Security readout for executives and security teams
Plain-English summary
WeGIA versions before 3.6.2 contain a reflected cross-site scripting flaw in a memorandum page. An attacker can cause attacker-controlled HTML or JavaScript to run in a user’s browser in the context of WeGIA. This can expose sensitive session data or allow actions as that user. The vendor advisory says version 3.6.2 fixes it.
Executive priority
Treat as urgent for any deployed WeGIA instance, especially internet-facing systems. The flaw can compromise user trust and sensitive workflows through browser-side script execution. Upgrade to 3.6.2 should be prioritized, with access restrictions considered until completion.
Technical view
CVE-2026-23722 affects LabRedesCefetRJ WeGIA before 3.6.2. The html/memorando/insere_despacho.php endpoint reflects the id_memorando GET parameter without proper sanitization or output encoding, classified as CWE-79. The CVSS 3.1 score is 9.1, network exploitable, low complexity, no privileges required, with high confidentiality and integrity impact.
Likely exposure
Organizations running public or internal WeGIA instances below 3.6.2 are potentially exposed. Exposure is highest where untrusted users can reach the affected memorandum endpoint or where staff may interact with attacker-supplied links targeting the WeGIA application.
Exploitation context
The source bundle does not cite active exploitation, and KEV is false. The issue is unauthenticated according to the advisory data, but it is reflected XSS, so practical impact depends on user interaction and browser-session context. No exploit details should be required to assess risk.
Researcher notes
Evidence is limited to the CVE data and GitHub advisory reference. The description identifies the vulnerable file and parameter but does not provide additional environmental constraints. The CVSS vector lists UI:N, which is unusual for reflected XSS; validate actual exploitability against the vendor advisory and application behavior.
Mitigation direction
- Upgrade WeGIA to version 3.6.2 or later.
- Review the GitHub security advisory for any updated vendor guidance.
- Restrict access to WeGIA until upgraded if immediate patching is not possible.
- Prioritize remediation for internet-accessible or broadly reachable deployments.
Validation and detection
- Inventory WeGIA deployments and confirm installed versions.
- Verify all instances are running 3.6.2 or later.
- Check whether html/memorando/insere_despacho.php is reachable from untrusted networks.
- Review web logs for unusual requests to the id_memorando parameter.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
