Uncontrolled Resource Consumption
CVE-2025-58451
Summary
Cattown is a JavaScript markdown parser. Versions prior to 1.0.2 used Regular Expressions with Inefficient, potentially exponential worst-case complexity. This could cause excessive CPU usage due to excessive backtracking on crafted inputs. In turn, the excessive CPU usage could lead to resource exhaustion, where processing malicious inputs could cause high CPU or memory usage, potentially leading to Denial-of-Service (DoS). Additionally, users should review and restrict input sources if untrusted inputs are processed.

CWE-400 - Uncontrolled resource consumption
An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
