An authenticated user with cursor termination privileges on one database may be able to terminate active cursors on a different database due to improper scoping of authorization checks. This can disrupt ongoing query operations for other users. The issue arises from a privilege validation flaw that does not correctly restrict the termination capability to the intended database namespace.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13068) involves an authorization bypass where a user granted cursor termination privileges on one database can improperly terminate active cursors on another database. The root cause is an authorization check that fails to correctly scope privileges to the appropriate database namespace, allowing cross-database cursor termination. This can interrupt query operations for other users connected to the affected databases. The vulnerability is classified under CWE-863 (Incorrect Authorization).
Potential Impact
The impact is limited to disruption of active query operations on databases other than the one for which the user holds termination privileges. This could affect availability of database services for other users by prematurely terminating their active cursors. There is no indication of data disclosure or privilege escalation beyond cursor termination capabilities.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict cursor termination privileges carefully and monitor for unusual cursor termination activity. No official fix or patch links are currently provided.
