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
Bypass to the fix for CVE-2026-34916. Variants of such vectors have been also reported by phucrio and offsetmd. The fix can be bypassed either by sending a disallowed but otherwise valid plugin identifier as `type`, or using the `ox.setChannelTargeting` XML-RPC API method.

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

This is an authentication/authorization bypass vulnerability in what appears to be an ad server or similar platform (likely OpenX). Attackers can bypass the fix for CVE-2026-34916 by either submitting a disallowed but valid plugin identifier as the 'type' parameter, or by exploiting the ox.setChannelTargeting XML-RPC API method. This allows unauthorized access or actions that should have been prevented by the original fix.

MitigationImplement stricter input validation that rejects any plugin identifiers not explicitly whitelisted, and add proper authorization checks to the ox.setChannelTargeting XML-RPC API method. Consider disabling or restricting XML-RPC functionality if not required.

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 Revive Adserver installation and version
    Locate the Revive Adserver installation directory and check the version file (typically version.php or similar) to determine the installed version number
    Affected if The installed version is Revive Adserver and the version is less than 6.0.8
  2. Confirm XML-RPC interface is accessible
    Check if XML-RPC functionality is enabled by examining the server configuration or attempting to access the XML-RPC endpoint (commonly at /www/delivery/rpc.php or similar)
    Affected if XML-RPC interface is exposed and accessible without additional authorization controls
  3. Inspect plugin type parameter handling
    Review the application code that processes the 'type' parameter in plugin-related requests to verify whether it properly validates against an explicit whitelist
    Affected if The code accepts plugin identifiers for the 'type' parameter without strict whitelisting validation
  4. Verify ox.setChannelTargeting API authorization
    Examine the implementation of the ox.setChannelTargeting XML-RPC method to determine if proper authorization checks are performed before executing the method
    Affected if The ox.setChannelTargeting method can be invoked without sufficient authorization validation

A user is affected if they are running Revive Adserver version lower than 6.0.8 with XML-RPC enabled and the plugin type parameter lacks strict whitelist validation or the ox.setChannelTargeting method lacks proper authorization checks.

Upgrade available Upgrade to 6.0.8 or later
Fixed in 6.0.8
Interim mitigation

Implement stricter input validation that rejects any plugin identifiers not explicitly whitelisted, and add proper authorization checks to the ox.setChannelTargeting XML-RPC API method. Consider disabling or restricting XML-RPC functionality if not required.

Recommended fix Moderate confidence

Revive Adserver 6.0.8

  1. Confirm current Revive Adserver version by checking the admin interface or configuration files
  2. Back up the existing Revive Adserver database and files
  3. Download Revive Adserver version 6.0.8 from the official repository or website
  4. Extract the new version files to the server
  5. Run any provided upgrade scripts or migration tools included in the 6.0.8 release
  6. Verify the upgrade was successful by checking the admin interface reports the new version
  7. Test that the ox.setChannelTargeting XML-RPC API method is properly restricted or patched
  8. Validate that disallowed plugin identifiers are properly blocked
Caveat Review the 6.0.8 release notes for any breaking changes or database migrations before upgrading
