Technical description

Trilium is an open-source hierarchical note-taking application. In versions prior to 0.104.0, the default-on "Safe import" filter fails to neutralize the shareTemplate relation because that relation is not marked as dangerous, allowing an attacker-supplied import archive to plant a server-side template that leads to remote code execution. The relation is omitted from the built-in list of dangerous attributes, so unlike other code-loading relations it is not disabled on import, and when the victim later publishes the imported note the public share renderer feeds the linked EJS code note's raw bytes into ejs.render, which compiles them in the server's Node process. An unauthenticated request to the shared note then executes the attacker's JavaScript with full access to require, process, the filesystem, and the network. This issue is fixed in version 0.104.0.

———A weakness has been identified in RooCodeInc Roo-Code up to 3.51.1. Affected by this issue is the function ExecaTerminalProcess of the component README File Handler. Executing a manipulation can lead to code injection. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks. Multiple isses were reported to the vendor beforehand. They explain, that "they all apply to Roo Code, a project we no longer support - the repository was archived a while ago, and we don't encourage anyone to use it." This vulnerability only affects products that are no longer supported by the maintainer.5h CVE-2026-818335.5 MED

———A security flaw has been discovered in RooCodeInc Roo-Code up to 3.51.1. Affected by this vulnerability is the function optimizeQuery of the file src/utils/helpers.ts of the component CodeIndexManager. Performing a manipulation results in code injection. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. Multiple isses were reported to the vendor beforehand. They explain, that "they all apply to Roo Code, a project we no longer support - the repository was archived a while ago, and we don't encourage anyone to use it."

———Silverstripe UserForms provides a visual form builder for the Silverstripe CMS. From 6.0.0 until 6.4.9, 7.0.7, and 7.1.1, the userform email recipient subject field in the CMS accepts a specially crafted payload that can be interpreted as executable server-side code. An authenticated CMS user with permission to configure a UserForms email recipient can use the subject field to run arbitrary code on the server, compromising confidentiality, integrity, and availability. This issue is fixed in versions 6.4.9, 7.0.7, and 7.1.1.5h CVE-2026-547187.2 HIG

———Silverstripe Advanced Workflow is a highly configurable step-based workflow module. Prior to 6.4.5, 7.1.3, and 7.2.1, an attacker with permission to author the advanced workflow email template can place a specially crafted server-side template payload in NotifyUsersWorkflowAction.EmailTemplate. When NotifyUsersWorkflowAction renders the field through the Silverstripe template engine SSTemplateParser, the payload can cause PHP evaluation and arbitrary code execution on the server; the regression coverage is in tests/php/WorkflowEngineTest.php. This issue is fixed in versions 6.4.5, 7.1.3, and 7.2.1.5h CVE-2026-53579—

———Trilium is an open-source hierarchical note-taking application. In versions up to and including 0.103.0, the default-on "Safe import" filter sanitizes HTML only for text notes and excludes the book note type, whose content is stored without sanitization and later rendered as HTML, allowing an attacker-supplied import archive to embed a payload that executes as script. A book note's content is routed through the same rendering path as text notes and injected into the page with jQuery's html method when the note is shown as a grid-view preview card, so a malicious note survives Safe import and runs as soon as the victim opens the containing note. On the desktop client the Electron renderer runs with Node integration enabled, so the injected JavaScript escalates from cross-site scripting to full remote code execution on the victim's machine. This issue is fixed in version 0.104.0.5h CVE-2026-53578—

———Trilium is an open-source hierarchical note-taking application. In versions up to and including 0.103.0, the default-on "Safe import" filter sanitizes HTML only for text notes and excludes the mindMap note type, whose JSON content is stored without sanitization, allowing an attacker-supplied import archive to embed a payload that renders as arbitrary HTML. A mind map node can carry a dangerouslySetInnerHTML property that the Mind Elixir library assigns directly to a node's innerHTML, so a malicious note survives Safe import and executes script as soon as the victim opens the imported mind map. On the desktop client the Electron renderer runs with Node integration enabled, so the injected JavaScript escalates from cross-site scripting to full remote code execution on the victim's machine.
