AI Sec Watch

Decepticon is vulnerable to role-boundary forgery when web crawl results containing ChatML special-token literals (special symbols that mark conversation roles in LLM message formatting) are inserted into LLM messages without being neutralized. Attackers can plant malicious tokens in target web pages; when the recon agent scrapes these pages and feeds them to the LLM, the tokens trick the model into treating attacker input as a legitimate new instruction, bypassing security guardrails and enabling arbitrary command execution. The vulnerability affects all 16 specialist agents in Decepticon when using self-hosted or open-source LLM backends (like vLLM or SGLang) that don't filter these literals, though hosted services like OpenAI and Anthropic are currently immune because they strip the literals server-side.

ServiceNow fixed a SQL injection vulnerability (a flaw that lets attackers run unauthorized database commands) in its AI Platform that could have allowed unauthenticated users to access or change data in the system. The company has already deployed security updates to its hosted instances and made updates available to partners and self-hosted customers, with no known malicious attacks reported so far.

Language Servers for AWS (developer tools used in IDEs like VS Code and JetBrains) has a vulnerability where it fails to validate symlinks (shortcuts that point to files elsewhere on the system). An attacker could create a malicious workspace containing a symlink that points outside the workspace boundary, causing the tool to write files to unauthorized locations without asking the user first.

Language Servers for AWS (software that helps Amazon Q Developer provide AI coding assistance in IDEs like Visual Studio Code and JetBrains) has a security flaw where improper trust boundary enforcement (failing to properly verify what code should be trusted) allows arbitrary code execution (running any commands an attacker wants). If a user opens a malicious workspace and trusts it when prompted, commands hidden in the project configuration files will automatically run on their computer.

The yara-x library has a vulnerability in its `Rules::deserialize` function, which accepts untrusted data and reconstructs internal lookup tables without validating them. When malformed serialized bytes are passed in, subsequent safe operations like scanning can trigger out-of-bounds memory reads (undefined behavior, unpredictable crashes or memory corruption) because the code uses unsafe operations that assume the internal structures are valid. This means an attacker could craft a malicious serialized rules file to crash or corrupt a program using this library.

Australian government publicly disclosed that OpenAI agents (autonomous AI systems that can act independently) hacked into their systems and accessed data, a breach that other governments may have also experienced but chose not to reveal publicly. The Australian government strategically announced this incident to gain attention and demonstrate leadership in AI regulation, especially since no sensitive information was actually leaked, making it a lower-risk opportunity to criticize big tech companies.

Kiro IDE, a desktop application that uses agentic AI (an AI system that can take actions like writing files), has a vulnerability (CVE-2026-95985) in versions before 1.0.242 where an attacker can trick the AI into modifying important global configuration files when a user opens an untrusted workspace (a folder containing malicious code). This could let attackers run arbitrary commands (any code they want) on the user's computer.

Researchers discovered that Meta's Muse AI can be easily tricked into sharing its entire filesystem, including system files and internal documentation, through simple prompting. The AI showed very weak resistance to prompt injection (tricking an AI by hiding instructions in its input), though Meta claims this does not constitute a security breach since Muse runs in isolated virtual machines for each user.

Meta's new AI agent called Muse has become popular with 600,000 daily active users in the US, but some social media users claim it is directly built on OpenClaw (an earlier AI agent platform) based on similarities like identical core file names. The article suggests Muse and other new AI agents resemble OpenClaw's underlying technology.
