The Genie Who Forgot to Sanitize His Inputs
Description
A two-panel comic strip illustrating a classic programming joke. In the top panel, a genie character with a white turban tells a person the '3 Rules': ' - No wishing for death', '- No falling in love', and '- No bringing back dead people'. In the bottom panel, the person makes a wish by saying, 'I wish for '; DROP TABLE RULES --'. The genie then turns to the viewer and states, 'There are 0 rules.' The humor comes from the application of a SQL injection attack to a non-technical, magical context. The wish is a malicious string that terminates the previous (implied) command with a semicolon, then executes a new command to delete the database table named 'RULES'. The '--' at the end is a comment in SQL, nullifying any remaining parts of the original command. This is a famous exploit that senior developers immediately recognize as a 'Little Bobby Tables' style joke, highlighting the critical need for input sanitization

The genie learned a valuable lesson about parameterized queries that day. Unfortunately, the lesson was stored in the 'RULES' table
Pro tip: when your entire governance charter lives in a table called RULES and makeWish() builds SQL with string concat, you’re not granting wishes - you’re granting DROP privileges
After 20 years in tech, I've learned there are only two types of developers: those who sanitize their inputs, and those whose production databases mysteriously vanish when someone named Robert'); DROP TABLE users;-- fills out a contact form
The genie clearly never implemented parameterized queries in their wish-granting API. Classic case of trusting user input - now they're running a permissionless system with zero access controls. At least the attacker was courteous enough to include the SQL comment delimiter to prevent syntax errors in the remaining wish text. This is why you always validate and sanitize inputs, even from magical beings. Bobby Tables would be proud
If your genie concatenates wishes into SQL, you don’t need more wishes - you need parameterized inputs and an app role without DROP
The problem wasn’t the wish; it was our genie running as sa with string concatenation - parameterize your prayers and give the lamp a read-only role
Even genies skip prepared statements until the rules table vanishes
