In July 1985 Michael O’Mara Books published its first book. At that time the firm’s only two employees were Mr. and Mrs. O’Mara and the offices were the spare bedroom of their semi-detached Clapham house, it was, quite literally, a Mom and Pop business. Now, after thirty years of publications, with a backlist of a thousand titles, it is still a family firm, producing one hundred and fifty new books a year. Succeeding as an independent in a publishing world dominated by vast, multinational conglomerates is not easy but it is fun.

Description

ThingsBoard in versions prior to v4.2.1 allows an authenticated user to upload malicious SVG images via the "Image Gallery", leading to a Stored Cross-Site Scripting (XSS) vulnerability. The exploit can be triggered when any user accesses the public API endpoint of the malicious SVG images, or if the malicious images are embedded in an `iframe` element, during a widget creation, deployed to any page of the platform (e.g., dashboards), and accessed during normal operations. The vulnerability resides in the `ImageController`, which fails to restrict the execution of JavaScript code when an image is loaded by the user's browser. This vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and allowing unauthorized actions.
