scripts through the cadastro_ocorrencia.php endpoint. This vulnerability affects all versions prior to 3.6.2.
The vulnerability is classified as CWE-79, indicating a failure to sanitize user input. The CVSS score of 4.3 reflects a medium severity due to its low attack complexity and the requirement for low privileges to exploit it.
Technical Analysis
The root cause of CVE-2026-23724 is the inadequate sanitization of user-controlled data. The attack vector is network-based, allowing remote attackers to exploit this vulnerability without physical access.
Attack complexity is low due to the straightforward nature of the exploit, with attackers requiring only low privileges to execute the attack. User interaction is not required, as the exploitation can happen automatically through malicious inputs.
The impact on confidentiality is low, as the vulnerability does not compromise sensitive data directly but allows script execution. There is no integrity or availability impact associated with this vulnerability.
Risk & Impact Analysis
Organizations using WeGIA prior to version 3.6.2 face a medium risk of exploitation due to the Stored XSS vulnerability. The potential blast radius includes all users interacting with the affected endpoint, which could lead to unauthorized actions through script execution.
Considering the CVSS score of 4.3, the urgency for remediation is categorized as medium. Organizations should schedule remediation as part of their regular security practices to mitigate associated risks.
