Lifecycle Timeline
2DescriptionCVE.org
The Print, PDF, Email by PrintFriendly plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content_position_css' parameter in all versions up to, and including, 5.5.10 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AnalysisAI
Stored Cross-Site Scripting in the Print, PDF, Email by PrintFriendly WordPress plugin (versions through 5.5.10) allows authenticated administrators to inject persistent JavaScript via the 'content_position_css' parameter, which executes in the browsers of any user who visits an affected page. The scope change (S:C) in the CVSS vector confirms the injected script breaks out of the plugin's security context into victim browsers, enabling session hijacking, credential theft, or malicious redirects against site visitors. No public exploit code has been identified at time of analysis, and the vulnerability has not been added to the CISA KEV catalog.
Technical ContextAI
CWE-79 (Improper Neutralization of Input During Web Page Generation) is the root cause: the plugin stores user-supplied CSS positioning values from 'content_position_css' without adequate sanitization or output escaping, then renders those values directly into page HTML. Source code references in the WordPress plugin repository point to lines 367, 391, and 681 of pf.php in both the 5.5.8 and 5.5.10 tagged releases, indicating the vulnerable code is distributed across multiple render call sites - a pattern suggesting the fix required changes in several locations rather than a single sanitization point. The affected software is identified by CPE cpe:2.3:a:printfriendly:print,_pdf_&_email_by_printfriendly:*:*:*:*:*:*:*:* and operates as a WordPress plugin, meaning it inherits WordPress's user role model where 'administrator' is the minimum privilege level for exploiting this flaw.
RemediationAI
Update the Print, PDF, Email by PrintFriendly plugin to a version beyond 5.5.10. A code changeset is referenced at https://plugins.trac.wordpress.org/changeset?reponame=&old=3590593%40printfriendly&new=3590593%40printfriendly, indicating that upstream code changes have been committed; however, the exact released patched version number is not independently confirmed from the available data - verify the current version available from the WordPress plugin repository and confirm it exceeds 5.5.10 before deploying. As a compensating control where immediate update is not possible, restrict the WordPress administrator role to fully trusted personnel only and audit which users hold administrator-level access on affected sites. For WordPress multisite environments, review network-admin vs. site-admin privilege separation. The Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/43d54cb5-7813-4d30-a081-db84e0d29030 should be monitored for confirmed fixed version information.
