CyberRota Analysis
AI-GeneratedCyberChef versions prior to 11.3.0 are vulnerable to a denial-of-service condition caused by a malformed #recipe= URL fragment that can lead to excessive CPU usage in the client's browser, potentially freezing the tab during startup. While this vulnerability does not allow for code execution, data exfiltration, or privilege escalation, it can significantly disrupt user experience. Organizations using CyberChef should prioritize upgrading to version 11.3.0 to mitigate this issue.

Original NVD Description
CyberChef is a web app for encryption, encoding, compression, and data analysis. Prior to 11.3.0, CyberChef's pretty-recipe parser in src/core/Utils.mjs can exhaust client-side CPU when a malformed #recipe= URL fragment containing a large number of unmatched quote characters reaches Utils.parseRecipeConfig(). The function synchronously applies a complex global regular expression that may perform heavy backtracking before rejecting the input, causing the victim's browser tab to freeze during startup for seconds or longer. No code execution, data exfiltration, or privilege escalation occurs. This issue is fixed in version 11.3.0.
