  • When ssl_verify_cert=True, ssl_verify_identity=True, an ssl.SSLContext is passed,
    or when any other SSL option is configured, the connection requires SSL and raises

v1.1.3

Compare Source

Release date: 2026-05-01

Security

• Fix Cursor.callproc() didn't escape procedure name. (#​1206)
  There was a possibility of SQL injection when calling a procedure with a string received from an untrusted source as the procedure name.

  NOTICE: This change may cause backward compatibility issues. If you specified a procedure name like "dbname.funcname", the previous version called CALL dbname.funcname, but from this version, it will call CALL `dbname.funcname` so you cannot specify procedure name with database name anymore.
