CVE-2026-12693: Enterprise Video Platform Auth Bypass

CVE-2026-12693 Overview

CVE-2026-12693 is an authorization bypass vulnerability in Vimesoft Inc. Enterprise Video Platform. The flaw is classified under [CWE-639]: Authorization Bypass Through User-Controlled Key. Attackers can access functionality that is not properly constrained by Access Control Lists (ACLs) by manipulating identifiers exposed to the client. The issue affects Enterprise Video Platform versions from 3.11.0.0 before 3.25.0. The vulnerability is exploitable over the network without authentication or user interaction. It carries a CVSS 3.1 base score of 9.4.

Critical Impact
Unauthenticated remote attackers can bypass authorization checks and access restricted functionality, leading to disclosure and modification of sensitive video platform data.

Affected Products

Vimesoft Inc. Enterprise Video Platform 3.11.0.0

Technical Details for CVE-2026-12693

Vulnerability Analysis

The vulnerability resides in the authorization logic of the Enterprise Video Platform. The application relies on user-supplied identifiers, such as object keys or resource references, to determine access to protected functionality. The server trusts these identifiers without independently verifying that the requesting session owns or is entitled to the referenced resource. This pattern matches the Insecure Direct Object Reference class of flaws described in [CWE-639]. Successful exploitation grants attackers access to functionality intended for other users or administrative roles. The scope covers confidentiality of stored video content and metadata, integrity of platform-managed resources, and limited availability impact on affected services.

Root Cause

The root cause is missing or insufficient server-side authorization enforcement on requests keyed by client-controlled parameters. The platform authenticates the session but fails to bind the requested resource identifier to the authorized principal. This design gap allows any authenticated or unauthenticated caller, depending on the endpoint, to substitute another user's identifier and receive a valid response.

Attack Vector

The attack vector is network-based and requires no privileges or user interaction. An attacker sends crafted HTTP requests to the Enterprise Video Platform, substituting resource identifiers such as user IDs, session tokens, media object keys, or ACL references. The server processes the substituted identifier and returns or modifies data belonging to another principal. Refer to the Siber Güvenlik Notification TR-26-0574 for the coordinated advisory details.

Detection Methods for CVE-2026-12693

Indicators of Compromise

HTTP requests to Enterprise Video Platform endpoints containing sequentially enumerated or brute-forced identifier values in URL paths or query parameters.
Access logs showing a single source IP retrieving resources associated with many distinct user or object identifiers within a short window.
Authenticated sessions accessing resources that fall outside the user's normal role or tenant scope.

Detection Strategies

Baseline per-user access to media assets and alert on deviations, especially bulk access to identifiers not previously referenced by the account.
Deploy application-layer monitoring that correlates the authenticated principal with the resource identifier in each request and flags mismatches.
Inspect web server and reverse proxy logs for high-rate requests that iterate through numeric or predictable identifiers.

Monitoring Recommendations

Forward Enterprise Video Platform application logs, web access logs, and identity provider logs to a centralized analytics platform for correlation.
Enable alerting on unusual response sizes and 200-status responses following identifier enumeration patterns.
Track administrative and privileged endpoint access and alert when unauthenticated or low-privilege sessions reach them.

How to Mitigate CVE-2026-12693

Immediate Actions Required

Upgrade Enterprise Video Platform to version 3.25.0 or later on all affected instances.
Inventory internet-exposed Enterprise Video Platform deployments and restrict administrative endpoints to trusted networks until patched.
Rotate credentials, API keys, and session tokens on systems that may have been accessed while the vulnerability was exposed.
Review platform audit logs for prior exploitation attempts consistent with the indicators listed above.

Patch Information

Vimesoft addressed the authorization bypass in Enterprise Video Platform version 3.25.0. Administrators should apply the vendor-supplied update to any deployment running versions between 3.11.0.0 and 3.25.0. Refer to the Siber Güvenlik Notification TR-26-0574 for advisory references and remediation guidance.

Workarounds

Place the Enterprise Video Platform behind an authenticating reverse proxy or web application firewall that enforces per-user resource scoping until the patch is applied.
Restrict network access to the platform to VPN or trusted management subnets.
Disable or block external access to endpoints that expose user or object identifiers in URL parameters where feasible.

bash

# Configuration example: restrict Enterprise Video Platform to trusted subnets at the reverse proxy
location /evp/ {
    allow 10.0.0.0/8;
    deny  all;
    proxy_pass http://evp-backend;
}
