Security Alert Summary
The Otter Blocks WordPress plugin (versions before 3.2.8) incorrectly determines whether a post is publicly readable before returning its data via a REST API endpoint. As a result, unauthenticated users may be able to read manual excerpts of password-protected posts, view content and titles of non-public post types, and, on WooCommerce sites, see coupon codes and their descriptions.

Technical Details
The plugin fails to correctly determine whether a post is publicly readable before returning its data through a REST API endpoint. Specifically, the code treats any post with the published status as public and does not apply the expected visibility checks for non-public content.
Because the visibility check is insufficient, unauthenticated requests to the affected REST API endpoint can receive manual excerpts of password-protected posts, the content and titles of non-public post types, and — on sites using WooCommerce — coupon codes and their descriptions. The description identifies the problem as an information exposure via the REST API behavior rather than an authentication bypass requiring credentials.
How This Could Impact Your Website
Consider a small team managing a WordPress site where the site owner configures private posts for internal processes, an editor stores draft content, and an external contractor publishes promotional coupons via WooCommerce. Because the plugin can return excerpts and titles for non-public items to unauthenticated requests, an attacker could gather details about unpublished content, coupon values, or promotional codes without logging in.
Practical consequences include exposure of non-public content that could inform targeted phishing or social engineering, and disclosure of coupon codes that undermine marketing campaigns or revenue controls. If your site stores internal notes or draft titles that reveal business plans, those details could be viewed without authorization.
If youre unsure whether your site is affected or how to assess your current user roles and plugins, it may be worth having a professional review.
Recommended Actions
- Update the affected plugin as soon as a patched version is available.
- Review and reduce unnecessary user roles, especially contributor-level accounts and other low-privilege roles that can create content visible via REST responses.
- Enforce strong passwords and enable two-factor authentication for editors and administrators.
- Remove unused or unmaintained plugins to reduce attack surface.
- Monitor site activity and REST API logs for unusual or unexpected read requests to post endpoints.
