Language Model Security Database

Large Language Model (LLM)-integrated web applications using Langchain (and potentially similar middleware) are vulnerable to Prompt-to-SQL (P2SQL) injection attacks. Unsanitized user prompts can be crafted to cause the LLM to generate malicious SQL queries, leading to unauthorized database access (read and write operations). This vulnerability bypasses attempts to restrict the LLM through prompt engineering alone.

A vulnerability in vision-integrated Large Language Models (VLMs) allows an attacker to circumvent safety mechanisms through the use of adversarially crafted visual examples. A single, carefully constructed image can universally "jailbreak" the model, causing it to generate harmful content in response to a wide range of subsequent prompts, even those not included in the adversarial example's training data. This vulnerability extends beyond simple misclassification to encompass the execution of…

A prompt injection vulnerability allows attackers to manipulate the behavior of Large Language Model (LLM)-integrated applications by crafting malicious prompts that override the application's intended functionality. Attackers can achieve this by constructing prompts that cause the LLM to interpret malicious payloads as instructions, rather than data, leading to unintended actions such as data leakage, unauthorized LLM usage, or application mimicry. This vulnerability exploits the way user…
