Selective Channel Restoration for Backdoored Vision-Language Models
Vision-language models VLMs exhibit strong multimodal capabilities but remain vulnerable to backdoors implanted through poisoned fine-tuning data. Existing defenses often require extensive parameter updates during fine-tuning or incur per-query overhead during inference. To address these...
A Competing-Hazards Systematization of Loss of Control in Autonomous Agents
Leading AI developers have reported agents acting beyond their approved limits, which a United Nations panel described as an early warning of loss of human control. Yet incident reports and agent-safety evaluations describe these events differently, making it difficult to compare failures, trace...
The Geometry of Harmfulness in Multi-Turn Attacks
Large language models LLMs remain vulnerable to adversarial attacks that circumvent safety alignment to elicit harmful outputs. It remains unclear how harmfulness and refusal representations evolve over the course of multi-turn attacks, and why single-turn defenses are less effective in multi-tur...
Where Do LLMs Decide to Break the Rules? Mechanistic Localization of Prompt Injection Compliance
When a prompt injection attack succeeds, a Large Language Model LLM abandons its assigned system role to comply with an adversarial instruction. While prior work has extensively quantified how often this occurs, we ask a more fundamental question: where inside the network does the model actually...
ModalFidelity: Routing Modalities for Deepfake Detection on a Budget
Deepfakes no longer need to fake a whole video. Generators that read the transcript now alter only the few seconds in which a video's meaning turns, so a forgery hides in a small, unknown fraction of the video. Yet detectors still read every one-second window of both the audio and image streams,...
FreeBSD Security Advisory - FreeBSD-SA-26:68.openssl
FreeBSD Security Advisory - Out-of-bounds read in OpenSSL DTLS retransmission. The retransmitted message may include heap memory contents, disclosing them to the DTLS peer as plaintext handshake data. If the read reaches unmapped memory, the application crashes, resulting in a Denial of Service D...
Privacy in Personalized AI Is a System Property, Not Just a Model Property
In personalized AI applications, such as conversational assistants and recommender systems, users interact not with models in isolation but with broader systems that access, infer, and reuse user information across components and over time. While such use of user information is integral to...

A Function-Level Dataset of Vulnerable and Fixed Source Code in JavaScript and TypeScript
JavaScript and TypeScript are widely used in modern web development, making their security critical; however, automated vulnerability detection is often constrained by the availability of high-quality training data. Here we present JsVul, a dataset curated from seven major sources. Unlike generic...
Confidence-Guided Protocol IR for LLM-Aided Security Protocol Modeling
Large language models offer a promising interface for translating natural-language protocol descriptions into formal security models, but their outputs remain difficult to trust without expert validation. In this paper, we present a human-in-the-loop framework for generating Tamarin-verifiable...
Quantum Time-Lock Puzzles in the Quantum Random Oracle Model
A time-lock puzzle allows a sender to hide a message in a puzzle such that recovering the message requires substantially more sequential computation than the time required to generate the puzzle, even when parallel computation is allowed. Applications of time-lock puzzles include timed-release...
Controlled Decoding Attacks on Black-Box LLMs
Manipulating next-token probabilities during generation can bypass the safety alignment of large language models. Existing approaches, however, rely on access to model weights or numerical token probabilities and therefore do not apply to interfaces that return only sampled text. Reconstructing...
One Pipeline Does Not Fit All: TAILOR, a Type- and State-Aware Framework for CVE Reproduction
Growing vulnerability disclosure and widespread software reuse increase security teams' need for reproducible evidence to diagnose vulnerabilities, validate patches, and build regression tests. Producing such evidence at scale requires automated end-to-end CVE reproduction. Existing methods...

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...
CollageAttack: Exploiting Cross-Modal Alignment Flaws in T2I Models through Spatial Text Composition
Text-to-image T2I models have substantially improved in language understanding, in-image text rendering, and visual composition, while their safety mechanisms do not always keep pace with these capabilities. This creates a cross-modal attack surface in which harmful semantics can remain...
Removing the NEEDLE in the Haystack: Backdoor Removal in LLMs Via Weight Orthogonalisation
Backdoor attacks can be implanted in Large Language Models LLMs during training, causing unwanted behaviour when a trigger appears in the input. Existing backdoor defences for LLMs attempt to remove the backdoor but inadvertently shift the model's output distribution to benign prompts, which can...

When Cyber Scoring Systems Diverge: An Empirical Comparison
Vulnerability scoring systems underpin cyber patch prioritization and risk management, but their comparative behavior is almost always assessed in the abstract, through correlation studies in IT vulnerability databases, rather than by the operational consequences they produce when embedded in a...
Behavior-Centric Malware Classification with Fine-Grained Malicious Logic Localization
Effective malware analysis requires understanding not only whether a program is malicious, but also which behaviors it exhibits and where those behaviors originate in the code. Existing machine-learning-based malware detectors largely operate as black boxes, providing limited insight into the...

Pikit: A Composable Toolkit for Indirect Prompt Injection Research and Evaluation
Indirect prompt injection embeds malicious instructions within external content retrieved by LLM-based agents, altering target behavior without user authorization. We introduce pikit, a research toolkit designed to systematically evaluate these threats across three core dimensions: attacks 13...
ToolFence: Fine-Grained Authorization for Secure Tool-Using LLM Agents
Tool-using LLM agents remain vulnerable to indirect prompt injection because trusted instructions and untrusted observations share one context, allowing malicious content to steer consequential input-filtering defenses. Multi-path consensus defenses still leave a high attack success rate because...

Proof-Gated Signing: Solver-Checked Transaction Guards That Hold under State Drift for Onchain AI Agents
AI agents that control wallets read attacker-reachable content, so they can be steered into proposing harmful transactions. The usual last line of defense is a pre-signing check: a static allowlist, an LLM reviewer, or a transaction simulation. All three share a gap: the check describes the chain...
SiYuan 3.8.3 MCP File Operations Path Traversal
SiYuan versions 3.8.0 through 3.8.3 contain an incorrect authorization issue in recursive MCP file operations. An authenticated administrator can bypass the sensitive-path guard to read protected descendants or overwrite them through archive extraction...
Backdoor Mitigation in Decentralized LLM Fine-Tuning
Decentralized large language model LLM fine-tuning lets organizations collaboratively train a shared LLM on data they cannot pool, without a central coordinator. In every round, each node exchanges a trainable adapter with its neighbors over a communication graph, and then aggregates them. This...
Security-Enhanced Seed-Based Weight Quantization for Large Language Models
Large language models LLMs incur substantial storage, memory-bandwidth and energy costs, motivating compact weight representations. Existing seed-based compression methods reconstruct weights from compact pseudo-random representations but do not explicitly account for the non-uniform sensitivity ...
OpenSSL Security Advisory 20260929
OpenSSL Security Advisory 20260929 - The DTLS retransmission logic does not correctly handle a handshake message write that is suspended part-way through. The retransmitted message can be read past the message buffer and the retransmission overwrites the internal state the suspended write needs t...
