What is CVE-2024-21541?
CVE-2024-21541 is a medium-severity code injection vulnerability in dom-iterator, published on 13 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Versions of the package dom-iterator before 1.0.1 are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Function generates a new function body and thus care must be given to ensure that the inputs to Function are not attacker-controlled. The risks involved are similar to that of allowing attacker-controlled input to reach eval.
Weakness: CWE-94
