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
Simple Machines Forum (SMF) 1.1.4 allows remote attackers to read a message in private forums by using the advanced search module with the "show results as messages" option, then searching for possible keywords contained in that message.

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

Simple Machines Forum (SMF) 1.1.4 contains an access control bypass in its advanced search module. When the 'show results as messages' option is used, the search functionality fails to properly enforce permission checks for private forums, allowing unauthorized users to retrieve private message content by searching for keywords contained in those messages.

MitigationApply the vendor patch for SMF 1.1.4 that enforces proper permission validation in the search module, ensuring users cannot access private forum content through search queries.

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. Confirm SMF version is 1.1.4
    Locate the version file or admin panel that displays the installed SMF version. Typical locations include the admin dashboard 'Support' or 'Maintenance' section, or a version.php file in the forum root directory.
    Affected if The installed version is exactly 1.1.4 (no other versions are affected per the advisory)
  2. Verify advanced search module is enabled
    Access the forum as a guest or low-privilege user and navigate to the search feature. Confirm the search function is accessible without administrative credentials.
    Affected if The search module is active and accessible to non-admin users
  3. Check for 'show results as messages' option
    In the search interface, locate the display option that shows results as individual messages rather than a summary list. This is typically a dropdown or radio button setting in the search results view.
    Affected if The 'show results as messages' display option is present and usable
  4. Verify existence of private forums
    Check the forum's category/board structure for boards that have restricted access permissions, or that are designated as private communities accessible only to certain member groups.
    Affected if Private forums (boards with restricted membership or hidden content) exist in the installation
  5. Confirm search indexes private content
    Test whether the search functionality indexes or can retrieve content from private forums when accessed by an unauthorized user account. Attempt a search using keywords likely present in private board posts.
    Affected if Search results can return content from private forums to users who lack permission to view those forums directly

A user is affected if they are running exactly SMF version 1.1.4 and have private forums that could be exposed through the search module's 'show results as messages' option.
