HiTMS: A High-Throughput Multi-Stream Linguistic Steganography Framework Research code for linguistic steganography over LLM chat dialogues , with a single-stream baseline and a batched multi-stream HiTMS protocol that hides several independent secret messages at once and exploits GPU batching fo...

The Model Plants the Trigger: Answer-Side Backdoor Attacks in Multi-Turn Large Language Models

Safety alignment in Large Language Models LLMs remains vulnerable to backdoor attacks. Existing LLM backdoors are almost all input-centric: activation depends on explicit trigger patterns in the user input, so modern guardrails are built to sanitize the input space. We challenge this assumption...

CLEANSTART-2024-UR50012 Use after free in Window Dialogue in Google Chrome prior to 98

Security vulnerability affects the chromium package. Use after free in Window Dialogue in Google Chrome prior to 98...

Does the Unsafe Gradient Survive a Conversation? on the Fragility of Gradient-Based Jailbreak Detection in Multi-Turn Dialogue

Safety-aligned language models are commonly deployed as multi-turn assistants, which lets adversaries spread unsafe intent across several user turns instead of a single prompt. Gradient-based jailbreak detectors such as GradSafe were developed for single prompts: they score an input by the...

Astra Linux – Vulnerability in Chromium

The use of "after free" in Window Dialogs in Google Chrome before version 98.0.4758.80 allowed a remote attacker to potentially exploit heap corruption through a crafted HTML page...

HiTMS: A High-Throughput Multi-Stream Linguistic Steganography Framework

Research code for linguistic steganography over LLM chat dialogues, with a single-stream baseline and a batched multi-stream HiTMS protocol that hides several independent secret messages at once and exploits GPU batching for much higher throughput. A Bob model asks questions; an Alice model...

OpenClaw input validation error vulnerability (CNVD-2026-26890)

OpenClaw is an intelligent artificial assistant open-sourced by the OpenClaw team. OpenClaw has a vulnerability related to input validation. An attacker can exploit this vulnerability to match allowed list entries based on dialogue metadata rather than a stable sender identity. This allows them t...

Hijacking Agent Memory: Stealthy Trojan Attacks through Conversational Interaction

Large language model LLM agents increasingly leverage long term memory to support persistent and autonomous task execution. However, this capability also introduces a new attack surface: memory poisoning, where adversaries can inject malicious information to influence future behavior. Existing...

CVE-2026-7845

The CVE-2026-7845 issue affects chatchat-space Langchain-Chatchat (up to 0.3.1.3). It targets the Vision Chat Paste Image Handler: the function PIL.Image.tobytes in libs/chatchat-server/chatchat/webui_pages/dialogue/dialogue.py, via manipulation of paste_image.image_data, leads to the use of a we...

ContextualJailbreak: Evolutionary Red-Teaming Via Simulated Conversational Priming

Large language models LLMs remain vulnerable to jailbreak attacks that bypass safety alignment and elicit harmful responses. A growing body of work shows that contextual priming, where earlier turns covertly bias later replies, constitutes a powerful attack surface, with hand-crafted multi-turn...
