Smokescreen is a simple HTTP proxy that fogs over naughty URLs. The primary use case for Smokescreen is to prevent server-side request forgery (SSRF) attacks in which external attackers leverage the behavior of applications to connect to or scan internal infrastructure. Smokescreen also offers an option to deny access to additional (e.g., external) URLs by way of a deny list. There was an issue in Smokescreen that made it possible to bypass the deny list feature by appending a dot to the end of user-supplied URLs, or by providing input in a different letter case. Recommended to upgrade Smokescreen to version 0.0.3 or later.

Stripe CLI is a command-line tool for the Stripe eCommerce platform. A vulnerability in Stripe CLI exists on Windows when certain commands are run in a directory where an attacker has planted files. The commands are `stripe login`, `stripe config -e`, `stripe community`, and `stripe open`. MacOS and Linux are unaffected. An attacker who successfully exploits the vulnerability can run arbitrary code in the context of the current user. The update addresses the vulnerability by throwing an error in these situations before the code can run.Users are advised to upgrade to version 1.7.13. There are no known workarounds for this issue.

Default SilverStripe GraphQL Server (aka silverstripe/graphql) 3.x through 3.4.1 permission checker not inherited by query subclass.

SilverStripe Framework through 4.8.1 allows XSS.

In SilverStripe through 4.6.0-rc1, GraphQL doesn't honour MFA (multi-factor authentication) when using basic authentication.

In SilverStripe through 4.6.0-rc1, a FormField with square brackets in the field name skips validation.

SilverStripe through 4.6.0-rc1 has an XXE Vulnerability in CSSContentParser. A developer utility meant for parsing HTML within unit tests can be vulnerable to XML External Entity (XXE) attacks. When this developer utility is misused for purposes involving external or user submitted data in custom project code, it can lead to vulnerabilities such as XSS on HTML output rendered through this custom code. This is now mitigated by disabling external entities during parsing. (The correct CVE ID year is 2020 [CVE-2020-25817, not CVE-2021-25817]).

vscode-stripe is an extension for Visual Studio Code. A vulnerability in Stripe for Visual Studio Code extension exists when it loads an untrusted source-code repository containing malicious settings. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. The update addresses the vulnerability by modifying the way the extension validates its settings.

In SilverStripe through 4.5.0, a specific URL path configured by default through the silverstripe/framework module can be used to disclose the fact that a domain is hosting a Silverstripe application. There is no disclosure of the specific version. The functionality on this URL path is limited to execution in a CLI context, and is not known to present a vulnerability through web-based access. As a side-effect, this preconfigured path also blocks the creation of other resources on this path (e.g. a page).

Silverstripe CMS through 4.5 can be susceptible to script execution from malicious upload contents under allowed file extensions (for example HTML code in a TXT file). When these files are stored as protected or draft files, the MIME detection can cause browsers to execute the file contents. Uploads stored as protected or draft files are allowed by default for authorised users only, but can also be enabled through custom logic as well as modules such as silverstripe/userforms. Sites using the previously optional silverstripe/mimevalidator module can configure MIME whitelists rather than extension whitelists, and hence prevent this issue. Sites on the Common Web Platform (CWP) use this module by default, and are not affected.
