The best way to fix the problem is to ensure that the constructed consoleUrl is always a safe URL—specifically, that it uses the desired protocol and does not allow for injection of dangerous values (such as javascript: or data:). This is usually achieved by performing output encoding or protocol checking before using a value as an anchor href. In this particular case:
- We can implement a helper function, e.g.,
sanitizeUrl, that checks the format/protocol ofconsoleUrl, ensuring it starts with expected roots (e.g.,/v2orhttps://orhttp://), and defaults to a safe value if not. - In the code, wrap the calculated
consoleUrlwith this sanitization function to guarantee that even if user-controlled data is used in the URL, it cannot result in an unsafe link. - The fix only affects the construction and use of
consoleUrl, requiring at most a helper function and minor changes to the returned anchor tag in JSX. - No change in visible behavior for valid URLs; only malicious (or invalid) URLs will be neutralized.
For best security and clarity, place the sanitizeUrl function in this file above the component definition, with clear documentation.
