Vulnerabilities are flaws attackers can exploit to access systems or data; timely patching, isolation, and least privilege reduce the impact.

Background for this topic.
A vulnerability is a weakness in a system’s design, code, configuration, or operating process that could allow an attacker to violate a security requirement. It may affect software, hardware, networks, cloud services, or exposed interfaces, and is not automatically exploitable: practical risk depends on factors such as exposure, required privileges, available attack paths, and existing controls. Outcomes can include unauthorized access, information disclosure, code execution, or disruption of service.
Effective vulnerability management combines accurate asset inventory with code review, security testing, scanning, and trusted vulnerability intelligence. Organizations should prioritize weaknesses affecting reachable, business-critical systems—especially when exploitation is known or requires little access—then patch or otherwise mitigate them and verify the fix. Where patching is delayed, controls such as disabling an exposed feature, restricting network access, or strengthening authentication can reduce the attack surface. Records should preserve affected versions, risk decisions, remediation owners, and validation results.
A newly discovered local privilege escalation vulnerability dubbed 'CIFSwitch' in the Linux kernel could allow attackers to forge CIFS authentication key descriptions, abuse the kernel's key request mechanism, and gain root privileges. [...]
Palo Alto Networks has warned that a recently disclosed medium-severity security flaw impacting PAN-OS and Prisma Access has come under active exploitation in the wild
Severity and Reachability Metrics Also Essential for Mythos-Era Bug MitigationIf there's one thing artificial intelligence has done, it's multiply bugs, and the annual CVE Program count of new vulnerabilities is set to break records. Less apparent is how many of those AI-ferreted vulnerabilities can be turned into high-impact exploit chains - if they're exploitable at all.
Cybersecurity researchers have disclosed details of a vulnerability in OpenAI ChatGPT that leverages the artificial intelligence (AI) assistant's implicit trust in Markdown links and images to trigger prompt injections and open the door to phishing attacks
An unknown threat actor has been observed using a large language model (LLM) agent to conduct post-compromise actions after obtaining initial access following the exploitation of a publicly-accessible Marimo network using a recently disclosed vulnerability
A researcher dropped 6 Windows zero-days with no warning. Three are now exploited in the wild. Microsoft is angry. The researcher says Microsoft ignored them first. Over the past month, a researcher going by Chaotic Eclipse, also known as Nightmare-Eclipse, publicly released details of six unpatched vulnerabilities in Windows components including Defender and BitLocker. No […]
Security Researchers Fear Broader Legal Pressure on Bug DisclosuresMicrosoft is pursuing legal action after a researcher publicly released six Windows zero-days and exploit code following a breakdown in coordinated disclosure talks, escalating tensions over vulnerability disclosure, platform moderation and protections for independent security researchers.
Hackers are exploiting an authentication bypass vulnerability (CVE-2026-35616) in FortiClient Enterprise Management Server (EMS) to deliver an undocumented credential stealer called EKZ. [...]
A critical security vulnerability has been disclosed in Gogs, a popular open-source self-hosted Git service, that allows an authenticated user to execute arbitrary code under certain conditions
Threat actors are exploiting a critical FortiClient EMS flaw, tracked as CVE-2026-35616, to deploy malware on unpatched systems. Threat actors are exploiting a critical FortiClient EMS vulnerability, tracked as CVE-2026-35616 (CVSS score of 9.1), that allows remote code execution without authentication. Fortinet released fixes in April after confirming zero-day attacks in the wild and urged […]
An unpatched zero-day vulnerability in the Gogs self-hosted Git service can allow attackers to gain remote code execution (RCE) on Internet-facing instances. [...]
Microsoft has come out strongly in favor of Coordinated Vulnerability Disclosure (CVD), urging the research community to share their findings and give affected vendors an opportunity to better understand the impact and address them before they are publicly disclosed
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Daemon Tools, TanStack, and Nx Console flaws to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added Windows Shell and ConnectWise ScreenConnect flaws to its Known Exploited Vulnerabilities (KEV) catalog. Below are the flaws added to the catalog: The first flaw, tracked as CVE-2026-8398, […]
Microsoft warned the disclosure of several unpatched vulnerabilities without notice has put “customers at unnecessary risk”
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds LiteSpeed cPanel Plugin flaw to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the LiteSpeed cPanel Plugin flaw CVE-2026-48172 to its Known Exploited Vulnerabilities (KEV) catalog. CVE-2026-48172 (CVSS score of 10.0) affects the LiteSpeed User-End cPanel plugin before version 2.4.5 and allows […]
Cybersecurity researchers have disclosed a security flaw in Gitea, an open-source, self-hosted platform for version control, that allows unauthenticated remote attackers to pull private container images from Gitea deployments without requiring an account, password, or other credentials
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has given U.S. federal agencies four days to secure their servers against a critical vulnerability in the LiteSpeed cPanel user-end plugin, which is actively being exploited in attacks. [...]
A critical vulnerability, tracked as CVE-2026-45659, in Microsoft SharePoint can allow attackers to achieve remote code execution with little effort. Microsoft released security updates to patch a high-severity SharePoint vulnerability, tracked as CVE-2026-45659 (CVSS score of 8.8), that could allow remote code execution. The flaw does not require complex conditions for exploitation, making it a […]
Expect to See Widespread Availability of Mythos-Level Models Within 6-12 MonthsAnthropic is expanding public access to its frontier artificial intelligence model Claude Mythos "to qualifying customers' security teams on request" for such purposes as vulnerability research and red-teaming, and predicts that Mythos-class models will be publicly available within 12 months.
