Official description
AstronRPA through 1.1.6 contains an authentication bypass vulnerability in the OpenResty gateway's auth_handler.lua that accepts any Bearer token without validation. Unauthenticated attackers can send arbitrary Bearer values to reach /api/resource/ and /api/rpa-ai-service/ routes and spoof X-User-Id or user_id headers to act as any user.

The underlying weakness: Improper Authentication
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
How developers prevent this class of flaw
- Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
