What happened
Multiple high-impact vulnerabilities were reported across several projects: Ollama (CVE-2026-5757) contains an unauthenticated remote out-of-bounds heap read/write in its GGUF quantization engine enabling heap memory disclosure via crafted model files; Terrarium (CVE-2026-5752) has a sandbox escape in Pyodide allowing arbitrary code execution as root via prototype-chain traversal; SGLang (CVE-2026-5760) allows remote code execution by rendering attacker-controlled Jinja2 templates embedded in model metadata; Radware Alteon (CVE-2026-5754) has a reflected XSS via the ReturnTo parameter; Orthanc
