Background for this topic.
A flaw is a defect in software, hardware, system design, or configuration that causes unintended behavior. In security reporting, the term usually means a weakness that could violate confidentiality, integrity, or availability when reached through a particular interface, input, privilege, or operating condition. Not every flaw is exploitable, and exploitability depends on factors such as exposure, authentication requirements, affected versions, and available mitigations.
Flaws matter because they can create attack paths in applications, operating systems, devices, APIs, or administrative settings. Security teams assess their severity and exposure, prioritize remediation, apply patches or configuration changes, and use isolation or access controls when immediate fixes are unavailable. Code review, testing, vulnerability scanning, and monitoring can reveal flaws across the development and operational lifecycle. Reports should distinguish a confirmed vulnerability from a theoretical defect and provide enough technical detail to support validation without unnecessarily enabling exploitation.
The U.S. Cybersecurity & Infrastructure Security Agency (CISA) warns that a Craft CMS remote code execution flaw is being exploited in attacks. [...]
Cisco has confirmed that a Chinese threat actor known as Salt Typhoon gained access by likely abusing a known security flaw tracked as CVE-2018-0171, and by obtaining legitimate victim login credentials as part of a targeted campaign aimed at major U.S. telecommunications companies
A high-severity security flaw impacting the Craft content management system (CMS) has been added by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation
PoC exploit code shows why this is a patch priority Security engineers have released a proof-of-concept exploit for four critical Ivanti Endpoint Manager bugs, giving those who haven't already installed patches released in January extra incentive to revisit their to-do lists.…
Don't think this is SaaS and you can relax: Redmond wants a few of you to check your websites Microsoft has fixed a security flaw in its Power Pages website-building SaaS, after criminals got there first – and urged users to check their sites for signs of exploitation.…
Also: Lee Enterprises Recovering From Ransomware Attack, an Ivanti POCThis week, a FBI warning on Ghost ransomware, Lee Enterprises confirmed its ransomware attack, a proof-of-concept for Ivanti EPM flaws and a cybersecurity flaw in a Xerox machine. Also, a Chinese cyberespionage hacker apparently moonlighted as a ransomware attacker and NioCorp hit by a cyber heist.
Bugs fixed, updating to the latest version is advisable Security sleuths found two critical vulnerabilities in a third-party library that MongoDB relies on, which means bad guys can potentially steal data and run code.…
Palo Alto Networks has observed exploit attempts chaining three vulnerabilities in its PAN-OS firewall appliances
A previously unknown threat activity cluster targeted European organizations, particularly those in the healthcare sector, to deploy PlugX and its successor, ShadowPad, with the intrusions ultimately leading to deployment of a ransomware called NailaoLocker in some cases
Citrix has released security updates for a high-severity security flaw impacting NetScaler Console (formerly NetScaler ADM) and NetScaler Agent that could lead to privilege escalation under certain conditions
Microsoft has released security updates to address two Critical-rated flaws impacting Bing and Power Pages, including one that has come under active exploitation in the wild
A flaw in the Jupiter X Core plugin has been identified, allowing upload of malicious SVG files and remote code execution on vulnerable servers
The authentication bypass vulnerability in the OS for the company's firewall devices is under increasing attack and being chained with other bugs, making it imperative for organizations to mitigate the issue ASAP.
Palo Alto Networks warns that hackers are actively exploiting a critical authentication bypass flaw (CVE-2025-0108) in PAN-OS firewalls, chaining it with two other vulnerabilities to breach devices in active attacks. [...]

If you want to avoid urgent patches, stop exposing management consoles to the public internet A flaw patched last week by Palo Alto Networks is now under active attack and, when chained with two older vulnerabilities, allows attackers to gain root access to affected systems.…
Rapid Patching Urged: Flaws Pose Man-in-the-Middle Attack, Denial of Service RisksMillions of servers are at risk from vulnerabilities in OpenSSH, a widely used, open source remote server management and file transfer tool. The flaws pose man-in-the-middle attack and denial of service exploit risks, and have been patched in the latest version of OpenSSH.
OpenSSH has released security updates addressing two vulnerabilities, a machine-in-the-middle (MitM) and a denial of service flaw, with one of the flaws introduced over a decade ago. [...]
Significant OpenSSH flaws are exposing systems to man-in-the-middle and denial-of service attacks
Two security vulnerabilities have been discovered in the OpenSSH secure networking utility suite that, if successfully exploited, could result in an active machine-in-the-middle (MitM) and a denial-of-service (DoS) attack, respectively, under certain conditions
