CVE-2025-12388
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 B Carousel Block – Responsive Image and Content Carousel plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 1.1.5. This is due to the plugin not validating user-supplied URLs before passing them to the wp_remote_request() function. This makes it possible for authenticated attackers, with subscriber-level access and above, 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 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 · moderate confidenceThe B Carousel Block WordPress plugin fails to validate user-supplied URLs before passing them to wp_remote_request(), enabling authenticated attackers with subscriber-level access or higher to induce the server into making arbitrary HTTP requests to internal or external destinations.

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.
-
Verify B Carousel Block plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'B Carousel Block' in the list. Note whether it is active or inactive.Affected if The plugin is installed and active.
-
Determine installed plugin versionClick on the plugin name in the Plugins list to view details, or check the plugin files in wp-content/plugins/ for a version definition. Compare this version to the known affected version range.Affected if The installed version falls within the vulnerable version range.
-
Identify usage of the carousel blockCheck pages/posts for the B Carousel Block in the WordPress block editor, or query the wp_posts table for post_content containing 'b-carousel-block' or similar block identifiers.Affected if The block is present in published content and accepts URL input.
-
Inspect plugin source for vulnerable function callExamine the main plugin PHP file(s) for usage of wp_remote_request() without prior URL validation (such as wp_http_validate_url or similar sanitization functions).Affected if The code passes user input directly to wp_remote_request without validation.
-
Review server access logs for suspicious requestsSearch web server logs (Apache/Nginx error and access logs) for requests to internal IP addresses (127.0.0.1, 10.x.x.x, 192.168.x.x) or unusual external domains that correlate with potential exploitation of this endpoint.Affected if Logs show outbound requests from the web server to unexpected internal or external destinations initiated by lower-privileged users.
You are affected if the B Carousel Block plugin is installed, active, runs a vulnerable version without URL validation, and an authenticated user with subscriber-level access can submit URLs through the block.

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 dataUpdate to the latest version of the plugin to obtain the patched code with proper URL validation; alternatively, remove or disable the plugin until a fix is available.
