CVE-2025-26958
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 · uneditedMissing Authorization vulnerability in Crocoblock JetBlog jet-blog allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects JetBlog: from n/a through <= 2.4.3.
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 confidenceMissing Authorization (Broken Access Control) vulnerability in Crocoblock JetBlog plugin allows unauthenticated users to access functionality that should be restricted by Access Control Lists (ACLs). This enables attackers to bypass proper authorization checks and interact with privileged functions within the jet-blog component.

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 JetBlog plugin installationIn WordPress admin, go to Plugins > Installed Plugins and confirm the 'JetBlog' plugin by Crocoblock is active. Alternatively, check the /wp-content/plugins/jet-blog/ directory exists.Affected if JetBlog plugin is installed and active
-
Identify installed JetBlog versionCheck the plugin header in /wp-content/plugins/jet-blog/jet-blog.php for the 'Version' field, or look in WordPress admin under Plugins > JetBlog.Affected if Unable to determine version or version is unknown/outdated
-
Test for unauthenticated endpoint accessSend a request to common JetBlog AJAX endpoints (such as /wp-admin/admin-ajax.php?action=jet_blog_*) without providing authentication cookies or nonces. Use a tool like curl or Burp Suite to observe responses.Affected if Requests to jet_blog AJAX actions return successful responses without requiring login or valid nonce tokens
-
Check REST API exposureQuery /wp-json/jet-blog/v1/* endpoints without authentication headers. Examine if sensitive endpoints return data or perform actions that should require elevated privileges.Affected if REST API endpoints under jet-blog namespace respond to unauthenticated requests with privileged data or functionality
-
Verify authorization capability checksReview JetBlog PHP source code for the presence of current_user_can(), check_admin_referer(), or nonce verification before executing privileged functions in jet-blog.php and related files.Affected if No capability checks (current_user_can) or nonce validation found before sensitive operations in the jet-blog component
If JetBlog is installed and its AJAX/REST endpoints are accessible without authentication or proper capability verification, the environment is affected by this broken access control vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 dataImplement proper authorization checks (capability verification, nonce validation, and role-based access control) on all sensitive functions and endpoints within the JetBlog plugin. Ensure all functionality that requires ACL constraints properly validates user permissions before execution.
