Cattown is Vulnerable to Uncontrolled Resource Consumption through Inefficient Regular Expression Complexity

Impact

### Overview A security review of the Cattown identified multiple weaknesses that could potentially impact its stability and security. ### Affected Versions - All versions below 1.0.2 ### Description of Vulnerabilities 1. CWE-1333: Inefficient Regular Expression Complexity The package used regular expressions with inefficient, potentially exponential worst-case complexity. This can cause excessive CPU usage due to excessive backtracking on crafted inputs, potentially leading to denial of service. 2. CWE-400: Uncontrolled Resource Consumption (Resource Exhaustion) The package was vulnerable to resource exhaustion, where processing malicious inputs could cause high CPU or memory usage, potentially leading to denial of service. ### Impact - Trigger excessive CPU consumption leading to denial of service - Cause resource exhaustion affecting service availability - Bypass protection mechanisms causing unexpected or insecure behavior ### Resolution These vulnerabilities have been fixed in version 1.0.2 of the Cattown. Users are strongly encouraged to upgrade to this version to mitigate the risks. ### Recommendations - Upgrade to Cattown version 1.0.2 or later as soon as possible. - Review and restrict input sources if untrusted inputs are processed. ### Acknowledgments The issues were proactively identified through CodeQL static analysis.
