CVE-2026-92114 Details
Description
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.
A denial-of-service vulnerability has been identified in the A2UI project, specifically in versions through 0.10.6. The issue arises in the Basic Catalog component, where an unbounded agent-supplied regular expression is executed on the main thread of the client. This can lead to catastrophic backtracking, causing significant delays or even freezing the application. The vulnerability can be exploited remotely by sending a specially crafted regular expression that disrupts the application's performance.
The vulnerability has been addressed in a pull request that bounds the length of patterns and rejects unsafe ones. This fix is expected to be merged soon.
