Potential Impact
The denial of service vulnerability (CVE-2026-31958) could allow an attacker to disrupt service availability by sending large multipart bodies to the Tornado server. The cookie attribute injection vulnerability (CVE-2026-35536) could lead to improper cookie handling, potentially affecting session management or security controls relying on cookies. Both vulnerabilities have been rated as moderate in severity by Red Hat Product Security. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated python-tornado packages that fix these vulnerabilities. Users of Red Hat Enterprise Linux 10 and related extended support versions should apply the security update as described in Red Hat advisory RHSA-2026:19034. Detailed instructions for applying the update are available at https://access.redhat.com/articles/11258. Since this is a traditional software package, remediation requires applying the vendor-provided patch. No additional mitigations or workarounds are indicated in the advisory.
