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."}],"source":{"advisory":"GHSA-f2gw-c2c7-59v7","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/TandoorRecipes/recipes/security/advisories/GHSA-f2gw-c2c7-59v7","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-16T19:39:45.918792Z","id":"CVE-2026-59966","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T19:40:13.402Z"}}]}}
