CVE-2025-2167: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in bastho Event post
The Event post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'events_list' shortcodes in all versions up to, and including, 5.9.9 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-2025-2167 is a stored cross-site scripting vulnerability in the bastho Event post WordPress plugin versions up to 5.9.9. The issue arises from improper neutralization of input during web page generation (CWE-79), specifically in the handling of the 'events_list' shortcode's user-supplied attributes. Authenticated attackers with contributor-level privileges or higher can inject arbitrary JavaScript code that executes in the context of users visiting the compromised pages. This vulnerability does not require user interaction beyond page access and has a CVSS 3.1 base score of 5.4, reflecting a network attack vector with low attack complexity and low privileges required.
Potential Impact
Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages generated by the plugin. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. There is no direct impact on availability. The vulnerability affects all users who view the injected pages, potentially exposing them to script-based attacks.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability as per the provided data. Users of the bastho Event post plugin should monitor the vendor's advisories for updates. Until a fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the plugin if possible to prevent exploitation. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
