Summary
Gogs is an open source Git service that prior to version 0.14.3 accepted the authentication header without verifying that the request came from a trusted reverse proxy. This allowed attackers to impersonate users or trigger automatic account creation.
Risk Assessment
Attackers can exploit this vulnerability to bypass authentication mechanisms, posing a serious threat to the security of Gogs data and users.
Recommendation
It is recommended to update Gogs to version 0.14.3 or later to mitigate this vulnerability and implement additional security measures to verify the source of requests.
Original NVD description (English source)
Gogs is an open source self-hosted Git service. Prior to 0.14.3, when ENABLE_REVERSE_PROXY_AUTHENTICATION is enabled, Gogs accepts the configured authentication header (default: X-WEBAUTH-USER) directly from client requests without validating that the request originated from a trusted reverse proxy. Any remote attacker who can reach the Gogs service can forge this header to impersonate any user or trigger automatic account creation, completely bypassing authentication. This vulnerability is fixed in 0.14.3.
