Vulnerability / Container Security
Cybersecurity researchers have discovered five vulnerabilities in Fluent Bit , an open-source and lightweight telemetry agent, that could be chained to compromise and take over cloud infrastructures. The security defects "allow attackers to bypass authentication, perform path traversal, achieve remote code execution, cause denial-of-service conditions, and manipulate tags," Oligo Security said in a report shared with The Hacker News. Successful exploitation of the flaws could enable attackers to disrupt cloud services, manipulate data, and burrow deeper into cloud and Kubernetes infrastructure. The list of identified vulnerabilities is as follows - CVE-2025-12972 - A path traversal vulnerability stemming from the use of unsanitized tag values to generate output filenames, making it possible to write or overwrite arbitrary files on disk, enabling log tampering and remote code execution. CVE-2025-12970 - A stack buffer overflow vulnerability in the Docker Metrics inp...
