Clawdrain: Exploiting Tool-Calling Chains for Stealthy Token Exhaustion in OpenClaw Agents

Modern generative agents such as OpenClaw - an open-source, self-hosted personal assistant with a community skill ecosystem, are gaining attention and are used pervasively. However, the openness and rapid growth of these ecosystems often outpace systematic security evaluation. In this paper, we...

Security Bulletin: IBM Watson Speech Services Cartridge is vulnerable to a Data Amplification in urllib3 [ CVE-2026-21441]

Summary IBM Watson Speech Services Cartridge is vulnerable to a Data Amplification in urllib3, due to a flaw that library reads the entire response body to drain the connection and decompress the content unnecessarily, rather than decompressing only the necessary bytes as expected CVE-2026-21441...

firefox: thunderbird: expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing

A memory amplification vulnerability in libexpat allows attackers to trigger excessive dynamic memory allocations by submitting specially crafted XML input. A small input 250 KiB can cause the parser to allocate hundreds of megabytes, leading to denial-of-service DoS through memory exhaustion...
