2DescriptionCVE.org
The Tiled Gallery Carousel Without JetPack plugin for WordPress is vulnerable to stored cross-site scripting via the 'data-image-title' parameter in all versions up to, and including, 3.1 due to insufficient input sanitization and output escaping. 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.
AnalysisAI
Stored cross-site scripting in the Tiled Gallery Carousel Without JetPack WordPress plugin (versions up to and including 3.1) allows authenticated attackers with contributor-level access to inject persistent malicious JavaScript via the 'data-image-title' parameter. The injected script executes in victims' browsers each time an affected gallery page is visited, enabling session theft, credential harvesting, or malicious redirects against site visitors and administrators. No public exploit or CISA KEV listing has been identified at time of analysis, though the low privilege barrier (contributor access) broadens the potential attacker pool on sites with open registration.
Technical ContextAI
The vulnerability exists in the jetpack-carousel.js script (see plugins.trac.wordpress.org reference, line 1057), where image title data supplied by contributors is rendered into page output without adequate sanitization or output encoding. CWE-79 (Improper Neutralization of Input During Web Page Generation) identifies the root cause as failure to escape user-controlled data before HTML/JS context insertion. The CPE string cpe:2.3:a:raja3c:tiled_gallery_carousel_without_jetpack:*:*:*:*:*:*:*:* confirms the affected vendor is raja3c and the wildcard version range covers all releases through 3.1. Because the XSS is stored (persisted in the database) rather than reflected, a single injection affects every subsequent page load - amplifying impact relative to reflected variants. The CVSS S:C (Changed Scope) attribute confirms the script can reach resources outside the vulnerable component, consistent with cross-browser cookie and DOM access.
RemediationAI
No specific patched version number is confirmed in the available reference data; the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/2e2ab3b3-0d24-4b3d-8668-cc2bcf08d12f should be consulted for the latest patch status and any released fix version. As an immediate compensating control, administrators should restrict the contributor role on affected WordPress installations - specifically, prevent untrusted or externally registered users from holding contributor-level access or higher until a patch is applied. If the Tiled Gallery Carousel Without JetPack plugin is not actively required, deactivating and removing it eliminates the attack surface entirely with no functional side effects beyond losing the gallery carousel feature. WordPress site owners using Wordfence Premium may have access to a firewall rule blocking exploitation of this parameter. Auditing existing gallery content for unexpected script tags in image title fields is advisable to detect any prior injection.
