CVE-2025-58978 Overview
CVE-2025-58978 is a missing authorization vulnerability affecting the WP Swings PDF Generator for WordPress plugin (pdf-generator-for-wp). The flaw stems from incorrectly configured access control security levels, allowing unauthenticated attackers to reach plugin functionality that should be restricted. The issue affects all versions of PDF Generator for WordPress up to and including 1.5.4. The vulnerability is categorized under [CWE-862] Missing Authorization and is exploitable over the network without user interaction or privileges.
Critical Impact
Unauthenticated attackers can access protected plugin functionality, resulting in limited disclosure of information from affected WordPress sites.
Affected Products
- WP Swings PDF Generator for WordPress plugin
- All versions from n/a through 1.5.4
- WordPress sites with pdf-generator-for-wp installed and active

Technical Details for CVE-2025-58978
Vulnerability Analysis
The vulnerability originates in the WP Swings PDF Generator for WordPress plugin, which fails to enforce proper authorization checks on one or more of its exposed actions or endpoints. According to the Patchstack Vulnerability Report, the plugin exposes functionality without validating whether the requesting user holds the required capability or role. This condition permits attackers with no authenticated session to interact with functionality intended for privileged users. The impact is limited to confidentiality, with no direct impact to integrity or availability of the WordPress installation.
Root Cause
The root cause is a missing authorization check [CWE-862] in the plugin's request handling logic. The plugin does not consistently apply WordPress capability checks such as current_user_can() or nonce validation via check_ajax_referer() before executing sensitive actions. As a result, access decisions rely on assumptions about the caller rather than explicit verification against the WordPress permission model.
Attack Vector
Exploitation requires only network access to the target WordPress site. An attacker sends crafted HTTP requests directly to the vulnerable plugin endpoint, bypassing the intended access boundary. No credentials, user interaction, or elevated privileges are needed. Successful exploitation may allow the attacker to trigger plugin functionality or read information that should be restricted to authorized roles.
No public proof-of-concept exploit code has been published for this vulnerability. Refer to the Patchstack advisory for additional technical context.
Detection Methods for CVE-2025-58978
Indicators of Compromise
- Unauthenticated HTTP requests to pdf-generator-for-wp endpoints, including admin-ajax.php calls invoking plugin-specific actions.
- Unexpected PDF generation activity or file downloads originating from unauthenticated sessions in web server access logs.
- Repeated probing of plugin paths under /wp-content/plugins/pdf-generator-for-wp/ from a single source address.
Detection Strategies
- Inspect WordPress access logs for requests to plugin AJAX actions lacking a valid authentication cookie or referer.
- Compare installed plugin versions against 1.5.4 and flag any host running the vulnerable release.
- Deploy WAF rules that require authenticated sessions for sensitive pdf-generator-for-wp action parameters.
Monitoring Recommendations
- Alert on spikes in requests to /wp-admin/admin-ajax.php containing PDF Generator action names from unauthenticated clients.
- Track outbound traffic and file operations initiated by the PHP worker processes associated with WordPress.
- Correlate plugin enumeration attempts with subsequent access to plugin-controlled endpoints across the estate.
How to Mitigate CVE-2025-58978
Immediate Actions Required
- Identify all WordPress installations with the pdf-generator-for-wp plugin installed and determine the installed version.
- Update PDF Generator for WordPress to a version later than 1.5.4 once a fixed release is available from WP Swings.
- If a patched version is not yet available, deactivate and remove the plugin until a fix is published.
Patch Information
At the time of publication, the vulnerability affects PDF Generator for WordPress versions through 1.5.4. Administrators should consult the Patchstack Vulnerability Report and the WP Swings vendor page for the current fixed version, then apply the update through the WordPress plugin manager or WP-CLI.
Workarounds
- Restrict access to /wp-admin/admin-ajax.php calls targeting PDF Generator actions using web server or WAF rules.
- Enforce IP allowlisting on WordPress administrative endpoints where operationally feasible.
- Apply virtual patching through a managed WordPress security service until the plugin is updated.
