CVE-2026-33080
Filament: Unvalidated Range and Values summarizer values can be used for XSS
Description
Filament is a collection of full-stack components for accelerated Laravel development. Versions 4.0.0 through 4.8.4 and 5.0.0 through 5.3.4 have two Filament Table summarizers (Range, Values) that 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. This issue has been patched in versions 4.8.5 and 5.3.5.
