# Impact It is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware. # Patches * For Next.js 15.x, this issue is fixed in `15.2.3` * For Next.js 14.x, this issue is fixed in `14.2.25` * For Next.js versions `11.1.4` thru `13.5.6`, consult the below workaround. # Workaround If patching to a safe version is infeasible, it is recommend that you prevent external user requests which contain the `x-middleware-subrequest` header from reaching your Next.js application. ## Credits - Allam Rachid (zhero;) - Allam Yasser (inzo_)

### Impact In libcontainer, while creating a tenant container, the tenant builder accepts a list of capabilities to be added in the spec of tenant container. Code can be seen [here](https://github.com/youki-dev/youki/blob/9e63fa4da1672a78ca45100f3059a732784a5174/crates/libcontainer/src/container/tenant_builder.rs#L408) . The logic here adds the given capabilities to all capabilities of main container if present in spec, otherwise simply set provided capabilities as capabilities of the tenant container. However, GHSA-f3fp-gc8g-vw66 was opened on runc mentioning that setting inherited caps in any case for tenant container can lead to elevation of capabilities. For this, they added a fix [here](https://github.com/opencontainers/runc/blob/986451c24e17c8d4be3c454f60b1f7be4af3e8b4/exec.go#L234-L242) where they never set new inherited caps on tenant, and set ambient caps only if original container had inherited caps. Similarly crun never sets inherited caps as can be seen [here](https://git...

Mattermost versions 10.4.x <= 10.4.2, 10.3.x <= 10.3.3, 9.11.x <= 9.11.8 fail to enforce MFA on certain search APIs, which allows authenticated attackers to bypass MFA protections via user search, channel search, or team search queries.

Mattermost versions 9.11.x <= 9.11.8 fail to prompt for explicit approval before adding a team admin to a private channel, which team admins to joining private channels via crafted permalink links without explicit consent from them.

Mattermost versions 10.4.x <= 10.4.2, 10.3.x <= 10.3.3, 9.11.x <= 9.11.8, 10.5.x <= 10.5.0 fail to enforce MFA on plugin endpoints, which allows authenticated attackers to bypass MFA protections via API requests to plugin-specific routes.

Mattermost versions 10.4.x <= 10.4.2, 10.3.x <= 10.3.3, 9.11.x <= 9.11.8 fail to restrict command execution in archived channels, which allows authenticated users to run commands in archived channels.
