How to Fix CVE-2026-33080

To remediate this vulnerability, upgrade all affected Filament/tables dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

filament/tables fixed: 4.8.5 
Upgrade filament/tables to 4.8.5
filament/tables fixed: 5.3.5 
Upgrade filament/tables to 5.3.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for filament/tables

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-33080, inspect your project dependencies for Filament/tables:

inspect dependencies for filament/tables

Analyze the terminal output to locate any version of Filament/tables in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.8.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Filament/tables, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Two Table summarizers (`Range`, `Values`) render raw database values without escaping HTML. If there is a lack of validation for the data in the columns that use these summarizers, an attacker could plant malicious HTML / JavaScript and achieve stored XSS that executes for users who view the table with those summarizers.
