At a glance
CVE-2026-1294 is a high-severity Server-Side Request Forgery (SSRF) vulnerability in the All In One Image Viewer WordPress plugin, affecting versions <= 1.0.2. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.0.3; sites on affected versions should update now. Disclosed February 2026, reported by Athiwat Tiprasaharn (Jitlada).
Vulnerability Overview
The All In One Image Viewer Block plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.0.2 due to missing authorization and URL validation on the image-proxy REST API endpoint. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-918: Server-Side Request Forgery (SSRF)
Reaching this weakness in All In One Image Viewer <= 1.0.2 takes no account at all. Server-side request forgery means the application fetches a URL supplied by the caller, turning the server into a proxy for requests the attacker could not make directly.
The request originates from inside the hosting network, which is how these flaws reach cloud metadata endpoints, internal admin panels and services that trust local traffic. For All In One Image Viewer the fix is 1.0.3: builds <= 1.0.2 are affected, anything from 1.0.3 onward is not.
Remediation
Update to version 1.0.3, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All In One Image Viewer 1.0.3 closes this, and updating the plugin is the step that ends it.
