JetBrains Warns of GitHub Plugin that Exposes Access Tokens

A critical vulnerability (CVE-2024-37051) in the JetBrains GitHub plugin for IntelliJ-based IDEs (2023.1 and later) exposed access tokens to malicious content within GitHub pull requests, allowing attackers to steal tokens and potentially compromise linked accounts, even with two-factor authentication enabled. 

JetBrains has addressed the issue with a patch and collaborated with GitHub on mitigation efforts.

Users are advised to update their IDEs and consider revoking any GitHub tokens used by the plugin. 

They have provided available fixed versions for JetBrains IDEs as of today, while Aqua currently has a single fixed version available, 2024.1.2.

CLion offers multiple fixed versions, spanning from 2023.1.7 all the way up to the latest Early Access Program (EAP) build, 2024.2 EAP2. DataGrip and DataSpell each have a fixed version from the current year (2024.1.4 and 2024.1.2, respectively). 

GoLand and IntelliJ IDEA users benefit from a wider range of fixed versions, including those from 2023 and the current EAP builds for 2024.2.

Finally, MPS offers fixed versions starting in the middle of 2023 (2023.2.1), with the latest being an EAP build from the current year (2024.1 EAP2).  

A security vulnerability in the JetBrains GitHub plugin that could expose access tokens has been patched, which affects all IntelliJ-based IDEs (including PhpStorm, PyCharm, Rider, RubyMine, WebStorm, and RustRover) from version 2023.1 onwards. 

The JetBrains GitHub plugin has been updated with the fix, and insecure versions have been removed from the JetBrains Marketplace.

Users are strongly recommended to update the plugin to the latest version immediately. 

An external security report submitted on May 29, 2024, identified a vulnerability (CVE-2024-37051) in the JetBrains GitHub plugin for IntelliJ-based IDEs (version 2023.1 and later). 

The vulnerability could expose a user’s GitHub access token to a malicious third-party if a pull request containing malicious content is handled by the IDE, while updating to the latest IDE version is strongly recommended to mitigate this vulnerability. 

JetBrains identified a security vulnerability in their GitHub plugin for IntelliJ-based IDEs (versions 2023.1 and later) that could expose access tokens, and to mitigate this issue, they contacted GitHub and implemented measures that might cause the plugin to malfunction in older IDE versions. 

While a permanent fix is underway, updating the plugin and IDE to the latest versions is crucial to ensuring security and full functionality. 

To ensure compatibility and security when using the JetBrains IDE GitHub integration plugin, update to the latest IDE version, and if you’ve used the plugin’s pull request features, revoke any associated GitHub tokens. 

The plugin might use OAuth or Personal Access Tokens (PATs). Revoke them through GitHub’s application settings or token management page.

Note that revoking tokens disables all plugin features, including Git operations, requiring reconfiguration.
