8.1 HIGH

Network, unauthenticated, no interaction, but gated on a non-default APP_ENV!=production condition outside attacker control (AC:H); RCE via module installer yields full C/I/A impact.

DescriptionCVE.org

Lara Dashboard before 1.3.0 contains an authentication bypass vulnerability in the screenshot-login route that allows unauthenticated attackers to authenticate as any user by email when APP_ENV is not production. Attackers can request the GET /screenshot-login/{email} endpoint with a registered email address to receive a fully authenticated session, enabling access to user administration, settings, database contents, and arbitrary code execution through the module installer.

AnalysisAI

Authentication bypass in Lara Dashboard before 1.3.0 lets unauthenticated attackers log in as any registered user by requesting GET /screenshot-login/{email}, provided the deployment runs with APP_ENV set to anything other than production. The route was a demo-screenshot helper (used by an internal Browsershot command with superadmin@example.com) that was reachable in non-production environments, granting a fully authenticated session that reaches user administration, settings, database contents, and arbitrary code execution via the module installer. …
