• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.1% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2024-11-13 · updated 2026-06-17
• Weakness: CWE-94

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.
