r/learnpython on Reddit: Potential Security Risks of using Python at Work
January 21, 2025 -
So I wanted to install Python, download Selenium library on it, and combine it with Webdriver to access web-driven accounting software to automate some stuff; mainly downloading reports from the accounting software since there are tones of reports to download every month, which the software does not have automation function for. I don't want to deal with any data.
Senior director and I went to IT for the request to download Python and they declined; they said there is a security risk.
Does anyone know what potential security risks they are referring to? I don't have cs background so I'm not very sure. And is there a way to mitigate those risks?

A few people have given plausible guesses, but the fact is we can't know how to answer this because we don't know where you work, what systems you're trying to install python and what the security requirements of those systems are. There are a million possible reasons the IT people responsible for security might not want a general-purpose programming environment on a given system. Unfortunately, you have to ask them which ones they are actually concerned about.

I feel like you should be asking your IT, not reddit. Regardless, you're using open source resources, if those get compromised, who will be responsible? It would be IT, because they were the ones to allow it. If your senior director is willing to sign some paperwork, placing all financial data breaches due to the use of your tool as their responsibility, then I'm certain IT would be more willing. My additional guess, is that your senior director will not sign such paperwork either.

This means that attacker-controlled virtual environments are able to run commands when the virtual environment is activated. Virtual environments which are not created by an attacker or which aren't activated before being used (ie "./venv/bin/python") are not affected. ...

r/Python on Reddit: Corporate IT have banned all versions of python lower than the latest
November 21, 2023 -
I.e. right now they are insisting we use v3.12 only because older versions have some vulnerabilities their scanner picked up.
I need to somehow explain that this is a terrible idea and that many packages won't support the most up to date version without causing them to panic and overstep even more.
This requirement is company wide (affects development, data science and analytics).
Edit - thanks for all the advice, I think the crux is that they don't understand how the versioning works and are confusing major and minor versions. I will explain this and hopefully we will be able to use the latest minor versions for 3.11/3.10/3.9

Don't know what your environments look like, but we upgraded almost all of ours to 3.12, I would definitely recommend it. Most packages are already up to date. That being said, if IT doesn't understand why you might need to run 3.11 for some packages, can't you simply provide them a list of the packages that don't support 3.12 and tell them you'll upgrade those systems when their dependencies catch up?

And yet some corporate IT have also banned all Python newer than 2.7.

March 30, 2022 - As example Python library, the Requests package (who doesn’t use this one?) before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network. ... This vulnerability can be fixed by updating (and testing!) all the packages for which updates are available. (DUH!) You can also use tools to help with this after the fact: Static application security testing (SAST) – static test that happens without executing the code.
