The best Vulnerability Research newsletters

Technical deep-dives into newly disclosed and actively exploited vulnerabilities in enterprise software such as PaperCut, Atlassian products and Citrix NetScaler. Posts cover affected products, root-cause analysis, exploit chains and patch bypasses, written with a sarcastic voice.

The PRIDE Security Blog publishes offensive security research, including write-ups of a Microsoft Defender Automatic Attack Disruption bypass, a CVE-2024-29417 local privilege escalation in an E-TRUST identity system, and a multi-part series on attacking physical turnstiles. Readers get technical details, affected components, prerequisites and mitigation context for each finding.

Weekly cybersecurity newsletter from Sentry covering offensive and defensive security tools and research, including a prompt-injection workbench, a study of abusing free inference, and a disclosed Apple Private Cloud Compute vulnerability. Readers get practical tooling walkthroughs and technical write-ups from applied AI security research.

Research-driven posts on offensive cybersecurity and geopolitical cyber and technology issues, including AI's effect on the exploit market and Russian-Iranian cooperation on drones and cyber capabilities. Readers get original analysis built on open-source information and industry expertise.

Technical security blog from isec.pl covering vulnerability research, such as ZIP path traversal tricks, and Android Keystore and biometric protection analysis, with some articles in Polish. Readers get detailed attack-surface walkthroughs and practical security reasoning from a pentesting perspective.

A security practitioner's newsletter with short essays on bug bounty triage, AI's effect on vulnerability research, and the economics of security. It mixes conference reflections, recommendations for industry change, and excerpts from podcast conversations.

A weekly-ish digest for exploit developers and vulnerability researchers, curating and summarising recent write-ups on topics like LLM-driven exploit generation, QEMU bugs, Pwn2Own exploits and Android kernel research. It also flags upcoming conferences, CTFs and community events.

A personal infosec notebook by a security researcher, mainly pointing to their articles on Windows privilege escalation, cross-user execution, and bring-your-own-vulnerable-driver (BYOVD) attacks. Excerpts are short announcements linking to PDFs, so the substance lives in the linked research rather than the newsletter itself.
