Elk: Authorization Bypass Through User-Controlled Key in Kibana Leading to Information Disclosure (CVE-2026-72650)
CVE-2026-72650 is an authorization bypass vulnerability in Kibana that allows an authenticated user with read access to alerting rules in one space to access alerting rule execution telemetry from other spaces they are not authorized to view. The disclosed information includes rule identifiers, names, space identifiers, execution outcomes, timestamps, and counters. This vulnerability affects Kibana versions 8.0.0 up to but not including 8.19.20, and 9.0.0 up to but not including 9.4.5. A patch is available to address this issue. No known exploits are reported in the wild. The severity is assessed as medium based on the impact of unauthorized information disclosure.
AI Analysis
Technical Summary
CVE-2026-72650 is an authorization bypass vulnerability in Kibana caused by improper access control on alerting rule execution telemetry. An authenticated user authorized to read alerting rules in a single Kibana space can exploit this flaw to retrieve telemetry data from other spaces without proper authorization. The leaked telemetry includes sensitive metadata such as rule IDs, names, space IDs, execution outcomes, timestamps, and counters. This issue affects Kibana versions >=8.0.0 <8.19.20 and >=9.0.0 <9.4.5. A patch is available to fix this vulnerability. There are no reports of active exploitation in the wild.
Potential Impact
An attacker with authenticated read access to alerting rules in one Kibana space can access alerting rule execution telemetry from other spaces they are not authorized to access. This leads to unauthorized information disclosure of telemetry data including rule identifiers, names, space identifiers, execution outcomes, timestamps, and execution counters. While this does not allow direct control or modification, it exposes potentially sensitive operational data across spaces.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade Kibana to versions 8.19.20 or later, or 9.4.5 or later, where this authorization bypass issue is fixed. There are no indications that additional mitigations are required beyond applying the official fix.
