CVE-2026-72630
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
Incorrect Authorization in Kibana Fleet can lead to privilege escalation. Fleet restricts some callers to managing integration policies for one specific integration, but when updating a policy, the restriction is evaluated against the stored integration rather than the replacement integration.
Risk Assessment
The risk includes the ability to convert an endpoint policy into a policy for a different integration and supply its configuration, potentially leading to unauthorized system configuration changes.
Recommendation
Apply Kibana Fleet patches and verify privileges when updating integration policies.
Other vulnerabilities in Kibana Fleet
See all- CVE-2026-72632High
Observable Discrepancy in Kibana Fleet leads to information disclosure. Fleet removes the Elasticsearch API key value from agent listing responses, but accepts caller-supplied filters evaluated with Kibana's internal privileges, creating a side channel to reconstruct the full API key.
- CVE-2026-72631Medium
Improper Privilege Management (CWE-269) in Kibana Fleet can lead to privilege escalation via Privilege Escalation (CAPEC-233). An integration policy may optionally declare extra data streams that the integration writes to, which Fleet adds to the Elasticsearch API key issued to Elastic Agents enrolled in the corresponding agent policy. The resulting key allows new documents to be inserted and index mappings to be extended for specific indices. The key does not allow reading, updating, or deleting existing documents.
Original NVD description (English source)
Incorrect Authorization (CWE-863) in Kibana Fleet can lead to privilege escalation via Privilege Abuse (CAPEC-122). Fleet restricts some callers to managing integration policies for one specific integration. When an existing integration policy was updated, that restriction was evaluated against the integration recorded on the stored policy rather than against the replacement integration supplied with the update. An authenticated user holding only the Elastic Defend endpoint policy management privilege was therefore able to convert an endpoint policy they administer into a policy for a different integration, and to supply that integration's configuration at the same time.
