CVE-2025-55037
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 · uneditedImproper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in TkEasyGUI versions prior to v1.0.22. If this vulnerability is exploited, an arbitrary OS command may be executed by a remote unauthenticated attacker if the settings are configured to construct messages from external sources.
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 confidenceTkEasyGUI versions before v1.0.22 contain an OS command injection vulnerability. When the application settings are configured to construct messages from external (untrusted) sources without proper sanitization, an attacker can inject arbitrary OS commands that will be executed on the target system. This is a critical pre-authentication remote code execution vector.

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 checksWork through these to decide whether this CVE applies to you.
-
Check installed TkEasyGUI versionRun 'pip show tkeasygui' or 'pip list | grep -i tkeasygui' to see the installed versionAffected if Version is below 1.0.22 or version cannot be determined (package may be outdated)
-
Identify if application processes external input into messagesSearch source code for patterns where user-supplied data flows into message construction functions - look for string formatting, f-strings, or concatenation involving external input variablesAffected if Application code uses external (untrusted) input to construct messages without sanitization
-
Check for command execution patterns in message handlingSearch codebase for os.system, subprocess calls, or shell=True usage that incorporate message or display-related variables containing external dataAffected if Code executes system commands using message content derived from external input
-
Audit application settings for external data sourcesReview configuration files and application settings to identify if untrusted sources (HTTP parameters, file input, network data) feed directly into GUI message renderingAffected if Settings allow untrusted/external data to drive message content without validation
A user is affected if TkEasyGUI version is below 1.0.22 AND the application uses external input to construct messages displayed by the GUI.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade TkEasyGUI to version 1.0.22 or later. Additionally, audit code paths where external input is used to construct messages and implement proper input validation/sanitization to prevent command injection regardless of library version.
TkEasyGUI v1.0.22
- Check current TkEasyGUI version using: pip show tkeasygui
- Upgrade to version 1.0.22 or later using: pip install --upgrade tkeasygui
- Verify the upgrade was successful by running: pip show tkeasygui and confirming the version is 1.0.22 or higher
