What vulnerabilities are found in Bubble apps?
Get instant answers about your app's security.
Short Answer
Scans of Bubble apps surface a recurring set of findings: missing privacy rules, public api workflows, and plugin security risks. 1 of these have documented real-world exploitation.
Detailed Answer
The vulnerabilities actually found in Bubble apps
Not theoretical OWASP categories — specifically what appears when VAS, security researchers, and bug bounty hunters look at live Bubble deployments:
- **[CRITICAL]** **Missing Privacy Rules** *(high likelihood)*
Data types without privacy rules expose all data to all users.
*Observed:* Security researchers regularly find Bubble apps with fully exposed databases.
*Fix:* Configure privacy rules for EVERY data type in Data → Privacy.
2. **[CRITICAL]** **Public API Workflows** *(high likelihood)*
API workflows are public by default—anyone can call them.
*Fix:* Check 'This workflow requires authentication' on all API workflows.
3. **[HIGH]** **Plugin Security Risks** *(medium likelihood)*
Third-party plugins have access to your data with varying security.
*Fix:* Audit plugins. Remove unused ones. Only use trusted developers.
4. **[MEDIUM]** **Visible Database Structure** *(medium likelihood)*
Network requests reveal database schema to inspecting users.
*Fix:* Assume structure is known. Rely on privacy rules for security.
5. **[MEDIUM]** **Client-Side Logic Visibility** *(low likelihood)*
Workflow logic partially visible in browser developer tools.
*Fix:* Move sensitive operations to backend workflows.
Distribution by severity
Of the findings above, 2 sit at critical impact (full data exposure), 1 at high (significant data or account compromise), and the rest are medium-or-lower (attack surface expansion). A first-scan Bubble app typically has 2–4 findings from this list live at any moment.
How to know which ones are in your app
Run a VAS scan. Each finding above is tested directly — we query your database to verify access controls are active, scan bundles for key patterns, probe auth endpoints for rate limiting, and check security headers in live responses. Output is a per-finding report with evidence and fix.

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 severe are the vulnerabilities typically found in Bubble apps?
Bubble apps lean critical: Missing Privacy Rules alone can expose the full user dataset in one query. That's a critical-impact finding with high likelihood — it is, in practice, the default state of an unscanned Bubble app. Compare to e.g. missing security headers (medium) which require additional exploitation. Triage accordingly: critical findings are measured in minutes-to-breach, mediums in weeks.
How do I fix vulnerabilities once they're found in my Bubble app?
Each finding comes with a specific fix. Example: for "Missing Privacy Rules" → Configure privacy rules for EVERY data type in Data → Privacy. VAS exports these as markdown you can feed directly into Bubble's AI (or any other AI assistant) to apply the fix in-place. Re-scan afterward to confirm.
Can vulnerabilities in Bubble apps be exploited by a non-expert attacker?
Most can. Extracting an exposed API key is a single "view source" operation. Querying a table without RLS is a `curl` command. Exploiting missing rate limiting requires scripting skills equivalent to "follow a tutorial." Only a handful of the findings above (e.g., chained auth bypass) require specialist knowledge — the rest are routinely exploited by automated scanners with zero human involvement.
