{"id":"AZL-113107","summary":"CVE-2026-123535 affecting package python-tornado 6.3.3-11","details":"Tornado before 6.6 does not validate the max_age argument of RequestHandler.set_cookie (also called by set_signed_cookie, set_secure_cookie, and clear_cookie), allowing injection of additional Set-Cookie attributes. When an application passes attacker-influenced input as max_age, an attacker can embed attributes such as Domain, Path, or Secure to widen the cookie's scope to parent paths or other subdomains.","modified":"2026-11-11T14:17:31.770176974Z","published":"2026-11-08T02:16:43Z","upstream":["CVE-2026-123535"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-123535"}],"affected":[{"package":{"name":"python-tornado","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-tornado"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.3.3-11"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-113107.json"}}],"schema_version":"1.9.2"}
