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
Adobe Campaign Classic (ACC) versions 7.4.3 build 9396 and earlier are affected by an Incorrect Authorization vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.

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

Adobe Campaign Classic versions 7.4.3 build 9396 and earlier contain an Incorrect Authorization vulnerability allowing unauthenticated attackers to execute arbitrary code in the context of the current user. The 'scope changed' designation indicates the vulnerability enables access beyond the intended security boundary of the affected component.

MitigationApply the vendor-supplied patch or upgrade to a newer Adobe Campaign Classic version once available; in the interim, restrict network access to ACC administration interfaces and implement additional authentication layers.

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. Check Adobe Campaign Classic installed version
    Access the Adobe Campaign Client Console, go to Help > About, or check the version.xml/config file in the installation directory to determine the exact version and build number
    Affected if Version is 7.4.3 or earlier with build number 9396 or lower
  2. Verify the web administration interface exposure
    Review network firewall rules and web server configuration to determine if the Adobe Campaign web (port 8080 by default) or JSP containers are accessible from unauthenticated network sources
    Affected if The ACC admin or JSP interfaces are reachable from untrusted networks without authentication
  3. Check for default or weak authentication settings
    Examine the serverConf.xml file in the /conf directory for authentication modes, particularly the 'builtinPS' parameter and sessionToken security settings
    Affected if Authentication is configured to allow anonymous or unauthenticated access to sensitive endpoints
  4. Inspect Tomcat or application server configuration
    Review the Tomcat server.xml or equivalent application server config for exposed servlet mappings that could be reached without credentials
    Affected if Unauthenticated servlet endpoints are exposed in the web container configuration

If Adobe Campaign Classic version is 7.4.3 build 9396 or earlier AND the administration interfaces are network-accessible to unauthenticated users, the environment is vulnerable to CVE-2026-48286.
