Firefox could have incorrectly parsed a URL and rewritten it to the youtube.com domain when parsing the URL specified in an `embed` tag. This could have bypassed website security checks that restricted which domains users were allowed to embed. This vulnerability was fixed in Firefox 140, Firefox ESR 128.12, Thunderbird 140, and Thunderbird 128.12.Show less

WilderForge is a Wildermyth coremodding API. A critical vulnerability has been identified in multiple projects across the WilderForge organization. The issue arises from unsafe usage of `${{ github.event.review.body }}` and other user controlled variables directly inside shell script contexts in GitHub Actions workflows. This introduces a code injection vulnerability: a malicious actor submitting a crafted pull request review containing shell metacharacters or commands could execute arbitrary shell code on the GitHub Actions runner. This can lead to arbitrary command execution with the permissions of the workflow, potentially compromising CI infrastructure, secrets, and build outputs. Developers who maintain or contribute to the repos WilderForge/WilderForge, WilderForge/ExampleMod, WilderForge/WilderWorkspace, WilderForge/WildermythGameProvider, WilderForge/AutoSplitter, WilderForge/SpASM, WilderForge/thrixlvault, WilderForge/MassHash, and/or WilderForge/DLC_Disabler; as well as users who fork any of the above repositories and reuse affected GitHub Actions workflows, are affected. End users of any the above software and users who only install pre-built releases or artifacts are not affected. This vulnerability does not impact runtime behavior of the software or compiled outputs unless those outputs were produced during exploitation of this vulnerability. A current workaround is to disable GitHub Actions in affected repositories, or remove the affected workflows.Show less

Discourse is an open-source discussion platform. Prior to version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch, certain invites via email may result in HTML injection in the email body if the topic title includes HTML. This includes inviting someone (without an account) to a PM and inviting someone (without an account) to a topic with a custom message. This issue is patched in version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch. This can be worked around if the relevant templates are overridden without `{topic_title}`.Show less

Umbraco Forms is a form builder that integrates with the Umbraco content management system. Starting in the 7.x branch and prior to versions 13.4.2 and 15.1.2, the 'Send email' workflow does not HTML encode the user-provided field values in the sent email message, making any form with this workflow configured vulnerable, as it allows sending the message from a trusted system and address, potentially bypassing spam and email client security systems. This issue affects all (supported) versions Umbraco Forms and is patched in 13.4.2 and 15.1.2. Unpatched or unsupported versions can workaround this issue by using the `Send email with template (Razor)` workflow instead or writing a custom workflow type. To avoid accidentally using the vulnerable workflow again, the `SendEmail` workflow type can be removed using a composer available in the GitHub Security Advisory for this vulnerability.Show less

Misskey is an open source, federated social media platform. Starting in version 12.0.0 and prior to version 2025.4.1, due to an oversight in the validation performed in `UrlPreviewService` and `MkUrlPreview`, it is possible for an attacker to inject arbitrary CSS into the `MkUrlPreview` component. `UrlPreviewService.wrap` falls back to returning the original URL if it's using a protocol that is likely to not be understood by Misskey, IE something other than `http` or `https`. This both can de-anonymize users and_allow further attacks in the client. Additionally, `MkUrlPreview` doesn't escape CSS when applying a `background-image` property, allowing an attacker to craft a URL that applies arbitrary styles to the preview element. Theoretically, an attacker can craft a CSS injection payload to create a fake error message that can deceive the user into giving away their credentials or similar sensitive information. Version 2025.4.1 contains a patch for the issue.Show less

XWiki is a generic wiki platform. In versions starting from 15.9-rc-1 to before 15.10.8 and from 16.0.0-rc-1 to before 16.2.0, the required rights analysis doesn't consider TextAreas with default content type. When editing a page, XWiki warns since version 15.9 when there is content on the page like a script macro that would gain more rights due to the editing. This analysis doesn't consider certain kinds of properties, allowing a user to put malicious scripts in there that will be executed after a user with script, admin, or programming rights edited the page. Such a malicious script could impact the confidentiality, integrity and availability of the whole XWiki installation. This issue has been patched in versions 15.10.8 and 16.2.0.Show less

Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. For a subset of unlikely rewrite rule configurations, it was possible for a specially crafted request to bypass some rewrite rules. If those rewrite rules effectively enforced security constraints, those constraints could be bypassed. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.5, from 10.1.0-M1 through 10.1.39, from 9.0.0.M1 through 9.0.102. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.Show less
