A critical security advisory from Red Hat addresses multiple vulnerabilities in the Migration Toolkit for Applications (MTA), a solution that facilitates application modernization and migration to Red Hat OpenShift. The advisory references a broad set of CVEs affecting MTA, covering various security weaknesses. A new version of MTA is available that fixes these issues. Users are advised to apply this update after ensuring all prior relevant errata are installed.

### Impact `fast-uri` versions `>= 2.3.1, <= 4.0.0` fail to canonicalize Unicode/IDN hostnames for HTTP-family URLs. The IDN conversion path calls `URL.domainToASCII(...)` on the global WHATWG `URL` constructor, where that helper does not exist. The resulting `TypeError` is silently routed into `parsed.error`, but `parse()`, `normalize()`, and `equal()` all return with the host left in its original Unicode form. For example, `http://127。0。0。1/` is treated by `fast-uri` as host `127。0。0。1`, while Node's WHATWG URL parser and `fetch()` canonicalize the same input to `127.0.0.1`. Applications that use `fast-uri` to enforce host-based policy (denylists, loopback filtering, redirect validation, outbound proxy routing) before passing the same URL into Node's URL or `fetch()` consumers see a policy/use desync and can be steered to an unintended destination. ### Patches Upgrade to `fast-uri` v4.0.1, v3.1.3, or v2.4.2 ### Workarounds None. Upgrade to the patched version.
