CVE-2026-6801: Context Blog WordPress Information Disclosure

CVE-2026-6801 Overview

CVE-2026-6801 is a sensitive information exposure vulnerability in the Context Blog theme for WordPress. The flaw affects all versions up to and including 1.3.5. The context_blog_modal_popup function fails to enforce access controls on password-protected post content. Unauthenticated attackers can retrieve the content of password-protected posts over the network without credentials or user interaction. The issue is categorized under [CWE-200] (Exposure of Sensitive Information to an Unauthorized Actor).

Critical Impact
Remote, unauthenticated attackers can extract the plaintext content of password-protected WordPress posts served by sites running the Context Blog theme.

Affected Products

Context Blog theme for WordPress, versions up to and including 1.3.5
WordPress sites using the context_blog_modal_popup feature
Any deployment relying on the Context Blog theme for password-protected post confidentiality

Technical Details for CVE-2026-6801

Vulnerability Analysis

The Context Blog theme exposes post content through the context_blog_modal_popup handler used to render post previews inside a modal on the front end. The handler returns post body content without validating whether the requesting user has supplied the correct password for posts protected by WordPress's built-in password protection feature.

WordPress normally gates password-protected posts behind the post_password_required() check. The Context Blog implementation bypasses this gate by loading raw post content directly for display in the modal preview. As a result, the response includes the same body text that would otherwise require the correct password to view.

The vulnerability has a network attack vector, requires no privileges, and needs no user interaction. Impact is limited to confidentiality; integrity and availability of the site are not affected.

Root Cause

The root cause is a missing authorization check in the context_blog_modal_popup endpoint. The theme's modal preview logic reads post content directly rather than deferring to WordPress's password enforcement helpers, effectively treating protected posts as public.

Attack Vector

An attacker sends an unauthenticated HTTP request to the WordPress site targeting the context_blog_modal_popup action for a known password-protected post ID. The response contains the protected post content in plaintext. Attackers can enumerate post IDs to harvest content at scale. See the Wordfence Vulnerability Report and the WordPress Theme Changeset for the underlying code path and fix.

No verified public exploit code is available for this vulnerability at the time of publication.

Detection Methods for CVE-2026-6801

Indicators of Compromise

Unauthenticated admin-ajax.php or REST requests referencing the context_blog_modal_popup action from external IP addresses
Sequential or scripted enumeration of post or p identifiers against the modal popup endpoint
Elevated response sizes from the modal popup endpoint returning full post bodies rather than teaser content
Web server access logs showing high-frequency GET or POST requests to Context Blog theme endpoints from a single client

Detection Strategies

Alert on unauthenticated requests to the context_blog_modal_popup handler that return HTTP 200 with non-trivial payload sizes
Baseline normal request rates to theme AJAX endpoints and flag deviations consistent with ID enumeration
Use a web application firewall rule to identify requests targeting the vulnerable action prior to patching

Monitoring Recommendations

Forward WordPress access logs and PHP error logs into a centralized analytics platform such as Singularity Data Lake for query-driven hunting across sites
Track the version string of the Context Blog theme across managed WordPress installations and flag any host still running 1.3.5 or earlier
Monitor outbound traffic from the web tier for signs of bulk content exfiltration following suspicious enumeration activity

How to Mitigate CVE-2026-6801

Immediate Actions Required

Update the Context Blog theme to a version later than 1.3.5 once the vendor publishes a fix, using the WordPress Theme Changeset as the reference commit
Audit all password-protected posts and rotate any secrets, links, or data that may have been exposed while the site ran an affected version
Restrict access to the modal popup endpoint at the web server or WAF layer until the theme is upgraded

Patch Information

The upstream fix is tracked in the WordPress themes repository under changeset 329636 for the Context Blog theme. Site administrators should apply the released update through the WordPress admin dashboard or via wp theme update context-blog using WP-CLI. Verify the installed version reports higher than 1.3.5 after the update.

Workarounds

Deactivate and remove the Context Blog theme until a patched version is installed, switching to a default WordPress theme temporarily
Add a WAF rule blocking unauthenticated requests that reference the context_blog_modal_popup action parameter
Move highly sensitive content out of password-protected posts and into an authenticated area gated by a membership or role-based plugin

bash

# Example WP-CLI update workflow once a patched version is available
wp theme status context-blog
wp theme update context-blog
wp theme get context-blog --field=version
