Vulnerability CVE-2026-121497 PLUGIN askany CRITICAL

Technical Summary

The AskAny WordPress plugin before 2.2.0 does not validate the extension or content of files attached to chat messages, trusting the browser-supplied file type instead, which allows unauthenticated users to upload PHP files and execute arbitrary code when visitor attachments are enabled.

Potential Impact

Severity is CRITICAL (CVSS 9.8). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as High based on low-bar exploit prerequisites.

Primary risk drivers: low-bar exploit prerequisites

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 96/100 (Critical, High) with priority P1 Immediate. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.

What to do about this

Patch immediately Serious, and reachable without meaningful privilege.

Fix it

Update AskAny to 2.2.0 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 AskAny, 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 AskAny. Versions below 2.2.0 are vulnerable; that release and later are not. No account is needed to exploit this, so a public site is reachable by anyone.

How do I fix it?

Update AskAny to version 2.2.0 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.

WordPress security that blocks attacks before they land.
