CVE-2026-51367 Overview
CVE-2026-51367 affects Bottinelli Informatica Vedo Suite version 1.2.5. The vulnerability allows a remote attacker to obtain sensitive information through the api_vedo/chat endpoint by manipulating the utente_chat parameter. The flaw is an Insecure Direct Object Reference (IDOR), where the application uses user-supplied identifiers to retrieve chat records without verifying that the requester is authorized to access the referenced object.
An attacker who can reach the API endpoint can enumerate or substitute values in the utente_chat parameter to read chat data belonging to other users. This exposes conversation content and any sensitive information processed through the chat interface.
Critical Impact
Unauthorized remote access to chat records and sensitive user data via a single manipulable API parameter.

Technical Details for CVE-2026-51367
Vulnerability Analysis
The issue is an Insecure Direct Object Reference in the Vedo Suite chat API. The api_vedo/chat endpoint accepts the utente_chat parameter, which acts as a direct reference to a chat resource associated with a specific user. The application resolves the parameter to a backing record and returns its contents without enforcing an authorization check that ties the requesting session to ownership of that record.
Because access control is missing at the object level, any authenticated context with API reachability can substitute another user's identifier and receive that user's chat data. This is a classic broken access control pattern where authentication is validated, but authorization to the specific object is not. Sensitive information disclosure follows directly from successful parameter manipulation.
Root Cause
The root cause is missing object-level authorization on the api_vedo/chat endpoint. The application trusts the utente_chat parameter as an authoritative identifier and does not cross-check it against the session principal before returning data.
Attack Vector
The attack vector is remote and network-based. An attacker sends crafted requests to api_vedo/chat with modified utente_chat values to iterate through or target specific user identifiers. No memory corruption or code execution is required; the attack relies entirely on API parameter manipulation. Refer to the Elmec Blog CVE-2026-51367 Analysis for endpoint-level detail.
Detection Methods for CVE-2026-51367
Indicators of Compromise
- Repeated requests to the api_vedo/chat endpoint with sequential or varied utente_chat parameter values from a single source.
- Access patterns where one authenticated session retrieves chat data associated with many distinct user identifiers.
- Unusual outbound data volumes from the Vedo Suite application server following API access spikes.
Detection Strategies
- Instrument web application logs to correlate the utente_chat parameter value against the authenticated session's user identifier and alert on mismatches.
- Baseline normal per-user access counts to api_vedo/chat and flag deviations consistent with enumeration.
- Deploy rules in web application firewalls to detect parameter fuzzing and rapid identifier iteration against the chat endpoint.
Monitoring Recommendations
- Forward Vedo Suite application and web server logs to a centralized analytics platform for query-based hunting.
- Monitor authentication events alongside API access to identify accounts performing cross-tenant reads.
- Alert on HTTP 200 responses to api_vedo/chat requests where the resolved object owner differs from the caller.
How to Mitigate CVE-2026-51367
Immediate Actions Required
- Restrict network exposure of the Vedo Suite api_vedo/chat endpoint to trusted networks or VPN access until a fix is applied.
- Contact Bottinelli Informatica for an updated build addressing the IDOR in version 1.2.5. See the Bottinelli Informatica Vedo Suite product page.
- Audit application logs for prior abuse of the utente_chat parameter and notify affected users if data disclosure is confirmed.
Patch Information
No vendor patch reference is available in the published CVE data at the time of writing. Consult Bottinelli Informatica directly for remediation guidance and updated releases beyond version 1.2.5.
Workarounds
- Enforce object-level authorization at a reverse proxy or API gateway by validating that the utente_chat value matches the authenticated user's session claim.
- Apply rate limiting to the api_vedo/chat endpoint to slow enumeration attempts.
- Temporarily disable the chat API if compensating controls cannot be deployed.
