Doc Text:
HostList.list() catches bare Exception and returns str(e) verbatim. Via host_filter, any authenticated user triggers Django FieldError (leaking complete Host model relation graph including internal reverse accessors) or PostgreSQL DataError (leaking raw database error strings). Two primitives: credential__search=x dumps ORM schema, name__regex=[bad reflects PostgreSQL errors.

Description OSIDB Bzimport 2026-08-06 23:11:30 UTC
A flaw was found in automation-controller. The HostList view catches bare Exception in its list() method and returns str(e) verbatim to the caller. An attacker can trigger Django FieldError exceptions via crafted host_filter parameters to leak the complete Host model relation graph including internal reverse accessors, or trigger PostgreSQL DataError exceptions to leak raw database error strings.
