CRITICAL CVE-2026-66446 Deferred

If-So permits Subscriber-level SQL injection

If-So through 1.10 allows a Subscriber to supply data that reaches an unsafe database query, enabling SQL injection. Version 1.10.0.1 is fixed. Its prose explicitly requires a Subscriber even though the published CVSS vector encodes no privileges required; this archive retains the stated role and leaves the vector inconsistency unresolved.

Weakness
CWE-89 — Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

This CVE was published Aug 13, 2026 and is one of 10 known issues for this plugin.

Update, patch or deactivate.

Update to 1.10.0.1 or later. Audit Subscriber accounts and database or access logs, and rotate secrets if database information may have been exposed.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

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.
