The Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent directive for U.S. federal agencies to patch a serious vulnerability found in GeoServer. This flaw is being exploited in XML External Entity (XXE) injection attacks, which can allow attackers to access sensitive data. The exploitation of this vulnerability poses a significant risk to the integrity and confidentiality of systems using GeoServer. Agencies are advised to take immediate action to defend against potential breaches and secure their data. Given that this vulnerability is actively being exploited, it is crucial for affected organizations to prioritize the necessary updates to protect their networks from compromise.

The React team has identified and patched two significant vulnerabilities in React Server Components (RSC) that could lead to denial-of-service (DoS) attacks and exposure of source code. These issues were uncovered by security researchers while they were probing the existing patches for a previously disclosed critical bug (CVE-2025-55182) that had a CVSS score of 10.0, indicating its severity. This situation is concerning as it affects developers using React for building applications, potentially putting sensitive code at risk. The React team emphasizes the importance of applying these patches promptly to maintain application security.

Hackers have taken advantage of a zero-day vulnerability in Gogs, a self-hosted Git service, leading to the compromise of approximately 700 servers that are accessible over the internet. This vulnerability allows attackers to execute code remotely, posing a significant risk to organizations and individuals using this platform to manage their Git repositories. Gogs, which is known for its lightweight and easy-to-deploy nature, is now under scrutiny as users scramble to secure their systems. The incident highlights the importance of promptly applying security updates and monitoring for unusual activity. Without swift action, affected servers could lead to data breaches or unauthorized access to sensitive information.

Researchers at Wiz have discovered a serious vulnerability in Gogs, a self-hosted Git service. This flaw allows attackers to bypass a previously reported remote code execution (RCE) vulnerability that was disclosed last year. Although the specifics of the exploitation have not been detailed, the revelation indicates that the vulnerability has been exploited for months without a patch available to fix it. This situation poses significant risks for organizations that rely on Gogs for their version control, as it could lead to unauthorized access and potentially severe security breaches. Users of Gogs need to stay vigilant and consider alternative security measures while waiting for a fix.

CyberVolk has reemerged with its new VolkLocker ransomware-as-a-service, which comes with some notable features but also a significant design flaw. Researchers have identified a major vulnerability that could allow security teams to mitigate attacks more effectively. This flaw raises concerns for businesses and organizations that could be targeted by this ransomware, as it may lead to increased incidents of data theft and disruption. Cyber defenders need to be vigilant and prepare for potential attacks stemming from this new variant. Understanding the weaknesses in VolkLocker could help in developing strategies to counteract its effects and protect sensitive information.

Hackers have taken advantage of a serious unpatched zero-day vulnerability in Gogs, a widely used self-hosted Git service, allowing them to execute remote code on exposed servers. This breach has impacted around 700 Internet-facing instances, putting sensitive data at risk and potentially leading to further attacks. The vulnerability is particularly concerning because it remains unpatched, leaving many servers vulnerable to exploitation. Users of Gogs should take immediate action to secure their systems, as the lack of a fix means attackers can easily compromise servers. This incident serves as a reminder for organizations to prioritize timely software updates and security measures to protect their infrastructure.

A recent phishing campaign has targeted around 6,000 companies, sending over 40,000 fraudulent emails that appeared to come from trusted services like SharePoint and DocuSign. These emails contained malicious links disguised by reputable redirect services, making it easier for scammers to trick recipients into clicking. The scale and speed of this attack raise concerns about the vulnerability of businesses to such tactics, which exploit the trust users place in well-known platforms. Companies need to be vigilant, as these phishing attempts can lead to data breaches or financial loss if employees fall for the scams. Ensuring proper training and awareness around phishing tactics is crucial for organizations to protect themselves.

Cybersecurity experts are reporting a surge in malware attacks exploiting a serious vulnerability in the React library, known as React2Shell. This vulnerability allows attackers to execute code remotely without authentication, putting many applications at risk. React is widely used for building user interfaces, meaning a broad range of developers and companies could be affected. The situation is concerning as it opens the door for various types of malware to be deployed against unsuspecting users. Companies using React should take immediate action to assess their systems and implement security measures to protect against these attacks.

A serious security vulnerability in Gogs, a self-hosted Git service, is currently being exploited, affecting over 700 instances worldwide. This flaw, identified as CVE-2025-8110, has a CVSS score of 8.7 and allows attackers to overwrite files via the file update API. The lack of a patch means that many users are at risk, and researchers from Wiz have highlighted the urgency of addressing this issue. Companies using Gogs should take immediate action to secure their installations and monitor for any signs of compromise. The situation underscores the need for timely updates and vigilance in managing self-hosted services.

Google has addressed a zero-day vulnerability in its Chrome browser that was actively exploited in the wild. This vulnerability, which does not have a CVE identifier, remains shrouded in mystery, as details about its origin and the specific components it affects are unclear. The lack of a CVE means users and security experts have limited information regarding the potential risks involved. However, the fact that it has been exploited means users should update their Chrome browsers promptly to safeguard against potential attacks. Keeping software up to date is crucial in mitigating risks associated with such vulnerabilities.

CVE-2025-55182 is currently being exploited by threat actors, raising concerns about the potential for increased attacks. This vulnerability affects a range of systems, and researchers have noted that their honeypots are already being targeted. In addition to the exploitation, specific malware has been identified as part of these attacks, which could compromise the integrity of affected systems. It’s crucial for organizations to understand the implications of this vulnerability and take proactive measures to protect their infrastructure. Knowing how to defend against this threat is vital as the situation evolves.

Researchers have identified a significant surge in attacks linked to a vulnerability in React2Shell, with more than 50 confirmed victims to date. This issue stems from a critical defect that has left many systems exposed, as reports indicate that about half of these vulnerable instances remain unpatched. The rapid exploitation of this flaw underscores the urgency for affected organizations to take immediate action to secure their systems. Companies using React2Shell need to prioritize updates and patch deployments to mitigate these risks. Failure to address this vulnerability could lead to more widespread damage and data breaches as attackers continue to exploit the flaw in the wild.
