AI Sec Watch

OpenCode is an open source AI coding agent that, before version 1.0.216, automatically started an unauthenticated HTTP server (a service that accepts web requests without requiring a password or login). This allowed any local process or website with permissive CORS (a web setting that controls which websites can access a server) to execute arbitrary shell commands with the user's privileges, meaning someone could run malicious commands on the affected computer.

MLFlow versions up to 3.4.0 have a vulnerability where the REST server (the interface that external programs use to communicate with MLFlow) doesn't properly validate Origin headers, which are security checks that prevent unauthorized websites from making requests. This allows attackers to use DNS rebinding attacks (tricks where malicious websites disguise their identity to bypass security protections) to query, modify, or delete experiments, potentially stealing or destroying data.

Unlearnable examples are protective noises added to private data to prevent AI models from learning useful information from them, but this paper shows that data augmentation (a common technique that creates variations of training data to improve model performance) can undo this protection and restore learnability from 21.3% to 66.1% accuracy. The researchers propose Armor, a defense framework that adds protective noise while accounting for data augmentation effects, using a surrogate model (a practice model used to simulate the real training process) and smart augmentation selection to keep private data unlearnable even after augmentation is applied.

vLLM is a serving engine for running large language models, and versions 0.6.4 through 0.11.x have a vulnerability where attackers can crash the server by sending a tiny 1x1 pixel image to models using the Idefics3 vision component, causing a dimension mismatch (a size incompatibility between data structures) that terminates the entire service.

The BetterDocs plugin for WordPress (all versions up to 4.3.3) has a vulnerability that exposes sensitive information, allowing authenticated attackers with contributor-level access or higher to extract data including OpenAI API keys stored in the plugin settings through the scripts() function. This affects any WordPress site using the plugin where users have contributor-level permissions or above.

LibreChat version 0.8.1-rc2 has a server-side request forgery vulnerability (SSRF, where an attacker tricks a server into making requests to unintended targets) because the Actions feature allows agents to access any remote service without restrictions, including internal components like the RAG API (retrieval-augmented generation system that pulls in external documents). This means attackers could potentially use LibreChat to access internal systems they shouldn't reach.

LibreChat version 0.8.1-rc2 has an access control vulnerability where authenticated attackers (users who have logged in) can read permissions of any agent (a predefined AI assistant with specific instructions) without proper authorization, even if they shouldn't have access to that agent. If an attacker knows an agent's ID number, they can view permissions that other users have been granted for that agent.

LibreChat version 0.8.1-rc2 has a missing authorization (a failure to check if a user has permission to do something) vulnerability that allows an authenticated attacker to upload files to any agent's file storage if they know the agent's ID, even without proper permissions. This could let attackers change how agents behave by adding malicious files.

A WordPress plugin called 'Tag, Category, and Taxonomy Manager – AI Autotagger with OpenAI' has a security flaw (CWE-862, missing authorization) in versions up to 3.41.0 that allows contributors and higher-level users to add or remove taxonomy terms (tags and categories) on any post, even ones they don't own, due to missing permission checks. This vulnerability affects authenticated users who have contributor-level access or above.
