    Title
    IDOR in Comment API Allows Cross-Process Comment Read and Write
    Summary
    The Comment API (GET /api/Comment and POST /api/Comment) in the affected application fails to perform authorization checks to verify that the requesting user has access to the object identified by the relatedObjectId. This Insecure Direct Object Reference (IDOR) vulnerability allows any authenticated user to read and write comments on any process across all business units by supplying an arbitrary object GUID.

    Title
    Server-Side Request Forgery (SSRF) allowing Internal Network Probing in linqi
    Summary
    A Server-Side Request Forgery (SSRF) vulnerability in the custom process creation feature of linqi allows an authenticated attacker to probe internal network components. By crafting a specific process containing an HTTP Request component, an attacker can force the server to send arbitrary HTTP requests. By observing the varying application responses (Success, Failed, or 504 Gateway Time-out), the attacker can determine the status of internal ports, leading to internal network reconnaissance.

    Title
    Improper Authentication Bypass in linqi CDN File Access
    Summary
    An Improper Authentication vulnerability in the /api/Cdn/GetFile endpoint of linqi allows unauthenticated, remote attackers to bypass file access controls. The ValidateAnonFileAccess function incorrectly grants access if an 'AnonFile' query parameter containing exactly 256 characters is provided. While this flaw allows bypassing the intended authorization check, the actual security impact is negligible; the exposed resources are strictly limited to minified JavaScript and CSS files that contain no sensitive data and are already publicly accessible via a standard CDN.

    CVE-2026-11347 (GCVE-0-2026-11347)

    Vulnerability from cvelistv5 – Published: 2026-06-05 10:18 – Updated: 2026-06-05 20:22

    Title
    Hardcoded Cryptographic Keys and Weak IV Generation in linqi
    Summary
    The linqi application contains hardcoded cryptographic keys. Additionally, the application uses a weak algorithm with a limited ASCII charset to dynamically generate Initialization Vectors (IVs) for AES/CBC encryption, making known-plaintext attacks feasible. An attacker with local access can leverage these vulnerabilities to decrypt sensitive obfuscated strings, including ConnectionString values containing database credentials from appsettings.json.
