Summary
Triage
The summary, impact and action text on this page are written by our AI analysis pipeline, or taken from the NVD description when a CVE was imported from NVD. They are not the vendor's wording: check them against the sources. A longer AI executive summary and technical analysis are generated for signed-in accounts on the Max plan.

Fix and mitigation
WAF and other mitigations
Can a WAF block it? Partly. Code injection payloads are often obfuscated, so they slip past generic WAF rules.
Also consider: remove eval sinks · RASP
Based on the weakness type only; no CVE-specific evidence yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Common questions
Is CVE-2023-46818 being exploited?
Not confirmed. CVE-2023-46818 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 19% probability of exploitation in the next 30 days.
How severe is CVE-2023-46818?
CVE-2023-46818 is rated High with a CVSS score of 7.2. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2023-46818?
Yes. A fix has been recorded for CVE-2023-46818. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
