CVE-2025-13903: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ctietze PullQuote
The PullQuote plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'pullquote' shortcode in all versions up to, and including, 1.0 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-2025-13903 is a stored cross-site scripting vulnerability in the PullQuote WordPress plugin (versions up to 1.0). It arises from improper neutralization of input in the 'pullquote' shortcode, allowing authenticated contributors or higher to inject arbitrary web scripts. The vulnerability results from inadequate sanitization and escaping of user-supplied attributes, enabling script execution in the context of any user viewing the injected page. The CVSS 3.1 base score is 6.4 (medium severity), with network attack vector, low attack complexity, requiring privileges of a contributor or higher, no user interaction, and impacts confidentiality and integrity with no availability impact.
Potential Impact
An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the 'pullquote' shortcode. These scripts execute in the browsers of users who view the compromised pages, potentially leading to unauthorized actions or data disclosure within the context of the affected site. The impact affects confidentiality and integrity but does not affect availability. There are no known exploits in the wild currently.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should restrict contributor-level access to trusted individuals and consider disabling or removing the PullQuote plugin until a vendor-provided update or patch is released. Monitor the vendor's advisory channels for updates regarding remediation.
