CVE-2026-1542
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Super Stage WP WordPress plugin through 1.0.1 unserializes user input via REQUEST, which could allow unauthenticated users to perform PHP Object Injection when a suitable gadget is present on the blog.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Super Stage WP WordPress plugin through version 1.0.1 contains a PHP Object Injection vulnerability where user-supplied data from the REQUEST superglobal is passed to PHP's unsafe unserialize() function. Unauthenticated attackers can exploit this to inject arbitrary PHP objects when a suitable gadget chain exists elsewhere on the WordPress installation, potentially leading to remote code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Super Stage WP plugin is installedNavigate to WordPress admin dashboard under Plugins > Installed Plugins, or inspect the wp-content/plugins/ directory for a folder named 'super-stage-wp' or similarAffected if The plugin appears in the installed plugins list or filesystem
-
Identify the installed plugin versionOpen the main plugin PHP file (usually super-stage-wp.php or similar in the plugin folder) and look for the plugin header comment containing 'Version:' or a $version variable definitionAffected if The version is 1.0.1 or lower (any version through 1.0.1 is affected)
-
Locate the vulnerable unserialize callSearch the plugin source code files for the pattern 'unserialize($_REQUEST' or 'unserialize( $_REQUEST' to locate the unsafe deserialization entry pointAffected if Code containing 'unserialize($_REQUEST' is found in the plugin files
-
Verify REQUEST parameter handling is reachable without authenticationExamine the function or method containing the unserialize call to determine if it is hooked to an action accessible to unauthenticated users (such as init, wp_ajax_nopriv_*, or admin_init without capability checks)Affected if The vulnerable function is hooked to a public or auth-optional WordPress action without access controls
You are affected if the Super Stage WP plugin is installed with version 1.0.1 or lower and contains the unsafe unserialize($_REQUEST) call in code reachable by unauthenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched version of the Super Stage WP plugin that replaces unsafe unserialize() with secure deserialization (e.g., JSON). If no patch exists, consider removing the plugin until a fix is available.
