CVE-2025-62882 Overview
CVE-2025-62882 is a missing authorization vulnerability in the Seriously Simple Podcasting plugin for WordPress, developed by Craig Hewitt and maintained by Castos. The flaw stems from incorrectly configured access control checks that allow authenticated users with low privileges to perform actions reserved for higher-privileged roles. All versions of Seriously Simple Podcasting up to and including 3.13.0 are affected. The vulnerability is tracked under [CWE-862] (Missing Authorization) and carries a network attack vector with low complexity. Exploitation requires an authenticated account but no user interaction, and affects the integrity of plugin-managed data.
Critical Impact
Authenticated attackers with minimal privileges can perform unauthorized actions against podcast content and plugin functionality due to broken access control enforcement.
Affected Products
- Castos Seriously Simple Podcasting plugin for WordPress
- All versions from initial release through 3.13.0
- WordPress sites running the plugin with any authenticated user role enabled

Technical Details for CVE-2025-62882
Vulnerability Analysis
The Seriously Simple Podcasting plugin exposes functionality through WordPress action handlers and REST endpoints that fail to enforce proper capability checks. When a request reaches a protected function, the plugin verifies that a user is authenticated but does not validate whether the account holds the appropriate role or capability to perform the operation. This gap enables low-privileged users, such as subscribers, to invoke actions intended for editors or administrators. The impact is limited to integrity of plugin-controlled data, with no direct confidentiality or availability consequences reported in the advisory.
Root Cause
The root cause is a missing authorization check [CWE-862] in one or more request handlers within the plugin codebase. Developers relied on authentication as the sole gate, omitting current_user_can() capability validation or nonce-based intent checks before executing privileged operations. This pattern of broken access control is common in WordPress plugins that treat AJAX or REST endpoints as internal utilities.
Attack Vector
An attacker must first obtain a valid WordPress account on the target site. Once authenticated, the attacker sends crafted HTTP requests directly to the vulnerable plugin endpoints. Because the plugin skips role validation, the requests execute successfully and modify plugin state or podcast content. No social engineering or user interaction is required. Refer to the Patchstack Vulnerability Report for the specific endpoint details.
Detection Methods for CVE-2025-62882
Indicators of Compromise
- Unexpected modifications to podcast episodes, feeds, or plugin settings performed by non-administrator accounts
- HTTP POST requests to Seriously Simple Podcasting AJAX or REST endpoints originating from subscriber or contributor accounts
- WordPress audit log entries showing privileged plugin actions attributed to low-privileged users
Detection Strategies
- Review WordPress access logs for requests to plugin action handlers correlated with low-privileged user sessions
- Enable a security plugin that records capability checks and flags actions executed outside the expected role boundary
- Compare plugin content and configuration against known-good baselines to identify unauthorized changes
Monitoring Recommendations
- Alert on any write operation to podcast-related database tables initiated by accounts below the editor role
- Monitor for anomalous spikes in authenticated requests to /wp-admin/admin-ajax.php referencing Seriously Simple Podcasting actions
- Track new user registrations followed by requests to plugin endpoints within short time windows
How to Mitigate CVE-2025-62882
Immediate Actions Required
- Update the Seriously Simple Podcasting plugin to a version later than 3.13.0 as soon as the vendor publishes a patched release
- Audit existing WordPress user accounts and remove or downgrade any unnecessary low-privileged accounts
- Review recent podcast content and plugin configuration for unauthorized modifications
Patch Information
At the time of publication, the advisory identifies versions up to and including 3.13.0 as affected. Administrators should consult the Patchstack Vulnerability Report and the plugin repository for the fixed release. Apply updates through the WordPress plugin manager or via automated update policies once available.
Workarounds
- Restrict user registration to trusted individuals and disable open registration where feasible
- Deploy a web application firewall rule that blocks requests to Seriously Simple Podcasting endpoints from accounts below the editor role
- Temporarily deactivate the plugin if podcast functionality is not business-critical until a patched version is installed
