CVE-2026-14244 in Slider Plugin
Summary
by MITRE • 07/08/2026
The Jssor Slider by jssor.com plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 3.1.24 via the 'url' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.

The jssor slider plugin for wordpress represents a widely used content management tool that enables website administrators to create dynamic image sliders and carousels. This particular vulnerability affects versions up to and including 3.1.24, creating a significant security risk for wordpress installations that utilize this plugin. The directory traversal flaw manifests through improper input validation within the 'url' parameter handling mechanism, allowing attackers to manipulate file paths and gain unauthorized access to server resources.
The technical implementation of this vulnerability stems from inadequate sanitization of user-supplied input in the plugin's file handling routines. When the 'url' parameter is processed without proper validation or encoding checks, it becomes possible for malicious actors to inject '../' sequences that traverse directory structures. This weakness directly maps to common software security flaws classified under CWE-22, which specifically addresses improper limitation of a pathname to a restricted directory. Attackers can exploit this vulnerability by crafting malicious URLs that target system files such as configuration files, database credentials, or other sensitive information stored on the web server.
The operational impact of this vulnerability extends beyond simple information disclosure, creating potential pathways for more sophisticated attacks within compromised wordpress environments. Unauthenticated attackers can systematically explore the server filesystem, potentially discovering administrative credentials, database connection strings, or other configuration data that could facilitate further exploitation. This vulnerability represents a critical risk for wordpress installations where the jssor plugin is deployed, as it allows arbitrary file reading without requiring any authentication credentials or privileged access. The implications are particularly severe given that many wordpress sites store sensitive data in easily accessible locations within their file systems.
Mitigation strategies for this directory traversal vulnerability should focus on immediate plugin updates to versions that have addressed the input validation flaws. System administrators must ensure that all wordpress installations utilizing jssor slider are updated to the latest available version that contains proper parameter sanitization measures. Additionally, implementing web application firewalls with rules specifically designed to detect and block directory traversal attempts can provide an additional layer of protection. Security monitoring should include regular scanning for vulnerable plugin versions within wordpress installations, while network segmentation and access control measures can limit potential damage from successful exploitation attempts. Organizations should also consider implementing the principle of least privilege for web server file permissions to minimize information disclosure even if traversal attacks are successful. This vulnerability demonstrates the critical importance of maintaining up-to-date third-party components in web applications and highlights how seemingly minor input validation issues can create significant security risks that align with attack patterns documented in the mitre att&ck framework under technique t1213 for data from information repositories.
