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
Lack of authorization of the InputManager D-Bus interface in InputPlumber versions before v0.63.0 can lead to local Denial-of-Service, information leak or even privilege escalation in the context of the currently active user session.

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

InputPlumber's InputManager D-Bus interface lacks authorization checks in versions before v0.63.0, allowing any local user to invoke D-Bus methods without proper authentication. This enables local attackers to cause denial-of-service, leak sensitive information, or escalate privileges within the active user session.

MitigationUpgrade InputPlumber to v0.63.0 or later to obtain the authorization checks. Alternatively, restrict D-Bus access through system policy files until the upgrade can be applied.

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 if InputPlumber is installed
    Query your package manager for InputPlumber (e.g., `dpkg -l | grep inputplumber`, `rpm -qa | grep inputplumber`, or check `/usr/bin/inputplumber` existence)
    Affected if InputPlumber is present on the system
  2. Determine installed InputPlumber version
    Run `inputplumber --version` or check via package manager (`dpkg -s inputplumber`, `rpm -qi inputplumber`)
    Affected if Version is earlier than v0.63.0 (e.g., v0.62.x, v0.61.x, etc.)
  3. Verify D-Bus service availability
    Query D-Bus for InputPlumber service: `dbus-send --session --dest=com.inputplumber.InputManager --type=method_call --print-reply /com/inputplumber/InputManager org.freedesktop.DBus.Introspectable.Introspect` or check `busctl list | grep inputplumber`
    Affected if The D-Bus interface is exposed and responds to method calls
  4. Confirm lack of authorization enforcement
    Attempt a non-privileged D-Bus method call from a secondary user account (e.g., `dbus-send --session --dest=com.inputplumber.InputManager --type=method_call /com/inputplumber/InputManager <any_method>`)
    Affected if The call succeeds without authentication or authorization failure

A user is affected if InputPlumber is installed with a version earlier than v0.63.0 AND the D-Bus interface is exposed and callable without authentication.

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

Upgrade InputPlumber to v0.63.0 or later to obtain the authorization checks. Alternatively, restrict D-Bus access through system policy files until the upgrade can be applied.

Recommended fix High confidence

InputPlumber v0.63.0 or later

  1. Check the currently installed version of InputPlumber using your package manager (e.g., `rpm -q inputplumber` or `dpkg -l inputplumber`)
  2. Upgrade InputPlumber to version v0.63.0 or later using your package manager (e.g., `sudo zypper update inputplumber` on openSUSE/SUSE or `sudo apt-get install inputplumber` depending on available packages)
  3. After upgrading, verify the new version is installed correctly
  4. Restart the InputPlumber service or D-Bus session to ensure the patched version is running (e.g., `sudo systemctl restart inputplumber` or log out/in of the session)
