Security readout for executives and security teams
Plain-English summary
CVE-2025-31094 is a stored cross-site scripting issue in the WordPress WP Posts Carousel plugin through version 1.3.8. A logged-in attacker may be able to store malicious script that runs when another user views affected content. Business risk is moderate because compromise depends on privileges and user interaction, but successful abuse can affect site integrity and user trust.
Executive priority
Handle in the normal vulnerability queue with priority for externally facing WordPress sites and sites with many content contributors. Escalate if the plugin is broadly deployed or untrusted users have publishing access.
Technical view
The vulnerability is CWE-79 stored XSS in teastudio.pl WP Posts Carousel, package wp-posts-carousel, affecting versions up to 1.3.8. CVSS 3.1 is 6.5 with network attack vector, low complexity, low privileges required, user interaction required, and changed scope. The source bundle does not identify a patched version or detailed vulnerable parameter.
Likely exposure
Exposure is limited to WordPress sites with WP Posts Carousel installed at version 1.3.8 or earlier. Sites allowing multiple authors, editors, or lower-trust authenticated users are more exposed than tightly administered sites.
Exploitation context
The source bundle does not show active exploitation, and CISA KEV status is false. The CVSS vector indicates an authenticated attacker and victim interaction are required. No exploit details are provided here.
Researcher notes
Evidence is limited to CVE metadata and the Patchstack VDB entry. Do not assume a specific vulnerable field, exploit availability, or patched version from the provided bundle. Validation should focus on asset inventory, version confirmation, role exposure, and vendor advisory follow-up.
Mitigation direction
- Inventory WordPress sites for WP Posts Carousel and record installed versions.
- Prioritize any installation running version 1.3.8 or earlier.
- Check Patchstack and vendor guidance for a fixed release or workaround.
- Limit plugin/content editing rights to trusted users while remediation is pending.
- Consider temporary disablement where the plugin is unnecessary or risk is unacceptable.
Validation and detection
- Confirm whether wp-posts-carousel is installed on each WordPress site.
- Verify plugin version and flag any instance at 1.3.8 or earlier.
- Review users with author, editor, administrator, or plugin-management privileges.
- Inspect recent carousel-related content changes for unexpected script-like markup.
- After remediation, retest affected pages for stored script execution symptoms.
