CVE-2023-39584
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 · uneditedHexo up to v7.0.0 (RC2) was discovered to contain an arbitrary file read vulnerability.
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 · low confidenceHexo static site generator up to version 7.0.0 RC2 contains an arbitrary file read vulnerability that allows unauthenticated attackers to read sensitive files on the server. The vulnerability likely stems from insufficient path validation in file processing functionality, enabling path traversal attacks.

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 Hexo versionRun `hexo version` or inspect the `package.json` file in your project for the `hexo` package version entryAffected if The reported version is 7.0.0 or any version 6.3.0 or lower
-
Verify if custom plugins handle file pathsExamine the `node_modules/hexo` directory and any custom plugins in `node_modules/` for code that reads files based on user input or URL parameters, particularly look for usage of `fs.readFile` or similar file operations with unsanitized path variablesAffected if Custom plugins or themes that process file paths from external input are installed and active
-
Check for exposed file processing endpointsReview your Hexo deployment configuration and any server-side customizations that might handle file path requests, such as custom routing in `_config.yml` or server middlewareAffected if Any endpoint or route accepts file path parameters without validation that could be exploited for path traversal
-
Inspect theme and asset loading mechanismsLook at theme configuration files and any code that dynamically loads templates, layouts, or assets from user-influenced pathsAffected if The theme system or asset pipeline uses unsanitized path inputs to locate files on the filesystem
You are affected if your Hexo installation is version 7.0.0 or version 6.3.0 or lower AND your deployment exposes any functionality that processes file paths from external input without validation.

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 to a patched Hexo version that addresses the arbitrary file read vulnerability. If no upgrade is available, implement input validation and path traversal safeguards on file access operations.
Hexo 7.0.1 or later (latest stable 7.x release)
- 1. Back up your Hexo project completely before upgrading
- 2. Check your current Hexo version by running: hexo version
- 3. Upgrade Hexo to the latest version using: npm install hexo-cli -g
- 4. Verify the upgrade was successful by running: hexo version
- 5. Test your site's generation functionality: hexo clean && hexo generate
- 6. Review your generated site to ensure all functionality works as expected
