Security readout for executives and security teams
Plain-English summary
CVE-2026-31916 is a medium-severity broken access control issue in the WordPress Latest Post Shortcode plugin through version 14.2.1. An unauthenticated network attacker may access information they should not be authorized to view. The available sources do not state that integrity or availability are impacted.
Executive priority
Treat as a routine but time-bound WordPress plugin remediation item. Prioritize internet-facing WordPress sites, especially those handling sensitive content. The risk is moderate because exploitation is unauthenticated, but documented impact is limited to confidentiality.
Technical view
The issue is classified as CWE-862, Missing Authorization, in Iulia Cazan Latest Post Shortcode. CVSS 3.1 is 5.3 with AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating remotely reachable, low-complexity, unauthenticated exposure with limited confidentiality impact only.
Likely exposure
Exposure is limited to WordPress sites using Latest Post Shortcode versions up to and including 14.2.1. Sites not using this plugin are not affected based on the provided sources.
Exploitation context
The CVE is not listed as KEV in the provided data, and no cited source states active exploitation. The CVSS vector indicates exploitation would not require authentication or user interaction if the vulnerable plugin is reachable.
Researcher notes
Available public detail is sparse. The record identifies missing authorization and affected versions but does not provide a fixed version, detailed endpoint information, or evidence of exploitation. Avoid assuming broader impact beyond limited confidentiality without additional vendor data.
Mitigation direction
- Inventory WordPress sites for the Latest Post Shortcode plugin.
- Identify installed plugin versions and flag versions 14.2.1 or earlier.
- Check the plugin vendor or Patchstack page for current fix guidance.
- Update or disable the plugin if vendor guidance recommends it.
- Restrict unnecessary public exposure where operationally feasible.
Validation and detection
- Confirm whether the plugin is installed on each WordPress instance.
- Record the installed plugin version from WordPress administration or asset inventory.
- Compare installed versions against the affected range: through 14.2.1.
- Review web access logs for unusual unauthenticated requests to plugin-related paths.
- Monitor vendor, CVE, and Patchstack records for updated remediation details.
