LLM-Enabled Open-Source Systems in the Wild: An Empirical Study of Vulnerabilities in GitHub Security Advisories
This empirical study of 295 GitHub Security Advisories reveals that while LLM-integrated systems primarily exhibit traditional code-level vulnerabilities like injection and deserialization, they also present distinct architectural risks such as supply chain issues and excessive agency that are underrepresented in current disclosure frameworks, necessitating a combined CWE and OWASP perspective for comprehensive security analysis.

Imagine you've just built a magnificent, high-tech kitchen. But instead of hiring a human chef, you've installed a robot chef (a Large Language Model, or LLM) that can read your recipes, chop vegetables, and even order groceries.
The problem is, this robot chef doesn't just cook; it can also open the front door, turn on the gas, and call the police if it gets confused.
This paper is like a group of security detectives who went into the "GitHub Security Advisories" (a public bulletin board where software developers post warnings about bugs) to investigate: "When things go wrong with these robot chefs, what actually breaks, and how do we describe the danger?"
Here is the breakdown of their findings, using simple analogies:
1. The Investigation: What Did They Look At?
The researchers looked at 295 recent security warnings about software that uses these AI robot chefs. They zoomed in on 100 specific cases to understand them deeply.
They wanted to answer two big questions:
- The "Code" Question: Are there brand-new, weird types of bugs that only happen with AI?
- The "Architecture" Question: How does the way the AI is connected to the rest of the system create new dangers that standard bug reports miss?
2. Finding #1: The Bugs Are Old Friends in New Clothes
The Analogy: Imagine you buy a fancy new smart toaster. You expect it to have "smart toaster bugs," but when it breaks, it's usually just a standard electrical short or a loose wire—the same old problems as a regular toaster.
The Reality: The researchers found no new types of code bugs specific to AI.
- The most common problems were still Injection (tricking the system into doing something it shouldn't, like a hacker slipping a fake order into the robot's ear) and Deserialization (tripping over a messy data package).
- The Takeaway: The "engine" of the AI is still built with the same old, sometimes shaky, bricks as regular software. The code itself isn't magic; it's just code.
3. Finding #2: The "Warning Labels" Are Missing
The Analogy: Imagine a warning label on a car that says, "Warning: If you press the brake, the car might stop." That's true, but it doesn't tell you that this specific car is also connected to a drone that will drop a bomb if you press the brake too hard.
The Reality: The current security warnings (GitHub Advisories) are great at saying, "This piece of code has a hole in it." But they are terrible at saying, "Because this code is connected to an AI, that hole now lets the AI accidentally delete your database."
- The standard labels (called CWE) describe the hole in the wall.
- They don't describe the path the AI takes to walk through that hole and cause chaos.
4. Finding #3: The Real Danger is the "Chain Reaction"
The Analogy: Think of the AI as a middleman in a busy office.
- Scenario A: You tell the middleman, "Call the boss." (Normal)
- Scenario B: A hacker whispers, "Call the boss and tell him to give you his password." (Prompt Injection)
- Scenario C: The middleman is so eager to please that they call the boss and the bank and the fire department without checking if it's safe. (Excessive Agency)
The Reality: When the researchers used a new checklist called OWASP Top 10 for LLMs, they found the real risks weren't just the code bugs. They were about how the AI behaves:
- Supply Chain Risks (44%): The biggest danger is that the AI is using tools or libraries that someone else wrote, and those tools are broken. It's like your robot chef using a knife that was made by a shady factory.
- Excessive Agency (20%): The AI is given too much power. It's like giving a toddler the keys to the car and the house.
- Prompt Injection (18%): Tricking the AI into ignoring its rules.
5. The Big Picture: Two Maps Are Better Than One
The researchers concluded that we need two different maps to understand the danger:
- The "Code Map" (CWE): Tells you where the bricks are cracked. (e.g., "This function is unsafe.")
- The "Behavior Map" (OWASP): Tells you how the AI uses those cracked bricks to cause trouble. (e.g., "Because the AI can run commands, that unsafe function lets it hack the server.")
The Final Lesson:
If you only look at the code, you miss the fact that the AI is the "wild card" that turns a small glitch into a massive disaster. If you only look at the AI behavior, you miss the fact that the underlying code is what actually breaks.
In short: AI doesn't invent new kinds of bugs; it just takes our old, familiar bugs and gives them a superpower to cause much more damage. To stay safe, we need to fix the code and understand how the AI is allowed to use it.
