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 · uneditedIn JetBrains Junie before 252.549.29 command execution was possible via malicious project file
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 confidenceJetBrains Junie versions prior to 252.549.29 are vulnerable to arbitrary command execution via specially crafted malicious project files, allowing attackers to run commands on the target system.

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.
-
Confirm JetBrains Junie is installedSearch for Junie installation directory: On Windows check 'C:\Program Files\JetBrains\Junie\', on macOS check '/Applications/JetBrains Junie.app' or '~/Library/Application Support/JetBrains/Junie/', on Linux check '~/.local/share/JetBrains/Junie/' or '/opt/JetBrains/Junie/'Affected if Junie is found installed on the system
-
Determine installed Junie versionLocate the version file or launch Junie with --version flag. Common locations: version.txt in the installation directory, or check the application metadata in the app bundleAffected if Cannot determine version or version file is missing
-
Compare version against affected rangeRead the installed version number and compare it to 252.549.29. Any version below 252.549.29 (e.g., 252.549.28, 252.548.x, earlier) is in the affected rangeAffected if Installed version is less than 252.549.29
-
Verify project file handling exposureNote that the vulnerability triggers when opening a malicious project file. No additional configuration check needed - the flaw exists in how Junie processes project files regardless of settingsAffected if Junie version is below 252.549.29 and the user opens project files from untrusted sources
User is affected if JetBrains Junie is installed with any version below 252.549.29 and they handle project files from potentially untrusted sources
