CVE-2022-31570
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 · uneditedThe adriankoczuruek/ceneo-web-scrapper repository through 2021-03-15 on GitHub allows absolute path traversal because the Flask send_file function is used unsafely.
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 confidenceThe ceneo-web-scrapper Flask application contains a path traversal vulnerability due to unsafely using the send_file function without proper input validation. This allows attackers to access arbitrary files on the server file system by manipulating file paths in requests.

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 ceneo-web-scrapper installationSearch for the ceneo-web-scrapper application in your environment, checking deployed web applications, source code repositories, or container images.Affected if The application is present in your environment
-
Determine application version or deployment dateCheck the version information or deployment timestamp of the ceneo-web-scrapper application. Compare against the affected range (versions or deployments dated 2021-03-15 or earlier).Affected if The version or deployment date is on or before 2021-03-15
-
Locate Flask send_file usage in application codeSearch the application source code for usage of Flask's send_file function, particularly in file download or serving endpoints.Affected if The application uses send_file to serve files to users
-
Inspect path handling in send_file callsExamine the code paths leading to send_file calls to determine if user input is used directly to construct the file path without validation using methods like os.path.abspath or directory containment checks.Affected if User-controllable input flows to send_file without proper path sanitization
-
Verify network exposure of the applicationDetermine if the Flask application is accessible over a network. Check firewall rules, reverse proxy configurations, and whether the application binds to a network interface.Affected if The application is network-accessible without additional authentication protecting the vulnerable endpoints
You are affected if the ceneo-web-scrapper application is deployed in your environment with a version or deployment date on or before 2021-03-15 and contains send_file usage that processes user input without path sanitization.

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 path validation and sanitization before passing paths to Flask's send_file function, ensuring requested files are within the intended directory using methods like os.path.abspath and directory containment checks.
