TidGi Desktop Remote Code Execution via Malicious TiddlyWiki Repository Import — Tiddler Startup Module Auto-Execution

Description

TidGi Desktop through 0.13.0 contains a critical remote code execution vulnerability exploitable via a single Git repository import. The vulnerability leverages TiddlyWiki's module system, which automatically discovers and executes JavaScript code embedded in .tid files placed in the wiki's tiddlers/ directory:

  1. Auto-loading of .tid files (src/services/wiki/wikiWorker/loadWikiTiddlersWithSubWikis.ts:59-92) — when TidGi boots a wiki workspace, loadWikiTiddlers reads all .tid files from the filesystem and adds them to the wiki store via wiki.addTiddlers().

  2. Automatic module registration (node_modules/tiddlywiki/boot/boot.js:2564-2565) — defineTiddlerModules() iterates all tiddlers in the store. Any tiddler with a module-type field is passed to $tw.modules.define(), registering it as an executable module.

  3. Automatic startup execution (node_modules/tiddlywiki/boot/boot.js:2572-2634) — all registered modules of type "startup" are collected and their exports.startup() function is called during the boot sequence. When no platforms restriction is set, doesTaskMatchPlatform() returns true, and the startup function executes with full Node.js require() access in the Wiki Worker process.

The full chain was verified on macOS with TiddlyWiki 5.4.0 and Node.js v26 — require('child_process').execSync() successfully executed arbitrary shell commands.

Affected Product

  • Product: TidGi Desktop
  • Vendor: Lin Onetwo (https://github.com/tiddly-gittly)
  • Repository: https://github.com/tiddly-gittly/TidGi-Desktop
  • Affected Versions: 0.13.0 (latest release)
  • Components: src/services/wiki/wikiWorker/loadWikiTiddlersWithSubWikis.ts (tiddler loading), src/services/wiki/wikiWorker/startNodeJSWiki.ts (wiki boot), node_modules/tiddlywiki/boot/boot.js (TiddlyWiki core — defineTiddlerModules, startup dispatch)
  • Package: tidgi (npm)

Vulnerability Details

Root Cause 1 — .tid Files Auto-Loaded Before Module Processing

File: src/services/wiki/wikiWorker/loadWikiTiddlersWithSubWikis.ts:59-92

const tiddlerFiles = wikiInstance.loadTiddlersFromPath(subWikiTiddlersPath);

for (const tiddlerFile of tiddlerFiles) {
    // Register file info for filesystem adaptor
    // ...
    // Add tiddlers to wiki
    wikiInstance.wiki.addTiddlers(tiddlerFile.tiddlers);   // ← Line 92
}

File: src/services/wiki/wikiWorker/startNodeJSWiki.ts:256

wikiInstance.boot.startup({ bootPath: TIDDLY_WIKI_BOOT_PATH });

This triggers $tw.boot.startup(), which internally calls loadStartup() → loadTiddlersNode() → $tw.loadWikiTiddlers($tw.boot.wikiPath) (boot.js:2381). TidGi overrides loadWikiTiddlers at startNodeJSWiki.ts:123 to intercept and inject sub-wiki tiddlers, but the original function still loads all .tid files from the main wiki's tiddlers/ directory.

Root Cause 2 — Automatic Module Registration via module-type Field

File: node_modules/tiddlywiki/boot/boot.js:1514-1534 — defineTiddlerModules()

$tw.Wiki.prototype.defineTiddlerModules = function() {
    this.each(function(tiddler,title) {
        if(tiddler.hasField("module-type") && (!tiddler.hasField("draft.of"))) {
            switch(tiddler.fields.type) {
                case "application/javascript":
                    $tw.modules.define(
                        tiddler.fields.title,           // "$:/plugins/poc/startup.js"
                        tiddler.fields["module-type"],   // "startup"
                        tiddler.fields.text              // attacker's JS code
                    );
                    break;
            }
        }
    });
};

This function is called during execStartup() (boot.js:2565), after loadStartup() has already loaded all .tid files into the wiki store. Any tiddler with module-type: startup and type: application/javascript is…
