jinja2: Jinja sandbox breakout through attr filter selecting format method

A flaw was found in Jinja. In affected versions, an oversight in how the Jinja sandboxed environment interacts with the |attr filter allows an attacker who controls the content of a template to execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content o...

CVE-2026-44182 Jupyter Enterprise Gateway Has Kubernetes Manifest Injection via Jinja2 Template Rendering

PYSEC-2026-2518 Home Assistant Command-line Interface: Handling of user-supplied Jinja2 templates

Impact Up to 1.0.0 of home-assitant-cli or hass-cli for short an unrestricted environment was used to handle Jninja2 templates instead of a sandboxed one. The user-supplied input within Jinja2 templates was rendered locally with no restrictions. This gave users access to Python's internals and...

PYSEC-2026-2488 Giskard has Unsandboxed Jinja2 Template Rendering in ConformityCheck

Summary The ConformityCheck class in giskard-checks rendered the rule parameter through Jinja2's default Template constructor. Because the rule string is silently interpreted as a Jinja2 template, a developer may not realize that template expressions embedded in rule definitions are evaluated at...
