MRMMIA: Membership Inference Attacks on Memory in Chat Agents
Membership inference attacks MIAs test whether a target data record belongs to a system's private data, and have become a standard tool to measure privacy leakage in machine learning systems. Prior work has primarily focused on training corpora or retrieval databases. However, MIAs against agent...
On Reliability of Efficient Membership Inference Vulnerability Evaluation
Membership inference attacks MIAs are popular methods for empirically assessing the leakage of sensitive information in the training data through models or statistics learned from the data. The MIA vulnerability is often evaluated through false positive rate FPR and true positive rate TPR of a...
AI Security Research Should Better Incentivize Defense Research
This work examines an imbalance in artificial intelligence AI security research: the field tends to produce more work on attacking AI systems than on defending them. Drawing on related academic papers, we find biased attack-to-defense ratios across subfields, including federated learning, speech...
Mattermost Server 11.5.x < 11.5.2 Missing Authorization (MMSA-2026-00645)
The version of Mattermost Server installed on the remote host is affected by a vulnerability as referenced in the MMSA-2026-00645 advisory. - Mattermost versions 11.5.x = 11.5.1 fail to verify channel membership when processing AI-assisted message rewrites which allows an authenticated attacker t...
Pretraining Data Exposure in Large Language Models: A Survey of Membership Inference, Data Contamination, and Security Implications
Large Language Models LLMs have become the predominant paradigm in NLP, advancing both research and industry. As model sizes and pretraining data grow, concerns about Pretraining Data Exposure PDE increase due to the scale and opacity of training datasets. PDE refers to determining whether specif...
corosync: Corosync: Denial of Service and information disclosure via crafted UDP packet
A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol UDP packet. This can lead to an out-of-bounds read, causing a denial of service...
