CVE-2026-59966

5.7 MEDIUM 0.3% exploit odds Fix listed Denial of service Web app

What it is

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.10, executes user-controlled Automation regular-expression patterns with Python re.sub() without complexity validation or an execution timeout when an authenticated user stores a catastrophic-backtracking regex and any user in the same Space imports a matching recipe. Request processing uses Automation.param_2, apply_regex_replace_automation, sub, api/recipe-from-source/. The attack works because the shared-Space automation engine evaluates the malicious pattern during recipe import and can occupy a Gunicorn worker until its request timeout. This can exhaust application worker slots and make the service unavailable to users. This issue is fixed in version 2.6.10.
