Impact

Operator session tokens are stored in plaintext in the operator sessions table (the token column is the PRIMARY KEY). The session token is a 32-byte random hex value sent directly in a cookie and valid for 24 hours.
  • internal/models/operator.go:61 — OperatorSession.Token holds the plaintext token.
  • internal/store/sqlite operators.go:590 — CreateOperatorSession inserts sess.Token verbatim.
  • internal/store/sqlite operators.go:603,642,681,698 — lookups/updates/deletes use WHERE token = ? against the plaintext value.
Anyone who can read the database (backup, snapshot, file copy, or SQL-level disclosure) obtains every active session token and can hijack operator sessions directly, with no further authentication.
This is functionally identical to the plaintext enrollment-token issue fixed in GHSA-ghmh-jhmj-wcmf. API keys (OperatorAPIKey.KeyHash) and enrollment tokens (EnrollmentToken.TokenHash) already store only a SHA256 hash; session tokens were missed.

Patches

Store only a SHA256 hash of the session token, mirroring API keys and enrollment tokens:
  1. Add a HashSessionToken helper (alongside the existing token-hash helpers).
  2. Migration to add a token hash column.
  3. Update CreateOperatorSession, PromoteOperatorSession, and GetOperatorBySession to write/look up by hash.
  4. Drop the plaintext token column in a follow-up migration.
Sessions are ephemeral (24h TTL), so all active sessions can be invalidated on deployment — no backward compatibility needed.

Workarounds

Restrict and encrypt database backups; rotate the operator database. These mitigate exposure but do not fix the underlying storage of plaintext tokens.
