What is VulGen'26 Workshop? The International Workshop on Vulnerabilities in Generative Systems for Information Retrieval (VulGen'26) brings together the IR community and related disciplines (e.g., cyber security) to foster cross-disciplinary engagement and advance understanding of vulnerabilities in generative systems used for IR. Through one-day structured discussion and engagement, we aim to (i) understand under what circumstances the generative systems could “go wrong” (i.e., vulnerabilities), in both current state and future development; and (ii) build a dedicated research community to address the potential downsides of generative systems that could lead to unexpected or harmful outcomes. We expect to build a dedicated research community to address the potential downsides of generative systems that could lead to unexpected or harmful outcomes.

What is the format of VulGen'26 Workshop? VulGen is an interactive, full-day workshop designed to foster deep collaboration. Expect a dynamic program packed with keynote and panel sessions, structured breakout discussions, statement presentations, and engaging poster and demonstration sessions.

Why VulGen'26 Workshop Matters? Generative systems are rapidly transforming both academic research and industrial practices. These systems are increasingly integrated into information access and IR tasks and continue to evolve at a substantial pace. Integrating these models into daily workflows exposes critical vulnerabilities, including adversarial attacks, inherent biases, and negative impacts on user behavior, which can lead to suboptimal or even detrimental outcomes.
