A request smuggling vulnerability existed in the Google Cloud Classic Application Load Balancer due to improper handling of chunked-encoded HTTP requests. This allowed attackers to craft requests that could be misinterpreted by backend servers. The issue was fixed by disallowing stray data after a chunk, and is no longer exploitable. No action is required as Classic Application Load Balancer service after 2025-04-26 is not vulnerable.

Flask-AppBuilder is an application development framework built on top of Flask. Versions prior to 4.6.2 would allow for a malicious unauthenticated actor to perform an open redirect by manipulating the Host header in HTTP requests. Flask-AppBuilder 4.6.2 introduced the `FAB_SAFE_REDIRECT_HOSTS` configuration variable, which allows administrators to explicitly define which domains are considered safe for redirection. As a workaround, use a reverse proxy to enforce trusted host headers.

Nextcloud Server is a self hosted personal cloud system. Nextcloud Server prior to 29.0.15, 30.0.9, and 31.0.3 and Nextcloud Enterprise Server prior to 26.0.13.15, 27.1.11.15, 28.0.14.6, 29.0.15, 30.0.9, and 31.0.3 have a bug with session handling. The bug caused skipping the second factor confirmation after a successful login with the username and password when the server was configured with `remember_login_cookie_lifetime` set to `0`, once the session expired on the page to select the second factor and the page is reloaded. Nextcloud Server 29.0.15, 30.0.9, and 31.0.3 and Nextcloud Enterprise Server is upgraded to 26.0.13.15, 27.1.11.15, 28.0.14.6, 29.0.15, 30.0.9 and 31.0.3 contain a patch. As a workaround, set the `remember_login_cookie_lifetime` in config.php to a value other than `0`, e.g. `900`. Beware that this is only a workaround for new sessions created after the configuration change. System administration can delete affected sessions.

In the Linux kernel, the following vulnerability has been resolved:
net_sched: hfsc: Fix a UAF vulnerability in class with netem as child qdisc
As described in Gerrard's report [1], we have a UAF case when an hfsc class
has a netem child qdisc. The crux of the issue is that hfsc is assuming
that checking for cl->qdisc->q.qlen == 0 guarantees that it hasn't inserted
the class in the vttree or eltree (which is not true for the netem
duplicate case).
This patch checks the n_active class variable to make sure that the code
won't insert the class in the vttree or eltree twice, catering for the
reentrant case.
