Strong Testimonials: Authenticated unsafe deserialization

Strong Testimonials is a WordPress plugin affected through 3.3.12. The CNA vector requires low-privileged authenticated access, but no exact WordPress role is disclosed. In this vulnerability, untrusted serialized input reaches object deserialization; the CNA rates confidentiality, integrity and availability impacts high, but the export does not establish a particular object chain or code-execution path. The export does not disclose a concrete endpoint, action, parameter, function, or full input-to-operation path beyond those facts. The completed CNA record identifies 3.3.13 as fixed.

CWE-502 — Deserialization of Untrusted Data

This CVE was published Oct 18, 2026 and is one of 21 known issues for this plugin.

Update, patch or deactivate.

Update Strong Testimonials to 3.3.13 or a later supported release. The completed CNA record identifies this fixed boundary. Do not deserialize attacker-controlled input into application objects; use a validated data-only format instead.

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.
