CVE-2026-118537 Details
Description
A vulnerability was found in a2ui up to 0.10.4. This vulnerability affects unknown code of the file src/v0_9/basic_catalog/components/Image.js of the component Image Player/Video Player/Audio Player. Performing a manipulation of the argument url results in improper input validation. The attack may be initiated remotely. The pull request to fix this issue awaits acceptance.
A vulnerability exists in a2ui versions through 0.10.4, specifically within the media components of the web_core package. The issue arises in the Image, Video, and AudioPlayer components, which improperly validate the 'url' prop before binding it to the 'src' attribute of media elements. This lack of validation allows for remote manipulation of the 'url' argument, potentially leading to server-side request forgery (SSRF) by causing the victim's browser to make credential-bearing requests to attacker-chosen or internal URLs. The vulnerability has been addressed in a pull request that is currently awaiting review.
Users can update to a2ui version 0.10.5 or later, where this vulnerability has been fixed.
