CVE-2025-11857: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in mxp XX2WP Integration Tools
The XX2WP Integration Tools plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mxp_fb2wp_display_embed' shortcode in all versions up to, and including, 1.9.9. This is due to the plugin not properly sanitizing user input and output of the 'post_id' parameter. 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-2025-11857 is a stored cross-site scripting vulnerability in the XX2WP Integration Tools WordPress plugin, affecting all versions up to 1.9.9. The issue arises from improper neutralization of input in the 'post_id' parameter used by the 'mxp_fb2wp_display_embed' shortcode. Authenticated attackers with contributor or higher privileges can inject arbitrary web scripts that execute in the context of users visiting the compromised pages. The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). No official patch or fix is currently documented.
Potential Impact
Successful exploitation allows an authenticated contributor-level or higher user to inject persistent malicious scripts into pages, which execute in the browsers of users who visit those pages. This can lead to limited confidentiality and integrity impacts, such as theft of session tokens or modification of page content. There is no direct impact on availability. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the XX2WP Integration Tools plugin if it is not essential. Monitor for updates from the vendor regarding patches or official fixes.
