Quercus is a young, vibrant, internationally successful and award-winning publisher of fiction, non-fiction and children’s books. Quercus was established by Mark Smith and Wayne Davies in May 2004. The Directors had previously worked together at the Orion Publishing Group. Starting out in a small office in Dorset Street, London, the company quickly expanded, producing best sellers with each of its first two titles, Universe and Speeches that Changed the World. These titles have now generated sales of approximately 250,000 and 800,000 copies respectively, and both continue to sell strongly around the world. In July 2006 Quercus made its debut appearance on the UK bestseller lists with Peter Temple’s The Broken Shore, and by October the company had been listed on Plus Markets, attracting new levels of investment and ensuring a strong financial platform for future development. 2007 began with our first major literary prize, for Stef Penney’s The Tenderness of Wolves. It not only won the Costa Best First Novel Award, but was ultimately named as victor in the overall Book of the Year category. We were also pleased to be unveiled as one of three finalists at the Fast Growth Business Awards 2007, in the ‘PLUS New Company of the Year’ category. In 2008, under our MacLehose Press imprint, we published Stieg Larsson’s The Girl with the Dragon Tattoo, which won a Galaxy British Book Award. In 2009 the book’s sequel, The Girl Who Played with Fire, became the company’s first number one bestseller. It was the first translated title to top the UK hardback fiction chart – a landmark in British publishing history.

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.
