CVE-2025-26614 Overview
CVE-2025-26614 is a SQL injection vulnerability in WeGIA, an open source web manager for institutions targeted at Portuguese language users. The flaw resides in the deletar_documento.php endpoint and allows an authenticated attacker to execute arbitrary SQL queries against the backend database. Successful exploitation exposes sensitive institutional data and can compromise database integrity. The maintainers addressed the issue in WeGIA version 3.2.14. The vulnerability is tracked under CWE-89: SQL Injection.
Critical Impact
An authenticated attacker can extract, modify, or destroy sensitive institutional records by injecting SQL through the deletar_documento.php endpoint.
Affected Products
- WeGIA versions prior to 3.2.14
- Vendor: LabRedesCefetRJ (WeGIA project)
- Component: deletar_documento.php endpoint

Technical Details for CVE-2025-26614
Vulnerability Analysis
The vulnerability is a classic SQL injection in the deletar_documento.php endpoint of the WeGIA web manager. User-controlled input passed to the document deletion handler is concatenated into a SQL statement without parameterization or adequate sanitization. An attacker with valid application credentials can manipulate the request parameters to inject SQL syntax that executes within the application's database context.
Because the endpoint requires authentication, exploitation depends on the attacker having a low-privileged account or compromised session. WeGIA is used by institutions to manage internal records, so the database typically contains personal data, financial entries, and operational information. Injection at this layer breaks all confidentiality, integrity, and availability guarantees of the underlying data store.
Root Cause
The root cause is unsafe construction of SQL queries inside deletar_documento.php. The endpoint accepts request parameters used to identify a document for deletion and concatenates them into a query string without using prepared statements. This pattern matches CWE-89, where data and code share the same channel and untrusted input alters query semantics.
Attack Vector
The attack vector is network-based and requires an authenticated session against the WeGIA application. An attacker submits a crafted HTTP request to the deletar_documento.php endpoint with SQL metacharacters in the vulnerable parameter. The injected payload runs with the database privileges granted to the application user, enabling data exfiltration through UNION-based reads, blind boolean or time-based extraction, and modification or destruction of records.
No public proof-of-concept or exploit code has been published. Refer to the WeGIA GitHub Security Advisory GHSA-3qhx-gfqj-vm2j for the maintainer description of the flaw.
Detection Methods for CVE-2025-26614
Indicators of Compromise
- HTTP requests to deletar_documento.php containing SQL metacharacters such as ', --, UNION, SELECT, SLEEP(, or OR 1=1.
- Unexpected DELETE, UPDATE, or SELECT statements in database query logs originating from the WeGIA application user.
- Spikes in error responses or unusually long response times from the document deletion endpoint, indicating blind or time-based probing.
- Authenticated sessions issuing high volumes of requests to deletar_documento.php from a single source address.
Detection Strategies
- Enable verbose database query logging and alert on syntactically anomalous queries originating from deletar_documento.php.
- Deploy a web application firewall rule set that flags SQL injection patterns on the WeGIA URL path.
- Correlate authentication logs with sudden access to administrative document endpoints by low-privileged accounts.
Monitoring Recommendations
- Forward web server, PHP, and database logs to a central analytics platform and retain them for incident review.
- Establish a baseline of normal request rates and parameter shapes for deletar_documento.php, then alert on deviations.
- Monitor for outbound data transfers from the WeGIA host that exceed expected volumes, which may indicate database extraction.
How to Mitigate CVE-2025-26614
Immediate Actions Required
- Upgrade WeGIA to version 3.2.14 or later on all production and staging instances.
- Rotate database credentials and application session secrets after patching, in case of prior compromise.
- Audit user accounts and revoke any that are no longer required or that show suspicious activity against deletar_documento.php.
- Review database logs for unauthorized SELECT, UPDATE, or DELETE activity since the application was first exposed.
Patch Information
The WeGIA maintainers resolved CVE-2025-26614 in version 3.2.14. The fix is documented in the GitHub Security Advisory GHSA-3qhx-gfqj-vm2j. All earlier releases remain vulnerable and must be upgraded.
Workarounds
- No vendor-supplied workarounds exist; upgrading to 3.2.14 is the only supported remediation.
- As a temporary control, restrict network access to the WeGIA application using IP allowlists or VPN until the upgrade is applied.
- If upgrading is delayed, place a web application firewall in front of WeGIA with strict SQL injection signatures on the deletar_documento.php path.
