Sensitive Data Exposure (CWE-312): Cleartext Storage of Sensitive Information

Reachability: Internal · Exploitability: Difficult

Do not persist OAuth tokens in plaintext.

The OAuth repository writes access and refresh tokens directly to oauth_tokens. Encrypt both values before persistence, and keep the encryption key outside the database.

Encode the Basic credentials before this request.

After variable substitution, the header sends the raw client_id:client_secret pair. HTTP Basic authentication requires Base64 encoding of that pair, or the token exchange can fail authentication.

Remove consumed OAuth parameters from the fallback query string.

When the callback uses window.location.search, Line 34 rebuilds the URL with the original search string. The oauth and reason parameters therefore remain after replaceState. A refresh can replay the toast. Remove the consumed parameters from both the hash and search sources before rebuilding the URL.
