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
Apollo is a reliable configuration management system suitable for microservice configuration management scenarios. Prior to 2.5.0, Apollo Portal does not verify application and namespace permissions when an authenticated user requests a release by ID through GET /envs/{env}/releases/{releaseId} while configView.memberOnly.envs is enabled, allowing a low-privileged Portal user who obtains or guesses a valid releaseId to read configuration data from other applications and namespaces without calling UserPermissionValidator.shouldHideConfigToCurrentUser(...). This issue is fixed in version 2.5.0.

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 · high confidence

Apollo Portal versions prior to 2.5.0 have an IDOR vulnerability where the GET /envs/{env}/releases/{releaseId} endpoint does not perform application and namespace permission checks when configView.memberOnly.envs is enabled. An authenticated low-privileged user who obtains or guesses a valid releaseId can bypass UserPermissionValidator.shouldHideConfigToCurrentUser(...) and read configuration data from other applications and namespaces.

MitigationUpgrade Apollo Portal to version 2.5.0 or later which includes the missing permission validation. Alternatively, if upgrading is not immediately possible, disable the configView.memberOnly.envs configuration or implement compensating controls such as strict access logging on the releases endpoint.

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 Apollo Portal version
    Locate the Apollo Portal version number in the application UI (typically in About or Settings page) or check the build artifact/version file shipped with your installation
    Affected if version is prior to 2.5.0 (any 2.x.x version below 2.5.0)
  2. Locate the Apollo configuration file
    Find the application.properties or application.yml file used by your Apollo Portal deployment - typically in the config directory or classpath
    Affected if the configuration file exists and is accessible for inspection
  3. Check if memberOnly.envs is enabled
    Search for the configuration key 'configView.memberOnly.envs' in the Apollo Portal configuration file and note its value - this setting controls whether certain environments restrict access to members only
    Affected if configView.memberOnly.envs is set to a non-empty value (any environment name) that enables the vulnerable behavior
  4. Verify endpoint accessibility for low-privilege users
    Using a low-privileged user account (non-admin), attempt a GET request to /envs/{env}/releases/{releaseId} using a releaseId from another application or namespace to confirm the IDOR vulnerability exists
    Affected if the request returns configuration data from other applications/namespaces without proper permission denial
  5. Review user role and permissions
    Confirm the test user has limited role permissions (not admin) and is authenticated but lacks application/namespace access rights for the target release
    Affected if the low-privileged authenticated user can access releases outside their authorized applications/namespaces

You are affected if Apollo Portal is version 2.5.0 or earlier, configView.memberOnly.envs is enabled, and a low-privileged authenticated user can read release configurations from applications/namespaces they are not authorized to access.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Apollo Portal to version 2.5.0 or later which includes the missing permission validation. Alternatively, if upgrading is not immediately possible, disable the configView.memberOnly.envs configuration or implement compensating controls such as strict access logging on the releases endpoint.

Recommended fix High confidence

2.5.0

  1. Backup your current Apollo Portal configuration and database
  2. Download Apollo version 2.5.0 from the official releases (github.com/ctripcorp/apollo/releases)
  3. Stop the running Apollo Portal service
  4. Upgrade the Apollo Portal to version 2.5.0 following the standard upgrade documentation
  5. Start the upgraded Apollo Portal service
  6. Verify that the authorization bypass is fixed by testing that low-privileged users cannot access release data via releaseId without proper permissions
