CVE-2022-29821
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 Rider before 2022.1 local code execution via links in ReSharper Quick Documentation was possible
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 confidenceIn JetBrains Rider before version 2022.1, malicious links embedded in ReSharper Quick Documentation could be crafted to execute arbitrary code locally on the developer's machine, bypassing normal security boundaries.

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.
-
Identify installed JetBrains productCheck system for JetBrains Rider or JetBrains PyCharm installations. Look in common installation directories such as C:\Program Files\JetBrains\ or ~/Library/Application Support/JetBrains/ on macOS, or ~/.config/JetBrains/ on Linux.Affected if Either JetBrains Rider or JetBrains PyCharm is installed on the system
-
Check installed versionLocate the version information for the installed JetBrains product. In Rider, go to Help > About. In PyCharm, go to Help > About. Record the full version number displayed.Affected if The installed version is earlier than 2022.1 (e.g., 2021.3.x, 2021.2.x, etc.)
-
Confirm ReSharper component presenceIn the IDE, navigate to Extensions > ReSharper > Options (or ReSharper > Options). Look for the ReSharper extension status in the IDE. For PyCharm, check if ReSharper Ultimate plugin is installed under Settings > Plugins.Affected if ReSharper component is installed and active in the IDE
-
Check Quick Documentation feature usageIn the IDE, verify if Quick Documentation feature is available. This is typically accessed via Ctrl+Q (Windows/Linux) or F1 (macOS) in Rider, or through ReSharper > IntelliSense > Quick Documentation. Check recent usage history or bookmarks if accessible.Affected if Quick Documentation feature has been used or is available in the IDE
A system is affected if JetBrains Rider or PyCharm with ReSharper is installed with a version earlier than 2022.1 and the Quick Documentation feature has been used or is accessible.
