What are common security mistakes in Bubble apps?
Get instant answers about your app's security.
Short Answer
The mistakes we see repeatedly in Bubble apps: missing privacy rules; public api workflows; plugin security risks. Each one is a specific failure mode of Bubble's workflow — not generic programming mistakes.
Detailed Answer
The mistakes we actually see in Bubble apps
These aren't hypothetical — they're what vas finds when it scans a Bubble app for the first time. Listed in order of how often they appear:
1. Missing Privacy Rules
*Why it happens:* Data types without privacy rules expose all data to all users. *What it's cost teams:* Security researchers regularly find Bubble apps with fully exposed databases.
*Fix:* Configure privacy rules for EVERY data type in Data → Privacy.
2. Public API Workflows
*Why it happens:* API workflows are public by default—anyone can call them.
*Fix:* Check 'This workflow requires authentication' on all API workflows.
3. Plugin Security Risks
*Why it happens:* Third-party plugins have access to your data with varying security.
*Fix:* Audit plugins. Remove unused ones. Only use trusted developers.
4. Visible Database Structure
*Why it happens:* Network requests reveal database schema to inspecting users.
*Fix:* Assume structure is known. Rely on privacy rules for security.
5. Client-Side Logic Visibility
*Why it happens:* Workflow logic partially visible in browser developer tools.
*Fix:* Move sensitive operations to backend workflows.
Why these specifically show up in Bubble (and not as much elsewhere)
Bubble's workflow optimizes for speed — idea to deployed app in minutes. The mistakes above aren't character flaws, they're the predictable output of a speed-optimized workflow that doesn't enforce security gates. "Missing Privacy Rules" is high-likelihood in Bubble specifically because nothing in Bubble's UI flows blocks it. The fix is treating security gates as non-negotiable, not as "I'll get to it later."

Expert Perspectives
“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
“It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.”

How common are these mistakes in Bubble apps — is this overstated?
Understated, if anything. The majority of Bubble apps scanned for the first time have at least one of the high-likelihood mistakes above. "Missing Privacy Rules" in particular is the default state of a new Bubble app before any security work. Our sample skews toward apps whose owners care enough to scan — the base rate for never-scanned Bubble apps is higher.
What are the actual consequences when these mistakes ship to production?
The consequence ladder: (a) data exposure — emails, passwords, PII, payment info readable by anyone; (b) account takeover — if auth is weak, legitimate accounts get hijacked; (c) third-party abuse — an exposed OpenAI or Stripe key gets drained of quota or money; (d) regulatory — GDPR/CCPA notification requirements trigger at ~first exposure; (e) reputational — "Bubble app data breach" is a headline that doesn't age well. Each consequence compounds the next.
How do I avoid these mistakes when building with Bubble?
Three non-negotiable habits: (1) Configure database access controls at table/collection creation — before writing any feature code. (2) Treat any paste-a-key-into-code as a bug from the first keystroke, not "I'll move it to env vars later." (3) Run a vas scan before every production deploy — five minutes of scanning prevents hours-to-weeks of breach response. Specifically: Configure privacy rules for EVERY data type in Data → Privacy..
