As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.

Fix and mitigation

WAF and other mitigations

Can a WAF block it? No. The attack is delivered via a crafted HTML page loaded in the browser, which looks like normal web content to a web application firewall and does not contain distinct malicious patterns that can be reliably filtered.

Also consider: patch

Based on an AI reading of the CVE description, and no vendor rule found yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.
