Security readout for executives and security teams
Plain-English summary
WeGIA versions before 3.6.2 can be abused to send users from a trusted WeGIA URL to an attacker-controlled website. This is mainly a phishing and social-engineering risk, not direct server takeover. The vendor reports the issue is fixed in version 3.6.2.
Executive priority
Treat as a near-term remediation item for internet-facing or user-facing WeGIA deployments. It is moderate severity because it supports phishing through a trusted domain, but sources do not show direct system compromise or known active exploitation.
Technical view
CVE-2026-23727 is a CWE-601 open redirect in /WeGIA/controle/control.php involving the nextPage parameter with metodo=listarTodos and nomeClasse=TipoSaidaControle. The parameter is not properly validated or restricted, allowing arbitrary external redirects. CVSS v4.0 score is 4.8 with low attack complexity, low privileges, and user interaction required.
Likely exposure
Organizations running LabRedesCefetRJ WeGIA before 3.6.2 are potentially exposed, especially if the application is reachable by users over a network. Exposure depends on deployed version and whether users can be induced to follow crafted WeGIA links.
Exploitation context
The source bundle does not indicate active exploitation, and CISA KEV is false. Abuse requires user interaction and could support phishing, credential theft, malware delivery, or social engineering by making malicious destinations appear to originate from a trusted WeGIA domain.
Researcher notes
Evidence is limited to the CVE record, GitHub advisory, pull request, and 3.6.2 release. The advisory names the affected endpoint and parameter combination and states the fix version. Avoid assuming broader WeGIA components or exploitation beyond open redirect abuse.
Mitigation direction
- Upgrade WeGIA to version 3.6.2 or later.
- Review the GitHub advisory and release notes before deployment.
- Restrict redirect targets to approved internal paths or trusted domains.
- Monitor for suspicious WeGIA links shared with users.
Validation and detection
- Inventory WeGIA deployments and confirm installed versions.
- Prioritize any instance running below version 3.6.2.
- Review application routing or redirect validation around nextPage.
- Check access logs for unusual control.php redirect patterns.
- Confirm remediation using vendor guidance after upgrade.

Conservative CVE-to-ATT&CK context
These mappings and lookup hints may be relevant to the vulnerability behavior, CWE, affected product, or exposure path. Glexia-inferred context is not an official MITRE, ATT&CK, CWE, or CVE Program mapping.
ATT&CK lookup starting points
Use these exact CWE pages and searches to review the Glexia ATT&CK library from this CVE's weakness and description context.
CWE-601: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCredential and access behavior lookup
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

URL Redirection to Untrusted Site ('Open Redirect')
URL Redirection to Untrusted Site ('Open Redirect') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
