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.
Fears over chained attacks affecting EOL product The US Cybersecurity and Infrastructure Security Agency (CISA) just added the latest Ivanti weakness to its Known Exploited Vulnerability (KEV) catalog, a situation sure to annoy some – given that it's yet another path traversal flaw.…
A new report by Check Point Software highlights a significant increase in cloud security incidents, largely due to a lack of cybersecurity expertise and employee training
Ivanti has revealed that a critical security flaw impacting Cloud Service Appliance (CSA) has come under active exploitation in the wild
Write better code, urges Jen Easterly. And while you're at it, give crime gangs horrible names like 'Evil Ferret' Software suppliers who ship buggy, insecure code need to stop enabling cyber criminals who exploit those vulnerabilities to rob victims, Jen Easterly, boss of the US government's Cybersecurity and Infrastructure Security Agency, has argued.…
Chinese Botnet Targets US Critical Infrastructure and TaiwanA Chinese state-sponsored botnet called Raptor Train has infected more than 260,000 IoT and office network devices to target critical infrastructure globally. The hackers used zero-days and known vulnerabilities to compromise more than 20 different types of devices to expand their botnet.
The U.S. Cybersecurity and Infrastructure Agency (CISA) has added five flaws to its Known Exploited Vulnerabilities (KEV) catalog, among which is a remote code execution (RCE) flaw impacting Apache HugeGraph-Server. [...]
The first patch lets threat actors with low-level credentials still exploit the vulnerability, while the second fully resolves the flaw.
A clever threat campaign is abusing GitHub repositories to distribute malware targeting users who frequent an open source project repository or are subscribed to email notifications from it. A malicious GitHub user opens a new "issue" on an open source repository falsely claiming that the project contains a "security vulnerability." [...]
Cybersecurity in healthcare has never been more urgent. As the most vulnerable industry and largest target for cybercriminals, healthcare is facing an increasing wave of cyberattacks. When a hospital's systems are held hostage by ransomware, it’s not just data at risk — it’s the care of patients who depend on life-saving treatments. Imagine an attack that forces emergency care to halt, surgeries
GitLab has released patches to address a critical flaw impacting Community Edition (CE) and Enterprise Edition (EE) that could result in an authentication bypass

The US Cybersecurity and Infrastructure Security Agency is trying to eradicate cross-site scripting vulnerabilities
Broadcom on Tuesday released updates to address a critical security flaw impacting VMware vCenter Server that could pave the way for remote code execution
Our research reveals two significant vulnerabilities in Microsoft Azure Private 5G Core (AP5GC). The first vulnerability (CVE-2024-20685) allows a crafted signaling message to crash the control plane, leading to potential service outages. The second (ZDI-CAN-23960) disconnects and replaces attached base stations, disrupting network operations. While these issues are implementation-specific, their exploitation is made possible by a systemic weakness: the lack of mandatory authentication procedures between base stations and packet-cores.
The latest Secure by Design alert from CISA outlines recommended actions security teams should implement to reduce the prevalence of cross-site scripting vulnerabilities in software.
Bug reports made in China Broadcom has emitted a pair of patches for vulnerabilities in VMware vCenter Server that a miscreant with network access to the software could exploit to completely commandeer a system. This also affects Cloud Foundation.…
Broadcom has fixed a critical VMware vCenter Server vulnerability that attackers can exploit to gain remote code execution on unpatched servers via a network packet. [...]
CISA and the FBI urged tech companies to review their software and eliminate cross-site scripting (XSS) vulnerabilities before shipping. [...]
Roughly nine percent of tested firmware images use non-production cryptographic keys that are publicly known or leaked in data breaches, leaving many Secure Boot devices vulnerable to UEFI bootkit malware attacks. [...]
