What is CVE-2026-108522?

A vulnerability has been identified in Studio-Saelix Sencho versions up to 0.94.1, specifically affecting the Login Endpoint at /api/auth/login. The flaw allows a remote attacker to manipulate the X-Forwarded-For header, leading to improper authentication. This was due to the login limiter's reliance on client-supplied data without an explicit trusted-proxy boundary, enabling the attacker to spoof the originating client address. The recommended solution involves applying a patch that disregards forwarding headers by default, permitting them only from pre-configured proxy CIDRs, and implementing a distinct limit on failed login attempts based on normalized account identities.

Affected Version(s)

Sencho 0.94.0

Sencho 0.94.1

Exploit Proof of Concept (PoC)
