CVE-2025-11827: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in oboxgroup Oboxmedia Ads
The Oboxmedia Ads plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'before_widget' and 'after_widget' parameters of the oboxads-ad-widget shortcode in all versions up to, and including, 1.9.8. This is due to insufficient input sanitization and output escaping. 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-2025-11827 is a stored cross-site scripting vulnerability in the Oboxmedia Ads WordPress plugin (versions up to 1.9.8). The issue is due to improper neutralization of input in the 'before_widget' and 'after_widget' parameters of the oboxads-ad-widget shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users viewing the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and requiring privileges but no user interaction.
Potential Impact
An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via vulnerable shortcode parameters. These scripts execute in the browsers of users who visit the affected pages, potentially compromising user sessions or performing unauthorized actions within the context of the victim's browser. The vulnerability does not impact availability and requires authenticated access, limiting its scope to users with some level of site access.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory channels for updates. Until a fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Oboxmedia Ads plugin if possible to mitigate risk.
