2DescriptionCVE.org
A vulnerability was identified in a2ui-project a2ui up to 0.10.6. Affected is an unknown function of the file renderers/web_core/src/v0_9/basic_catalog/functions/safe_regex.ts of the component Basic Catalog. Such manipulation leads to inefficient regular expression complexity. The attack can be launched remotely.
AnalysisAI
Denial of service through catastrophic regular-expression backtracking affects the A2UI web_core and React renderer packages through version 0.10.6, where the Basic Catalog 'regex' function and TextField validation compile and execute attacker-supplied patterns without any safety check. An application that renders attacker-influenced A2UI schemas or expressions can have its JavaScript event loop pinned, freezing the UI or a headless renderer for an attacker-chosen duration at negligible cost to the attacker. …
