Hackers exploiting Acrobat Reader zero-day flaw since December
Attackers have been exploiting a zero-day vulnerability in Adobe Reader using maliciously crafted PDF documents since at least December. The attacks have been discovered by security researcher Haifei Li (the founder of the sandbox-based exploit-detection platform EXPMON), who warned on Tuesday that the attackers are using what he described as a “highly sophisticated, fingerprinting-style PDF exploit” to […]
13-year-old bug in ActiveMQ lets hackers remotely execute commands
Security researchers discovered a remote code execution (RCE) vulnerability in Apache ActiveMQ Classic that has gone undetected for 13 years and could be exploited to execute arbitrary commands. The flaw was uncovered using the Claude AI assistant, which identified an exploit path by analyzing how independently developed components interact. Tracked as CVE-2026-34197, the security issue received […]
Max severity Flowise RCE vulnerability now exploited in attacks
Hackers are exploiting a maximum-severity vulnerability, tracked as CVE-2025-59528, in the open-source platform Flowise for building custom LLM apps and agentic systems to execute arbitrary code. The flaw allows injecting JavaScript code without any security checks and was publicly disclosed last September, with the warning that successful exploitation leads to command execution and file system […]
Hackers exploit React2Shell in automated credential theft campaign
Hackers are running a large-scale campaign to steal credentials in an automated way after exploiting React2Shell (CVE-2025-55182) in vulnerable Next.js apps. At least 766 hosts across various cloud providers and geographies have been compromised to collect database and AWS credentials, SSH private keys, API keys, cloud tokens, and environment secrets. The operation uses a framework named NEXUS Listener and […]
Over 14,000 F5 BIG-IP APM instances still exposed to RCE attacks
Internet threat-monitoring non-profit Shadowserver has found over 14,000 BIG-IP APM instances exposed online amid ongoing attacks exploiting a critical-severity remote code execution (RCE) vulnerability. BIG-IP APM (short for Access Policy Manager) is F5’s centralized access management proxy solution designed to help admins secure access to their organizations’ networks, cloud, applications, and application programming interfaces (APIs). […]
New Progress ShareFile flaws can be chained in pre-auth RCE attacks
Two vulnerabilities in Progress ShareFile, an enterprise-grade secure file transfer solution, can be chained to enable unauthenticated file exfiltration from affected environments. Progress ShareFile is a document sharing and collaboration product typically used by large and mid-sized companies. Such solutions are an attractive target for ransomware actors, as previously seen in Clop data-theft attacks exploiting bugs in Accellion […]
GIGABYTE Control Center vulnerable to arbitrary file write flaw
The GIGABYTE Control Center is vulnerable to an arbitrary file-write flaw that could allow a remote, unauthenticated attacker to access files on vulnerable hosts. The hardware maker says that successful exploitation could potentially lead to code execution on the underlying system, privilege escalation, and a denial-of-service condition. The GIGABYTE Control Center (GCC), which comes pre-installed […]
Claude AI finds Vim, Emacs RCE bugs that trigger on file open
Vulnerabilities in the Vim and GNU Emacs text editors, discovered using simple prompts with the Claude assistant, allow remote code execution simply by opening a file. The assistant also created multiple versions of proof-of-concept (PoC) exploits, refined them, and provided suggestions to address the security issues. Vim and GNU Emacs are programmable text editors primarily […]
Hackers exploiting critical F5 BIG-IP flaw in attacks, patch now
Cybersecurity firm F5 Networks has reclassified a BIG-IP APM denial-of-service (DoS) vulnerability as a critical-severity remote code execution (RCE) flaw, warning that attackers are exploiting it to deploy webshells on unpatched devices. BIG-IP APM (short for Access Policy Manager) is a centralized access management proxy solution that enables admins to secure and manage user access […]
Critical Fortinet Forticlient EMS flaw now exploited in attacks
Attackers are now actively exploiting a critical vulnerability in Fortinet’s FortiClient EMS platform, according to threat intelligence company Defused. Tracked as CVE-2026-21643, this SQL injection vulnerability allows unauthenticated threat actors to execute arbitrary code or commands on unpatched systems through low-complexity attacks targeting the FortiClientEMS GUI (web interface) via maliciously crafted HTTP requests. “Fortinet Forticlient EMS […]
