CVE-2026-35046
Prior to 2.6.4, Tandoor Recipes allows authenticated users to inject arbitrary <style> tags into recipe step instructions.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, Tandoor Recipes allows authenticated users to inject arbitrary <style> tags into recipe step instructions. The bleach.clean() sanitizer explicitly whitelists the <style> tag, causing the backend to persist and serve unsanitized CSS payloads via the API. Any client consuming instructions_markdown from the API and rendering it as HTML without additional sanitization will execute attacker-controlled CSS — enabling UI redressing, phishing overlays, visual defacement, and CSS-based data exfiltration. This vulnerability is fixed in 2.6.4.
