Hi,

The following vulnerability was published for lambdaisland-uri-clojure.

CVE-2023-28628[0]:
| lambdaisland/uri is a pure Clojure/ClojureScript URI library. In
| versions prior to 1.14.120 `authority-regex` allows an attacker to
| send malicious URLs to be parsed by the `lambdaisland/uri` and
| return the wrong authority. This issue is similar to but distinct
| from CVE-2020-8910. The regex in question doesn't handle the
| backslash (`\`) character in the username correctly, leading to a
| wrong output. ex. a payload of `https://example.com\\@google.com`
| would return that the host is `google.com`, but the correct host
| should be `example.com`. Given that the library returns the wrong
| authority this may be abused to bypass host restrictions depending
| on how the library is used in an application. Users are advised to
| upgrade. There are no known workarounds for this vulnerability.
