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 · unedited
Vulnerability in OpenGrok (component: Web App). Versions that are affected are 1.6.7 and prior. Easily exploitable vulnerability allows low privileged attacker with network access via HTTPS to compromise OpenGrok. Successful attacks of this vulnerability can result in takeover of OpenGrok. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

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 confidence

Vulnerability in OpenGrok web application component allowing a low-privileged authenticated attacker with network access via HTTPS to achieve complete system takeover. The CVSS vector indicates successful attacks impact confidentiality, integrity, and availability at high levels.

MitigationUpgrade OpenGrok to a version newer than 1.6.7. If immediate patching is not possible, restrict network access to the web application and review authentication mechanisms.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed OpenGrok version
    Check the OpenGrok web application version through the management interface, the WAR file metadata, or the application logs. Typically this is visible in the footer of the web interface or in version-related endpoints.
    Affected if The installed version is 1.6.7 or any version lower than 1.6.7.
  2. Confirm the web application is network-accessible
    Verify that the OpenGrok web interface is reachable over HTTPS from network locations beyond localhost. Check firewall rules, reverse proxy configurations, or container/network expose settings.
    Affected if The web application is exposed to network access via HTTPS.
  3. Verify authentication is configured
    Review the authentication configuration for the OpenGrok web application. Check whether the security realm or authentication mechanism is properly enabled in the application server configuration or within OpenGrok settings.
    Affected if Authentication is disabled, misconfigured, or uses weak credentials that could allow a low-privileged attacker to gain access.
  4. Check for existing user accounts
    Inspect the user account configuration to determine if any low-privileged accounts exist in the OpenGrok system. Review the configured users and their assigned roles or permissions.
    Affected if There are authenticated user accounts present in the system, regardless of privilege level.

You are affected if OpenGrok version 1.6.7 or lower is installed, the web interface is network-accessible via HTTPS, and an attacker can obtain any valid authentication credentials.

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 data
Upgrade available Upgrade to a release after 1.6.7
Interim mitigation

Upgrade OpenGrok to a version newer than 1.6.7. If immediate patching is not possible, restrict network access to the web application and review authentication mechanisms.
