CVE-2026-125112 djust: A template binding inherits a context safety grant it never earned (XSS)

2.3 lowEPSS 0.3%Fix available

Low (2.3) in djust-org djust. EPSS 0.3% estimated probability of exploitation activity in the next 30 days. Fixed in djust 1.0.10, 1.1.2.

On this page
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to versions 1.0.10 and 1.1.2, djust keys context output-safety grants by variable name and fails to revoke a grant when a template bind replaces the value associated with that name. A template using {% with %}, {% for %}, {% include ... with %}, tuple unpacking, or assign tags can therefore rebind a name that previously held mark_safe content and emit the new attacker-controlled value without escaping, including descendant lookups through the rebound name. This can cause stored or reflected cross-site scripting when a victim renders the affected template. This issue is fixed in versions 1.0.10 and 1.1.2.
