CVE-2026-23550
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIncorrect Privilege Assignment vulnerability in Modular DS Modular DS modular-connector allows Privilege Escalation.This issue affects Modular DS: from n/a through <= 2.5.1.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA privilege escalation vulnerability exists in the Modular DS modular-connector component due to incorrect privilege assignment. An authenticated or potentially unauthenticated attacker can exploit this flaw to gain elevated access beyond their intended authorization level. The issue affects all versions through 2.5.1, with the fix available in version 2.5.2.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify modular-connector installationLocate the Modular DS modular-connector component in your environment - check for installed packages, services, or applications named 'modular-connector' or 'Modular DS'. Use package managers or system inventory tools to find where this component is deployed.Affected if The modular-connector component is present in the environment and has not been upgraded beyond version 2.5.1.
-
Determine installed versionQuery the installed version of the modular-connector component using the package manager, service information, or version file. Common methods: 'npm list modular-connector', 'pip show modular-connector', or check the application manifest/binary version information.Affected if The installed version is 2.5.1 or earlier (all versions through 2.5.1 are affected).
-
Review user role configuration filesLocate and inspect user role configuration files or databases that define user privileges within the modular-connector. Look for files that assign roles, permissions, or access levels to users.Affected if Incorrect privilege assignment configurations exist that allow unprivileged users to be assigned elevated roles.
-
Audit user accounts and assigned rolesExamine user accounts in the system and verify their assigned roles. Check which users have administrative, elevated, or privileged access versus standard user accounts.Affected if Unprivileged or standard users have been granted elevated access privileges they should not possess.
-
Test for unauthorized access to elevated functionsIf possible, attempt to access higher-privilege functions using a known unprivileged account, or review access logs for successful access to privileged operations by non-admin users.Affected if Unprivileged users can successfully access or execute functions that should require elevated privileges.
The environment is affected if the Modular DS modular-connector version is 2.5.1 or earlier AND unprivileged users have been granted elevated access through incorrect privilege assignment.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Modular DS modular-connector to version 2.5.2 or later. If immediate patching is not possible, restrict network access to the connector component and review access control configurations.
