Key points
- The vulnerability affects WeGIA versions prior to 3.8.6 and carries a CVSS score of 8.8.
- An authenticated user with access to the Material & Patrimônio module can exploit the flaw.
- The issue is resolved in version 3.8.6, which restores proper input sanitization.
LabRedesCefetRJ released a fix for WeGIA version 3.8.6 to address a high-severity SQL injection vulnerability identified as CVE-2026-55681. Organizations using earlier versions of this charitable institution management system must upgrade immediately. The flaw allows authenticated users with specific module access to manipulate database queries. This exposure puts institutional records and inventory data at significant risk of unauthorized modification or extraction.
In plain English
The security issue stems from how the application processes user input within the Material & Patrimônio module. When a user submits data to restore a product, the system uses a function called extract($_REQUEST). This action overwrites a value that had previously been sanitized by intval(), leaving the raw input unprotected. The unsanitized data is then inserted directly into UPDATE statements for the produto, isaida, and ientrada tables. This bypass allows an attacker to execute arbitrary SQL commands.
The background
WeGIA is designed as a web manager for charitable institutions, handling sensitive operational data. The vulnerability, classified under CWE-89, represents a classic SQL injection weakness. According to the National Vulnerability Database, the flaw was assigned a CVSS score of 8.8, placing it in the high severity category. The National Vulnerability Database record specifies that the issue exists in all versions prior to 3.8.6. The vendor, LabRedesCefetRJ, addressed the root cause by ensuring input sanitization is not overwritten during the request processing phase.
What changes now
Users of WeGIA must verify their current software version. If the installation is below 3.8.6, the system is vulnerable to exploitation by any authenticated user with access to the relevant module. The vendor has confirmed that version 3.8.6 fixes the issue. Administrators should prioritize upgrading to this specific release to close the security gap. No other workarounds or patches have been mentioned in the available records. Delaying the update leaves the database exposed to potential data breaches.
Who needs to act first
Teams should prioritize systems that are directly accessible to users with access to the inventory or material modules. Before applying the update, it is standard practice to back up the current database and configuration files to prevent data loss during the upgrade process. Verify the fix in a test environment if possible to ensure compatibility with existing customizations. Communicate any scheduled downtime to staff who rely on the Material & Patrimônio module for daily operations. Monitor system logs after the update to confirm that input handling behaves as expected and that no residual vulnerabilities remain in related modules.
Background: SQL injection
SQL injection occurs when user input is treated as code. Attackers insert malicious SQL commands into forms to access, modify, or delete data. You reduce risk by using parameterized queries, validating input, and keeping software updated. This prevents attackers from bypassing authentication or stealing records.

What to do and how to stay safe: WeGIA
- Check the current WeGIA version and upgrade to 3.8.6 if it is lower.
- Restrict access to the Material & Patrimônio module to only those who strictly require it.
- Monitor database logs for unusual UPDATE commands or unexpected data changes.
- Ensure that all user accounts have strong, unique passwords to mitigate authenticated attacks.
