In Eclipse Theia versions up to and including 1.73.1, the @theia/filesystem backend exposes HTTP file-download endpoints (GET /file, GET /files/, PUT /files/) that convert a client-supplied URI directly to a filesystem path and stream the file, without confining it to the workspa...
In Eclipse Theia versions up to and including 1.73.1, the @theia/filesystem backend binds POST /file-upload in every filesystem-enabled deployment. The handler takes an attacker-supplied absolute path from the multipart uri field and calls fs.move(tmp, target, { overwrite: true }...
In Eclipse Theia versions 1.66.0 and up until including 1.73.1, the @theia/plugin-ext backend exposes the /hostedPlugin/:pluginId/:path(*) HTTP endpoint, which resolves the requested file path with path.resolve(localPath, filePath) without verifying that the resolved path stays w...
In Eclipse Theia versions 0.7.0 and up until including 1.73.1, the PreferenceUtils.merge function in @theia/core recursively merges preference values without rejecting prototype-related keys (__proto__, constructor, prototype). Because this function is invoked by PreferenceServic...
In Eclipse Theia versions prior to 1.69.0, custom task definitions in workspace files (e.g. .theia/tasks.json, .vscode/tasks.json) could be executed without requiring workspace trust. An attacker could craft a malicious repository that, when cloned and opened in Theia, leads to e...
In Eclipse Theia versions prior to 1.71.0, the AI chat rendered Markdown image tags from AI responses, triggering HTTP requests to arbitrary external URLs without restriction. Combined with prompt injection in a malicious workspace, an attacker could induce the AI agent to constr...
In Eclipse Theia versions prior to 1.71.0, files matching the pattern .prompts/*.prompttemplate in a workspace were automatically loaded and could override or extend the AI agent's system prompts. An attacker could craft a malicious repository containing prompt template files tha...
In Eclipse Theia versions prior to 1.71.0, the AI chat agent processed workspace file and directory names as part of its prompt context without distinguishing them from system instructions. An attacker could craft a malicious repository with adversarial directory or file names th...
In versions of the @theia/plugin-ext component of Eclipse Theia prior to 1.18.0, Webview contents can be hijacked via postMessage().
In Eclipse Theia 0.1.1 to 0.2.0, it is possible to exploit the default build to obtain remote code execution (and XXE) via the theia-xml-extension. This extension uses lsp4xml (recently renamed to LemMinX) in order to provide language support for XML. This is installed by default...
In Eclipse Theia 0.3.9 to 1.8.1, the "mini-browser" extension allows a user to preview HTML files in an iframe inside the IDE. But with the way it is made it is possible for a previewed HTML file to trigger an RCE. This exploit only happens if a user previews a malicious file..
In Eclipse Theia versions up to and including 0.16.0, in the notification messages there is no HTML escaping, so Javascript code can run.
In Eclipse Theia versions up to and including 1.8.0, in the debug console there is no HTML escaping, so arbitrary Javascript code can be injected.
In Eclipse Theia versions up to and including 1.2.0, the Markdown Preview (@theia/preview), can be exploited to execute arbitrary code.
In Eclipse Theia versions 0.3.9 through 0.15.0, one of the default pre-packaged Theia extensions is "Mini-Browser", published as "@theia/mini-browser" on npmjs.com. This extension, for its own needs, exposes a HTTP endpoint that allows to read the content of files on the host's f...
