Analysis Overview

Atomic Edge analysis of CVE-2026-27416: The PDF Poster plugin for WordPress (version ≤ 2.4.1) contains a missing authorization vulnerability in the REST API endpoint used to retrieve post metadata. This allows unauthenticated attackers to access metadata of published posts (including sensitive configuration fields) through a specific API route. The CVSS score of 5.3 indicates moderate severity with a network-based attack vector and no authentication required.

The root cause lies in the file `/pdf-poster/inc/Rest/getMeta.php`. The vulnerable code at line 42 performed an insufficient check: `if ($post_type !== ‘pdfposter’)`. While it verified the post type, it did not verify that the post was published. The function returned an empty response only for non-`pdfposter` types, but allowed access to any `pdfposter` post regardless of its status. The `WP_REST_Request` class instance allowed an attacker to supply a post ID, and the subsequent code (not shown in the diff but implied) would retrieve metadata via `get_post_meta` for the given ID without checking the current user’s permissions.

The exploitation method is simple: an unauthenticated attacker sends a GET request to the WordPress REST API endpoint `wp-json/pdfp/v1/get-meta?id=N`, where N is the numeric ID of a published post of the `pdfposter` post type. Alternatively, the attacker could target posts with different statuses, but the patch specifically blocks non-published posts. The attacker does not need a nonce or any special privileges. The response will include all metadata fields stored under the `_fpdf` meta key, including file paths, button configurations, popup settings, social share settings, and PDF display options. This reveals internal plugin configuration and potentially the paths to uploaded PDF files.

The patch adds an additional condition to the existing check in `getMeta.php` at line 42. The new code reads: `if ($post_type !== ‘pdfposter’ || $post->post_status !== ‘publish’)`. This changes the logic to reject requests where the post is not published. Previously, the condition only checked the post type; now it also verifies that the post’s status equals `’publish’`. The patch forces the REST endpoint to return an empty `WP_REST_Response` array for any post that is not both a ‘pdfposter’ and in the ‘publish’ status. This effectively prevents unauthenticated attackers from retrieving metadata of unpublished, draft, or otherwise non-public posts.

If exploited, an unauthenticated attacker can retrieve metadata from published `pdfposter` posts. The metadata (`_fpdf`) contains configuration settings including the source URL/path to the PDF file, display options (height, width), button configurations (background color, text), popup trigger settings, social share settings (Facebook, Twitter, LinkedIn, etc.), and other plugin-specific options. This information leakage may expose the location of PDF files that were intended to be embedded on specific pages but could now be downloaded directly. In the context of Privacy Mode protection (if enabled), the attacker learns the PDF source URL which could circumvent intended access controls. The vulnerability does not allow direct remote code execution or database manipulation, but the information disclosure could aid further targeted attacks.
