CVE-2025-43016
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 2025.1.2 custom archive unpacker allowed arbitrary file overwrite during remote debug 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 confidenceJetBrains Rider before version 2025.1.2 contains a path traversal vulnerability in its custom archive unpacker. During remote debug sessions, an attacker can craft a malicious archive that extracts files to arbitrary locations on the filesystem, enabling arbitrary file overwrite outside the intended project directory.

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 JetBrains Rider versionOpen JetBrains Rider and navigate to Help > About (or use the command line: rider64.exe version). Alternatively, check the installation directory for version metadata.Affected if The displayed version is earlier than 2025.1.2 (e.g., 2025.1, 2024.x, or any version number less than 2025.1.2).
-
Confirm remote debug configurationExamine your Run/Debug configurations in Rider. Look for any configurations using 'Remote Debug' mode, or check project settings for remote debug attachments.Affected if Remote debug sessions are actively configured or frequently used in your workflow.
-
Check for custom archive extraction usageReview your project for any custom archive extraction operations, particularly during build or deployment processes that may use Rider's unpacker functionality.Affected if Your project or build process involves unpacking archives during remote debug sessions.
You are affected if your JetBrains Rider installation is any version earlier than 2025.1.2 AND you use or plan to use remote debug sessions with archive handling.
Generated from the published advisory. Verify against your own configuration.
