CVE-2022-31577
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 longmaoteamtf/audio_aligner_app repository through 2020-01-10 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 · high confidenceThe audio_aligner_app Flask application contains an absolute path traversal vulnerability caused by unsafe usage of Flask's send_file function. An attacker can supply absolute file paths to access sensitive files outside the intended web root directory, leading to potential disclosure of system files, configuration files, or other sensitive data.

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 if Audio Aligner App is installedSearch for the audio_aligner_app project files in your environment. Common locations include /opt, /var/www, user home directories, or Python site-packages. Look for directories or packages named 'audio_aligner_app' or 'audio-aligner'.Affected if The application is present in your environment
-
Determine the installed versionCheck the version of the installed audio_aligner_app. Look for version information in setup.py, __init__.py, requirements.txt, or a VERSION file within the application directory. Compare against the affected version: <= 2020-01-10Affected if The version is 2020-01-10 or earlier, or no version is found (indicating an old installation)
-
Inspect source code for vulnerable send_file usageSearch the application source code for calls to Flask's send_file function. Specifically look for patterns where send_file receives a path parameter directly without validation, such as: send_file(path) or send_file(request.args.get('path')). Use grep or a text search for 'send_file' in .py files.Affected if send_file is called with unvalidated path input, especially when accepting file paths from user requests
-
Verify if the application is web-exposedCheck if the Flask application is running and accessible over HTTP/HTTPS. Look for running processes listening on ports (commonly 5000), or check your web server configuration for proxied routes to audio_aligner_app.Affected if The application is running and network-accessible (even locally), as the vulnerability is exploitable via HTTP requests
You are affected if Audio Aligner App version 2020-01-10 or earlier is installed and the vulnerable send_file pattern exists in the code accessible over a network.

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 dataReplace unsafe send_file calls with send_from_directory which performs path validation, or implement strict path sanitization/validation to ensure requests remain within allowed directories before passing paths to send_file.
