CVE-2026-1899: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in itpathsolutions Any Post Slider
The Any Post Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's aps_slider shortcode in all versions up to, and including, 1.0.4 due to insufficient input sanitization and output escaping on the 'post_type' attribute. 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-2026-1899 is a stored cross-site scripting vulnerability in the Any Post Slider WordPress plugin (versions up to 1.0.4). The issue stems from improper neutralization of input in the 'post_type' attribute of the aps_slider shortcode, enabling authenticated users with Contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users who visit the injected pages, potentially leading to session hijacking or other script-based attacks. 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).
Potential Impact
An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode attribute. When other users access these pages, the scripts execute in their browsers, potentially leading to information disclosure and integrity impacts such as session hijacking or unauthorized actions. Availability is not affected. No known exploits are currently reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit Contributor-level access to trusted users only and consider disabling or removing the Any Post Slider plugin if possible to prevent exploitation.
