A low-severity vulnerability has been identified in Vue 2: CVE-2024-9506. This vulnerability affects the Vue 2 compiler and can lead to a Regular Expression Denial of Service (ReDoS) attack when improperly written regex is triggered by specific template strings.

Vulnerability Details
The ReDoS issue arises in Vue’s parseHTML() function within the following components:
