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.
Security vulnerabilities discovered in Dormakaba's Saflok electronic RFID locks used in hotels could be weaponized by threat actors to forge keycards and stealthily slip into locked rooms
Network penetration testing plays a vital role in detecting vulnerabilities that can be exploited. The current method of performing pen testing is pricey, leading many companies to undertake it only when necessary, usually once a year for their compliance requirements. This manual approach often misses opportunities to find and fix security issues early on, leaving businesses vulnerable to
Details have emerged about a vulnerability impacting the "wall" command of the util-linux package that could be potentially exploited by a bad actor to leak a user's password or alter the clipboard on certain Linux distributions
Cybersecurity researchers from ETH Zurich have developed a new variant of the RowHammer DRAM (dynamic random-access memory) attack that, for the first time, successfully works against AMD Zen 2 and Zen 3 systems despite mitigations such as Target Row Refresh (TRR)
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a security flaw impacting the Microsoft Sharepoint Server to its Known Exploited Vulnerabilities (KEV) catalog based on evidence of active exploitation in the wild
Cybersecurity researchers are warning that threat actors are actively exploiting a "disputed" and unpatched vulnerability in an open-source artificial intelligence (AI) platform called Anyscale Ray to hijack computing power for illicit cryptocurrency mining
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday placed three security flaws to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation
In January 2024, Microsoft discovered they’d been the victim of a hack orchestrated by Russian-state hackers Midnight Blizzard (sometimes known as Nobelium). The concerning detail about this case is how easy it was to breach the software giant. It wasn’t a highly technical hack that exploited a zero-day vulnerability – the hackers used a simple password spray attack to take control of
A new security shortcoming discovered in Apple M-series chips could be exploited to extract secret keys used during cryptographic operations
