Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.4, Authlib’s JWS verification accepts tokens that declare unknown critical header parameters (crit), violating RFC 7515 “must‑understand” semantics. An attacker can craft a signed token with a critical header (for example, bork or cnf) that strict verifiers reject but Authlib accepts. In mixed‑language fleets, this enables split‑brain verification and can lead to policy bypass, replay, or privilege escalation. This issue has been patched in version 1.6.4.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions prior to 14.10.4 it's possible to exploit well known parameters in XWiki URLs to perform redirection to untrusted site. This vulnerability was partially fixed in the past for XWiki 12.10.7 and 13.3RC1 but there is still the possibility to force specific URLs to skip some checks, e.g. using URLs like `http:example.com` in the parameter would allow the redirect. The issue has now been patched against all patterns that are known for performing redirects. This issue has been patched in XWiki 14.10.4 and 15.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Redash is a package for data visualization and sharing. In Redash version 10.0 and prior, the implementation of Google Login (via OAuth) incorrectly uses the `state` parameter to pass the next URL to redirect the user to after login. The `state` parameter should be used for a Cross-Site Request Forgery (CSRF) token, not a static and easily predicted value. This vulnerability does not affect users who do not use Google Login for their instance of Redash. A patch in the `master` and `release/10.x.x` branches addresses this by replacing `Flask-Oauthlib` with `Authlib` which automatically provides and validates a CSRF token for the state variable. The new implementation stores the next URL on the user session object. As a workaround, one may disable Google Login to mitigate the vulnerability.

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.

Following the redirect response, the new request is still filtered by the SWG policy.
