CVE-2026-19722

The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.133 does not validate the destination of files extracted from a backup package during restoration, allowing high privilege users such as administrators to write arbitrary files outside the intended restore directory, which can lead to code execution.

Technical Summary

The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.133 does not validate the destination of files extracted from a backup package during restoration, allowing high privilege users such as administrators to write arbitrary files outside the intended restore directory, which can lead to code execution.

Potential Impact

Severity is MEDIUM (CVSS 6.6). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as Medium based on severity and technical exposure profile.

Primary risk drivers: severity and technical exposure profile

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

AI risk score 57/100 (Elevated, Medium) with priority P3 Priority. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.

What to do about this

Low priority Contained impact, or it needs privileges an attacker would rarely already hold.

Fix it

Update WPvivid to 0.9.133 or later.

That is the complete fix. Everything below is what protects you in the meantime.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.

Not sure if you are affected?

Scan your site to see whether it runs WPvivid, and at which version.

Free, no installation, no account. It reads what your site already publishes, then tells you which plugins carry known vulnerabilities and what to do about each one.

Am I affected by this vulnerability?

You are affected if your site runs WPvivid. Versions below 0.9.133 are vulnerable; that release and later are not.

How do I fix it?

Update WPvivid to version 0.9.133 or later. That is the complete fix. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

What can an attacker actually do?

This is a Improper Input Validation flaw. An attacker who exploits it can submit values the application never expected, with effects that vary by feature.
