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.
Affected products
| Product | Affected versions | Vendor says fixed in |
|---|---|---|
| Pivotal Pivotal Spring Data REST and Spring Boot | Pivotal Spring Data REST versions prior to 2.6.9 (Ingalls SR9), 3.0.1 (Kay SR1) and Spring Boot versions prior to 1.5.9, 2.0 M6Vendor says fixed in: not stated |
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? Partly. The bug can be reached over the network, so generic WAF rules may stop some attacks. Its weakness type is unknown, so we cannot be more precise.
Also consider: patch
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-2017-8046 being exploited?
Not confirmed. CVE-2017-8046 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 75% probability of exploitation in the next 30 days.
How severe is CVE-2017-8046?
CVE-2017-8046 is rated Critical with a CVSS score of 9.8. 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-2017-8046?
Yes. A fix has been recorded for CVE-2017-8046. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2017-8046 affect?
CVE-2017-8046 affects vmware:spring_boot, pivotal_software:spring_data_rest, vmware:spring_data_rest. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
