Security readout for executives and security teams
Plain-English summary
CVE-2026-23728 lets a logged-in attacker abuse WeGIA’s trusted domain to send users to external sites. This is mainly a phishing and social-engineering risk, not direct server takeover. The issue affects WeGIA versions before 3.6.2 and is fixed in 3.6.2.
Executive priority
Treat as a normal-priority web application update. The business risk is reputational and credential-theft exposure through phishing, not known system compromise. Prioritize faster if WeGIA is internet-facing or used by vulnerable user groups.
Technical view
WeGIA before 3.6.2 has CWE-601 open redirect in /WeGIA/controle/control.php through the nextPage parameter when used with metodo=listarTodos and nomeClasse=DestinoControle. The application does not sufficiently restrict nextPage, allowing redirects to arbitrary external websites. CVSS v4.0 score is 4.8 with low attack complexity, low privileges, and user interaction required.
Likely exposure
Exposure is limited to organizations running WeGIA versions earlier than 3.6.2, especially deployments reachable by users or the public. The source data does not provide CPEs or deployment-specific indicators, so asset inventory and version checks are required.
Exploitation context
The CVSS vector indicates network access, low privileges, and user interaction are required. The likely abuse is phishing, credential theft, malware delivery, or social engineering using a trusted WeGIA URL. CISA KEV is not indicated, and the provided sources do not report active exploitation.
Researcher notes
Public sources identify the affected endpoint, parameter, class/method combination, CWE, CVSS, and fixed version. They do not provide evidence of exploitation in the wild, CPE mappings, or additional affected products. Avoid assuming impact beyond open redirect abuse.
Mitigation direction
- Upgrade WeGIA to version 3.6.2 or later.
- Review the GitHub advisory and 3.6.2 release notes.
- If upgrade is delayed, check vendor guidance for supported workarounds.
- Monitor for suspicious WeGIA links used in phishing reports.
Validation and detection
- Identify all WeGIA deployments and record installed versions.
- Confirm no production instance runs a version earlier than 3.6.2.
- Review web logs for unusual external redirects involving nextPage.
- Verify patched behavior follows vendor guidance and blocks arbitrary external redirects.

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.
