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
The Camera Upload functionality in Plex Media Server through 1.18.2.2029 allows remote authenticated users to write files anywhere the user account running the Plex Media Server has permissions. This allows remote code execution via a variety of methods, such as (on a default Ubuntu installation) creating a .ssh folder in the plex user's home directory via directory traversal, uploading an SSH authorized_keys file there, and logging into the host as the Plex user via SSH.

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

Plex Media Server's Camera Upload feature contains an arbitrary file write vulnerability via directory traversal. Authenticated users can escape the intended upload directory and write files anywhere the Plex service account has filesystem permissions, enabling privilege escalation to code execution by writing SSH authorized_keys or other malicious content to the Plex user's home directory.

MitigationUpgrade Plex Media Server to version 1.18.3 or later. If immediate patching is not feasible, disable the Camera Upload feature, restrict the Plex service account permissions to the minimum required, and consider network isolation of the Plex server.

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 Plex Media Server installation
    Locate the Plex Media Server executable or service. On Windows, check Program Files\Plex\Plex Media Server\PlexMediaServer.exe. On Linux, check /usr/lib/plexmediaserver or /opt/plexmediaserver. On macOS, check /Applications/Plex Media Server.app.
    Affected if Plex Media Server is installed on the system
  2. Determine installed Plex Media Server version
    Open the Plex web interface and navigate to Settings > General, or check the Plex Media Server logs (Plex Media Server.log) for the version string. The version format is like 1.18.2.2029 or later.
    Affected if The installed version number is 1.18.2.2029 or lower (any version <= 1.18.2.2029)
  3. Check if Camera Upload feature is enabled
    In the Plex web interface, go to Settings > Plugins > Camera Upload, or examine the preferences file (Preferences.xml in the Plex data directory) for the setting 'CameraUploadChannelEnable' set to '1'.
    Affected if Camera Upload is enabled (the feature is turned on)
  4. Review Plex service account file permissions
    Examine the filesystem permissions on the Plex data directory and the service account's home directory. Check if the Plex user has write access to sensitive locations such as ~/.ssh/, home directories, or system configuration folders.
    Affected if The Plex service account has write permissions to locations outside the designated upload directory (anywhere beyond the intended Camera Upload folder)

You are affected if Plex Media Server version is 1.18.2.2029 or lower AND the Camera Upload feature is enabled, allowing an authenticated user to escape the upload directory and write files to locations where the Plex service account has permissions.

From vendor data
Upgrade available Upgrade to a release after 1.18.2.2029
Interim mitigation

Upgrade Plex Media Server to version 1.18.3 or later. If immediate patching is not feasible, disable the Camera Upload feature, restrict the Plex service account permissions to the minimum required, and consider network isolation of the Plex server.
