Organizations are urged to review their security measures and apply necessary updates to safeguard against these evolving threats.

Fortinet has issued a warning about ongoing attacks that exploit an old vulnerability in its FortiOS software, identified as CVE-2020-12812. This flaw allows attackers to bypass two-factor authentication, which can significantly compromise the security of affected systems. Organizations using FortiOS should be particularly vigilant, as this vulnerability has resurfaced in active attacks. The potential for unauthorized access puts sensitive data at risk, making it critical for users to address this issue promptly. Cybersecurity teams are urged to review their systems and implement necessary updates to safeguard against these threats.

Fortinet has issued a warning about a vulnerability in FortiOS that has been around for five years but is still being exploited by attackers. This flaw allows unauthorized users to bypass two-factor authentication (2FA) on FortiGate firewalls, which are widely used by organizations to secure their networks. The continued exploitation of this vulnerability poses a significant risk to companies relying on these firewalls, as it can lead to unauthorized access and potential data breaches. Users of FortiGate firewalls are urged to take immediate action to protect their systems by applying available security updates. This situation serves as a reminder of the importance of keeping software up to date and addressing known vulnerabilities promptly.

A newly discovered vulnerability in MongoDB, referred to as MongoBleed, poses a significant risk by allowing remote attackers to extract sensitive information from affected servers without authentication. This flaw has been exploited in real-world attacks, raising alarms among organizations that utilize MongoDB for their data management. The vulnerability's ability to leak data could expose sensitive customer information, business secrets, and other critical data. Companies using MongoDB should prioritize patching their servers to mitigate potential breaches. It's crucial for users to remain vigilant and ensure their systems are secure against this emerging threat.

A serious vulnerability in MongoDB, designated as CVE-2025-14847 and known as MongoBleed, is currently being exploited globally. This flaw, which has a CVSS score of 8.7, allows attackers to access sensitive data stored in the server's memory without needing authentication. Researchers have identified over 87,000 instances of MongoDB that could be affected by this issue. The potential for data leakage poses a significant risk to organizations using this database technology, making it critical for them to address the vulnerability promptly. Companies should assess their systems and implement necessary security measures to safeguard against this ongoing threat.

A serious vulnerability known as MongoBleed (CVE-2025-14847) is currently being exploited, exposing over 80,000 MongoDB servers on the public internet. This flaw affects multiple versions of MongoDB, allowing attackers to potentially access sensitive information stored on these servers. The scale of the exposure raises significant security concerns, as many organizations may not be aware that their databases are at risk. Companies using affected MongoDB versions should take immediate action to secure their data and prevent unauthorized access. Failure to address this vulnerability could lead to severe data breaches and loss of sensitive information.

The 2022 LastPass breach continues to pose risks, as attackers are still able to crack encrypted vault backups using weak master passwords. This vulnerability allows for potential cryptocurrency theft, with experts from TRM Labs warning that such thefts could occur as late as 2025. Users who stored sensitive information in LastPass and have not changed their passwords are particularly at risk. This incident emphasizes the importance of using strong, unique passwords and regularly updating them, especially after a security breach. As the situation evolves, individuals and businesses using LastPass should remain vigilant and consider additional security measures.

Fortinet has alerted users about the active exploitation of a five-year-old vulnerability in its FortiOS SSL VPN, identified as CVE-2020-12812. This flaw, which has a CVSS score of 5.2, involves improper authentication and is particularly dangerous under specific configurations. Researchers have recently observed this vulnerability being abused in real-world attacks, which means organizations using affected versions of FortiOS SSL VPN should take immediate action to secure their systems. The ongoing exploitation of such an outdated vulnerability underscores the need for companies to regularly update their security measures and ensure proper configuration to protect against potential attacks.

Fortinet has reported that a five-year-old vulnerability in its FortiOS SSL VPN is being actively exploited. This flaw, identified as CVE-2020-12812, allows attackers to bypass two-factor authentication under specific configurations, enabling unauthorized access to systems. Organizations using affected versions of FortiOS SSL VPN should be particularly vigilant, as this vulnerability could lead to significant security breaches. The issue emphasizes the need for users to ensure their VPN configurations are secure and up-to-date. Fortinet's warning serves as a critical reminder of the importance of addressing known vulnerabilities, even those that have been around for several years.

On Monday, the French national postal service, La Poste, experienced a significant disruption due to a Distributed Denial of Service (DDoS) attack. The attack caused central computer systems to go offline, impacting operations across the postal service. Pro-Russian hacker groups have claimed responsibility for the incident, raising concerns about the motivations behind such attacks amid ongoing geopolitical tensions. This incident not only disrupts postal services but also highlights the vulnerability of critical infrastructure to cyber threats. As La Poste works to restore services, this event serves as a reminder of the increasing frequency and severity of cyberattacks targeting essential services.
