WooCommerce is testing a new extension Settings UI while preserving legacy settings behavior. Password and API secret fields need special tests because a masked placeholder or blank value can overwrite a valid stored credential.
Use this for payment, shipping, tax, CRM, and fulfillment extensions that store secrets through WooCommerce settings.
Quick answer
WooCommerce Settings UI Secret Field Masking Audit should be handled with a narrow evidence-first workflow: map secret behavior, test untouched save, test clear and replace, then verify the result before making broader changes.
What to check first
- Map the secret field, option key, masking pattern, validation callback, and runtime consumer.
- Load and save the screen without touching the field, then compare the stored value hash.
- Test blank input, masked placeholder, valid replacement, invalid replacement, and cancel behavior.
- Run one sandbox request to prove the extension uses the intended credential after each safe case.
- Switch between legacy and new settings screens and confirm the same option remains intact.
Diagnostic table
Use this table to keep the work practical. It connects the symptom to evidence and a verification step.
| Action | Evidence to collect | How to verify |
| Map secret behavior | Map the secret field, option key, masking pattern, validation callback, and runtime consumer. | An untouched save preserves the credential. |
| Test untouched save | Load and save the screen without touching the field, then compare the stored value hash. | Clear and replacement behavior match the field documentation. |
| Test clear and replace | Test blank input, masked placeholder, valid replacement, invalid replacement, and cancel behavior. | Invalid input cannot corrupt the prior valid secret. |
| Prove runtime use | Run one sandbox request to prove the extension uses the intended credential after each safe case. | The extension completes a sandbox request with the intended credential. |
Why this usually happens
- The browser may submit a mask that the server mistakes for a new secret.
- Blank fields can mean preserve or clear depending on the extension.
- Client-side validation may not match the legacy PHP sanitizer.
- A success notice does not prove the runtime client loaded the expected value.
Useful command or data shape
Adapt paths, IDs, and privacy handling to the site before running commands or storing data on production.
wp option get woocommerce_example_settings --format=json | jq 'del(.api_secret)'
# Compare a one-way hash or secret version before and after save.
# Run a sandbox API request without printing authorization headers.
Safe fix order
Do the work in a sequence that makes each result easy to prove. Stop if a step produces new evidence that changes the incident scope.
- Map secret behavior
- Test untouched save
- Test clear and replace
- Prove runtime use
- Test legacy rollback
What to tell the client or owner
Report only secret version or hash evidence, save case, option owner, runtime result, and rollback path.
Production verification checklist
- An untouched save preserves the credential.
- Clear and replacement behavior match the field documentation.
- Invalid input cannot corrupt the prior valid secret.
- The extension completes a sandbox request with the intended credential.
Mistakes to avoid
- Do not judge the fix by one browser or the homepage only.
- Do not delete evidence before recording usernames, file paths, timestamps, and response headers.
- Do not add a cache, security, or tracking plugin while the original problem is still unclear.
- Do not leave test users, temporary debug logs, or broad API keys active after verification.
When HandL WP should help
Bring in help when this affects leads, checkout, search visibility, malware risk, paid media reporting, or a client production site. HandL WP can trace the issue through WordPress, hosting, cache, tracking, and Search Console, then verify the workflow after the technical fix.
If this is active on a production site, test WooCommerce extension settings before production.
