Check the Dependency Dashboard for more information. ### GitHub Vulnerability Alerts #### [CVE-2024-1681](https://nvd.nist.gov/vuln/detail/CVE-2024-1681) corydolphin/flask-cors is vulnerable to log injection when the log level is set to debug. An attacker can inject fake log entries into the log file by sending a specially crafted GET request containing a CRLF sequence in the request path. This vulnerability allows attackers to corrupt log files, potentially covering tracks of other attacks, confusing log post-processing tools, and forging log entries. The issue is due to improper output neutralization for logs. --- ### Release Notes <details> <summary>corydolphin/flask-cors (flask-cors)</summary> ### [`v4.0.1`](https://togithub.com/corydolphin/flask-cors/blob/HEAD/CHANGELOG.md#401) [Compare Source](https://togithub.com/corydolphin/flask-cors/compare/4.0.0...4.0.1) ##### Security - Address [CVE-2024-1681](https://togithub.com/advisories/GHSA-84pr-m4jr-85g5) which is a log injection vulnerability when the log level is set to debug by [@​aneshujevic](https://togithub.com/aneshujevic) in [https://github.com/corydolphin/flask-cors/pull/351](https://togithub.com/corydolphin/flask-cors/pull/351) ### [`v4.0.0`](https://togithub.com/corydolphin/flask-cors/blob/HEAD/CHANGELOG.md#400) [Compare Source](https://togithub.com/corydolphin/flask-cors/compare/3.0.10...4.0.0) - Remove support for Python versions older than 3.8 by [@​WAKayser](https://togithub.com/WAKayser) in [https://github.com/corydolphin/flask-cors/pull/330](https://togithub.com/corydolphin/flask-cors/pull/330) - Add GHA tooling by [@​corydolphin](https://togithub.com/corydolphin) in [https://github.com/corydolphin/flask-cors/pull/331](https://togithub.com/corydolphin/flask-cors/pull/331) </details> --- ### Configuration 📅 **Schedule**: Branch creation - "" (UTC), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

Hi @corydolphin
In this PR I've used Python's repr method to escape special characters and print them as ordinary characters as a bugfix for CVE-2024-1681 - https://nvd.nist.gov/vuln/detail/CVE-2024-1681.
This should resolve #349.
