Exploitability
| CWE ID | Description |
|---|---|
| CWE-416 | The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in quickjs occurs in the js_print_object function when printing arrays, maps, or sets. The function fetches the length or iterates over elements, but printing a value can trigger attacker-defined callbacks that modify the array or list during iteration. This can cause out-of-bounds access and use-after-free errors.
How can this vulnerability impact me? :
The vulnerability can lead to use-after-free conditions, which may allow attackers to execute arbitrary code, cause crashes, or corrupt memory, potentially compromising the security and stability of applications using quickjs.
