Simply Schedule Appointments: Sensitive information exposure

The Simply Schedule Appointments plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.6.12.32 via the 'recursive' parameter. This makes it possible for unauthenticated attackers to extract customer PII — including names, email addresses, phone numbers, and custom form field data — stored in appointment records, as well as per-appointment public_token values. The leaked per-appointment public_token values also enable unauthenticated attackers to delete arbitrary appointments via the DELETE /wp-json/ssa/v1/appointments/{id} endpoint, which accepts the token as sole authorization.

CWE-862 — Missing Authorization

This CVE was published Oct 01, 2026 and is one of 43 known issues for this plugin.

What to do

Update, patch or deactivate.

No confirmed fixed release is identified. Disable the affected feature or deactivate the component until an upstream fix is confirmed. Upstream 1.6.12.33 is available and may resolve this issue, but its changelog does not clearly establish a matching fix; it is not marked safe here. Apply appointment-level authorization during recursive expansion and never return another customer's public_token. Rotate exposed tokens and review appointment deletions.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
