grafana: Grafana: Denial of Service via excessive memory allocation from large API request payloads

A flaw in Grafana's API endpoints allows remote attackers to send excessively large request bodies without authentication. This exhausts server memory, resulting in a complete denial of service DoS...

A SoK for SoCs: Reading the TI Leaves on AI for Cyber Threat Intelligence Generation and Sharing

Cyber Threat Intelligence CTI is essential for defending mission-critical infrastructure, yet the process of transforming raw attack evidence into shareable CTI remains fragmented and understudied. We conduct a literature survey of academic papers, organizing the CTI lifecycle into three stages:...

Using LLMs to Elicit Security Requirements for Service-Oriented Cyber Ranges

Cyber ranges are complex environments comprising many interacting components and stakeholders with different security concerns. The Service-Oriented Cyber Range SOR is no exception, particularly when it comes to training scenarios targeting critical infrastructure. Security concerns are translate...

CVE-2026-76763

SmallRye GraphQL contains a flaw in its number scalar coercion for BigInteger , which fails to properly validate the magnitude of float or string inputs. An unauthenticated remote attacker can send a GraphQL query containing a large exponent float literal, triggering the allocation of extremely l...

CVE-2026-77831 Algorithmic-complexity denial of service in AshPaperTrail full-diff list tracking

Inefficient Algorithmic Complexity vulnerability in ash-project ashpapertrail allows a user who can submit a large array attribute to a paper-trailed create or update action to cause a denial of service through excessive CPU and memory use. With full-diff change tracking,...

CVE-2026-42391

An unauthenticated attacker can send an IMAP ID command with a very large number of parameters before logging in, which causes memory and CPU usage to grow disproportionately. The login process can be terminated by the out-of-memory handling, which also terminates all other connections handled by...

CVE-2026-63384

A flaw was found in Libevent. An incorrect integer conversion in the evtagunmarshalheader function allows a remote attacker to provide a specially crafted payload length. This can lead to a wrapped large allocation request, resulting in a denial of service DoS for the affected system. Mitigation...
