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.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a high-severity flaw impacting Sierra Wireless AirLink ALEOS routers to its Known Exploited Vulnerabilities (KEV) catalog, following reports of active exploitation in the wild
Apple on Friday released security updates for iOS, iPadOS, macOS, tvOS, watchOS, visionOS, and its Safari web browser to address two security flaws that it said have been exploited in the wild, one of which is the same flaw that was patched by Google in Chrome earlier this week
Apple has released emergency updates to patch two zero-day vulnerabilities that were exploited in an "extremely sophisticated attack" targeting specific individuals. [...]
Exploit hasn't been picked up by any malware detection engines, CEO tells The Reg A Microsoft zero-day vulnerability that allows an unprivileged user to crash the Windows Remote Access Connection Manager (RasMan) service now has a free, unofficial patch - with no word as to when Redmond plans to release an official one - along with a working exploit circulating online.…
And the earlier React2Shell patch is vulnerable If you're running React Server Components, you just can't catch a break. In addition to already-reported flaws, newly discovered bugs allow attackers to hang vulnerable servers and potentially leak Server Function source code, so anyone using RSC or frameworks that support it should patch quickly.…
Critical vulnerabilities found in third-party applications eligible for award under 'in scope by default' move Microsoft is overhauling its bug bounty program to reward exploit hunters for finding vulnerabilities across all its products and services, even those without established bounty schemes.…
Wiz says React2Shell attacks accelerating, ranging from cryptominers to state-linked crews Half of the internet-facing systems vulnerable to a fast-moving React remote code execution flaw remain unpatched, even as exploitation has exploded into more than a dozen active attack clusters ranging from bargain-basement cryptominers to state-linked intrusion tooling.…
Free unofficial patches are available for a new Windows zero-day vulnerability that allows attackers to crash the Remote Access Connection Manager (RasMan) service. [...]
CISA has ordered U.S. federal agencies to patch a critical GeoServer vulnerability now actively exploited in XML External Entity (XXE) injection attacks. [...]
The React team has released fixes for two new types of flaws in React Server Components (RSC) that, if successfully exploited, could result in denial-of-service (DoS) or source code exposure
MITRE has shared this year's top 25 list of the most dangerous software weaknesses behind over 39,000 security vulnerabilities disclosed between June 2024 and June 2025. [...]
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has urged federal agencies to patch the recent React2Shell vulnerability by December 12, 2025, amid reports of widespread exploitation
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a high-severity security flaw impacting OSGeo GeoServer to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation in the wild
Hackers are exploiting a new, undocumented vulnerability in the implementation of the cryptographic algorithm present in Gladinet's CentreStack and Triofox products for secure remote file access and sharing. [...]
Wiz disclosed a still-unpatched vulnerability in self-hosted Git service Gogs, which is a bypass for a previous RCE bug disclosed last year.
Unpatched Flaw in Open-Source Gogs Service Facilitates Remote Code ExecutionAn attacker has been exploiting a zero-day vulnerability in Gogs, an open-source and popular Git service that allows for self-hosting, warned researchers. At least 700 internet-exposed servers running Gogs shows signs of being infected with command-and-control malware; no patch is yet available.
No details, no CVE, update your browser now Google issued an emergency fix for a Chrome vulnerability already under exploitation, which marks the world's most popular browser's eighth zero-day bug of 2025.…
Microsoft now pays security researchers for finding critical vulnerabilities in any of its online services, regardless of whether the code was written by Microsoft or a third party. [...]
An unpatched zero-day vulnerability in Gogs, a popular self-hosted Git service, has enabled attackers to gain remote code execution on Internet-facing instances and compromise hundreds of servers. [...]
A high-severity unpatched security vulnerability in Gogs has come under active exploitation, with more than 700 compromised instances accessible over the internet, according to new findings from Wiz
