The Premium Addons for Elementor plugin for WordPress is vulnerable to Regular Expression Denial of Service (ReDoS) in all versions up to, and including, 4.10.35. This is due to processing user-supplied input as a regular expression. This makes it possible for authenticated attackers, with Author-level access and above, to create and query a malicious post title, resulting in slowing server resources.
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Premium_addons_for_elementor | Leap13 | * | 4.10.36 (excluding) |
Attackers can create crafted inputs that
intentionally cause the regular expression to use
excessive backtracking in a way that causes the CPU
consumption to spike.
