How severe is CVE-2026-30797?
CVE-2026-30797 is rated Critical with a CVSS score of 9.3. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Update to patched version when released
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
MITM can craft API messages to manipulate config/import actions without auth.
Patch when possible
- affected<= 1.4.5
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.
