All versions of `@hapi/content` through 6.0.0 are vulnerable to Regular Expression Denial of Service (ReDoS) via crafted HTTP header values. Three regular expressions used to parse `Content-Type` and `Content-Disposition` headers contain patterns susceptible to catastrophic backtracking. This has been fixed in v6.0.1. ### Impact Denial of Service. An unauthenticated remote attacker can cause a Node.js process to become unresponsive by sending a single HTTP request with a maliciously crafted header value. ### Patches Fixed by tightening all three regular expressions to eliminate backtracking. ### Workarounds There are no known workarounds. Upgrade to the patched version.
