GHSA-VRGW-PC9C-QRRC
Vulnerability from github – Published: 2026-01-13 19:54 – Updated: 2026-01-16 21:54Impact
Within Umbraco Forms, configuring a malicious URL on the Webservice data source can result in Remote Code Execution. This affects all Umbraco Forms versions running on .NET Framework (up to and including version 8).
Patches
The affected Umbraco Forms versions are all End-of-Life (EOL) and not supported anymore, hence no patches will be released. Upgrading to any of the currently supported versions (v13, v16 or v17) is recommended.
Workarounds
If none of the configured Forms data sources uses the Webservice type, it can be safely excluded by adding the following code to the application. This will completely remove the option to select/use this data source within the Backoffice and thereby mitigate the vulnerability.
using Umbraco.Core.Composing;
using Umbraco.Forms.Core.Providers;
using Umbraco.Forms.Core.Providers.DatasourceTypes;
internal sealed class RemoveFormsWebserviceDataSourceTypeComposer : IUserComposer
{
public void Compose(Composition composition)
=> composition.WithCollectionBuilder<DataSourceCollectionBuilder>().Exclude<Webservice>();
}
Any Webservice data source that is configured and still in use should be replaced with a custom implementation instead, before applying the above code. If this is not feasible, the vulnerability can be minimized by revoking the 'Manage Data Sources' from any non-administrator user and/or inheriting from the default Umbraco.Forms.Core.Providers.DatasourceTypes.Webservice class and overriding the ValidateSettings() method to ensure only trusted URLs can be used.
References
When upgrading to a supported version, please take the Forms version specific upgrade notes into account and check the CMS upgrade documentation. Content and schema can also be migrated straight to the latest version using Deploy export/import with migrations.
Implementation details on data sources are not extensively documented, but they follow the general Forms provider model and inherit from Umbraco.Forms.Core.FormDataSource.

GHSA-VRR8-FP7C-7QGP
Vulnerability from github – Published: 2023-04-12 20:36 – Updated: 2023-04-18 14:35Impact
Any user with the right to add an object on a page can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of the styles properties FlamingoThemesCode.WebHome. This page is installed by default.
Reproduction Steps
Steps to reproduce:
- As a user without script or programming rights, edit your user profile with the object editor (enable advanced mode if necessary to get access) and add an object of type "Theme Class" of "FlamingoThemesCode". In the field "body-bg" (all other fields should work, too) add the following text:
{{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}
- Click "Save & View"
- Open /xwiki/bin/view/FlamingoThemesCode/WebHomeSheet where is the URL of your XWiki installation
Expected result:
The list of color themes either doesn't include the user's profile or displays a regular preview.
Actual result:
The user's profile is listed as color theme but instead of the little preview the message
Failed to execute the [html] macro. Cause: [When using HTML content inline, you can only use inline HTML content. Block HTML content (such as tables) cannot be displayed. Try leaving an empty line before and after the macro.]. Click on this message for details.
Hello from groovy!">
is displayed. This shows that a Groovy macro with content created by the user has been executed and thus demonstrates a privilege escalation from simple user account to programming rights.
Patches
The vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10.
Workarounds
The issue can be fixed by applying this patch on FlamingoThemesCode.WebHomeSheet.

Mitigation
Strategy: Refactoring
Refactor your program so that you do not have to dynamically generate code.
Mitigation
- Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product.
- Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection.
- This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise.
- Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation MIT-5
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of code injection, use stringent allowlists that limit which constructs are allowed. If you are dynamically constructing code that invokes a function, then verifying that the input is alphanumeric might be insufficient. An attacker might still be able to reference a dangerous function that you did not intend to allow, such as system(), exec(), or exit().
Mitigation
Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
Mitigation MIT-32
Strategy: Compilation or Build Hardening
Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).
Mitigation MIT-32
Strategy: Environment Hardening
Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).
Mitigation
For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures [REF-1372], so the python documentation discourages use of ast.literal_eval() on untrusted data [REF-1373].
CAPEC-242: Code Injection
An adversary exploits a weakness in input validation on the target to inject new code into that which is currently executing. This differs from code inclusion in that code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-77: Manipulating User-Controlled Variables
This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
