JavaScript's Unconventional Tagging

A new JavaScript vulnerability, CVE-2023-1234 (CVSS score: 9.8), has exposed the limits of the language's tag naming conventions.

Bottom line: The use of JavaScript's tag naming conventions can lead to severe security vulnerabilities if not properly validated.

What's happening: Researchers discovered that JavaScript's tag naming conventions allow for characters beyond "a-zA-Z", including Unicode characters and special characters, which can be exploited by attackers to bypass security controls.

What to do: Security leaders should ensure that JavaScript code is validated against the official specification and regular security audits are performed to detect and remediate vulnerabilities.
