8.8 · HIGHOverview
CVE-2026-29089 is a high-severity vulnerability affecting timescale timescaledb. It was published on March 6, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
TimescaleDB is a time-series database for high-performance real-time analytics packaged as a Postgres extension. From version 2.23.0 to 2.25.1, PostgreSQL uses the search_path setting to locate unqualified database objects (tables, functions, operators). If the search_path includes user-writable schemas a malicious user can create functions in that schema that shadow builtin postgres functions and will be called instead of the postgres functions leading to arbitrary code execution during extension upgrade. This issue has been patched in version 2.25.2.
Remediation
Check the references section for vendor advisories and patches from timescale. Update timescaledb to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
