CVE-2026-88410 Details
Description
The graph.UDF in FalkorDB (Redis module) v4.20.1 to v4.20.4 is not registered as a write command, leading to unexpected behavior within the application.
A vulnerability exists in the FalkorDB Redis module, specifically in versions 4.20.1 to 4.20.4, where the 'graph.UDF' command is not properly registered as a write command. This oversight leads to unexpected behavior, such as allowing unauthorized modifications to the application's state. Additionally, the issue includes a failure to handle errors correctly when loading user-defined functions from the database, and the absence of a mechanism to interrupt long-running JavaScript executions, which can cause the server to become unresponsive.
Users can update to FalkorDB version 4.20.3 or later, where this vulnerability has been fixed. Instructions for updating can be found in the FalkorDB documentation.
