2DescriptionCVE.org
The Smart Slider 3 plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.5.1.37 via the 'keyword' parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to extract titles and full content excerpts of private, draft, pending, trashed, and auto-draft posts authored by any user, including Administrators and Editors. The required nonce is emitted on /wp-admin/post-new.php, which is accessible to Contributor-level users via the edit_posts capability, meaning any Contributor can obtain the nonce needed to trigger the injection.
AnalysisAI
Sensitive information exposure in the Smart Slider 3 WordPress plugin (all versions up to and including 3.5.1.37) allows authenticated Contributor-level users to extract titles and full content excerpts of private, draft, pending, trashed, and auto-draft posts belonging to any user on the site - including Administrators and Editors - via the unsecured 'keyword' Ajax parameter. The attack barrier is further lowered because the required nonce is automatically emitted on /wp-admin/post-new.php, a page accessible to any Contributor by default through the edit_posts capability, making nonce acquisition trivial. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated WordPress account with at minimum Contributor-level privileges, specifically the edit_posts capability, which is assigned to the Contributor role by default in WordPress. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS 3.1 score of 4.3 Medium (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) accurately reflects a network-accessible, low-complexity attack with no user interaction, limited to confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A user registered as a Contributor on a target WordPress site logs in, navigates to /wp-admin/post-new.php, and extracts the nonce value embedded in the page source or JavaScript. The attacker then crafts an Ajax POST request to the Smart Slider 3 content endpoint with the 'keyword' parameter set to terms likely to match sensitive content - such as project names, client names, or embargo keywords - and receives back post titles and full excerpts for all matching private, draft, pending, and trashed posts belonging to Administrators and Editors. … |
| Remediation | A fix is available via WordPress plugin trac changeset 3599123 (https://plugins.trac.wordpress.org/changeset/3599123/smart-slider-3); administrators should update Smart Slider 3 to the version incorporating this changeset - the exact released patched version number is not independently confirmed from the provided data, so verify the current release version in the WordPress plugin directory or via the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/a782d975-74ce-4265-9312-435b3585a5c6 before acting. … Detailed patch versions, workarounds, and compensating controls in full report. |
