In versions prior to 0.11.16, EPUB chapter HTML is sanitized with DOMPurify using a configuration that forbade only the &lt;script&gt; tag (FORBID_TAGS: [&#39;script&#39;]) in apps/readest-app/src/services/transformers/sanitizer.ts. DOMPurify does not parse the contents of the srcdoc attribute on &lt;iframe&gt; elements, treating it as an opaque string attribute, so an attacker who can get an &lt;iframe&gt; element to survive sanitization can embed a complete HTML document containing a &lt;script&gt; tag inside srcdoc and have it execute when the browser renders the iframe. The content iframe is configured with sandbox=&#34;allow-same-origin allow-scripts&#34;, so script executing inside it shares the parent origin and can reach parent.parent.__TAURI_INTERNALS__.invoke(...), giving access to every Tauri IPC command the application is permitted to use, which escalates to arbitrary code execution. The payload can be made invisible (zero-size, transparent iframe) so the reader sees only normal book text. Version 0.11.16 hardened the sanitizer configuration by adding &#39;iframe&#39;, &#39;object&#39; and &#39;embed&#39; to FORBID_TAGS and adding &#39;srcdoc&#39; to FORBID_ATTR.</p> <p>Readest is an open-source e-book reader built on Tauri.
