CVE-2024-53523
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 · uneditedJSFinder commit d70ab9bc5221e016c08cffaf0d9ac79646c90645 is vulnerable to Directory Traversal in the find_by_file function.
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 confidenceJSFinder's find_by_file function is vulnerable to directory traversal, allowing attackers to access files outside the intended directory by manipulating file paths using '../' sequences to escape the base 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.
-
Check if JSFinder is installedSearch for JSFinder in your environment using package managers (pip list, npm list) or by locating the jsfinder package directoryAffected if JSFinder is present in your environment
-
Determine JSFinder versionRun 'pip show jsfinder' or check package.json for version information, then compare against any known fixed versionsAffected if Version is unknown or older than any patched release
-
Identify usage of find_by_file functionSearch your codebase for calls to jsfinder.find_by_file or the module containing this function; review any scripts or applications that import and use JSFinderAffected if Your code or automation directly invokes the find_by_file function
-
Verify find_by_file is exposed to untrusted inputReview how find_by_file is called - check if user-controlled paths (URL parameters, file uploads, external input) are passed as arguments to this function without validationAffected if Untrusted input reaches the find_by_file function without sanitization
-
Test for directory traversal in find_by_file callsIf find_by_file accepts file path arguments, invoke it with a path containing '../' sequences (e.g., '../../etc/passwd') and verify if files outside the intended directory are accessible or returnedAffected if The function returns or exposes files from directories outside the expected base path
You are affected if JSFinder with the vulnerable find_by_file function is installed and exposed to untrusted input without path 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.
From vendor dataImplement strict input validation and path sanitization in the find_by_file function to ensure resolved file paths remain within the intended directory boundaries; validate that the final resolved path starts with the expected base directory.
