CVE-2025-8397: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in restpack Save as PDF Button
The Save as PDF Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's restpackpdfbutton shortcode in all versions up to, and including, 1.9.2 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-8397 is a stored cross-site scripting vulnerability in the Save as PDF Button WordPress plugin, affecting versions up to 1.9.2. The issue is due to improper neutralization of input during web page generation (CWE-79), specifically in the restpackpdfbutton shortcode. Authenticated attackers with contributor or higher privileges can inject malicious scripts via user-supplied shortcode attributes, which are not properly sanitized or escaped. These scripts execute in the context of users who view the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity.
Potential Impact
An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who view the affected pages, potentially compromising user sessions or data confidentiality and integrity. Availability is not impacted. The vulnerability affects the confidentiality and integrity of the WordPress site content and user data to a limited extent.
Mitigation Recommendations
No official patch or fix is currently documented for this vulnerability. Users should monitor the vendor's advisory channels for updates. Until a fix is available, restrict contributor-level access carefully and consider disabling or removing the Save as PDF Button plugin if possible to prevent exploitation.
