Security readout for executives and security teams
Plain-English summary
CVE-2026-25311 is a medium-severity broken access control issue in the WordPress Autoshare for Twitter plugin by 10up, affecting versions through 2.3.1. A logged-in user with some privileges could perform actions they should not be authorized to perform. Sources do not indicate active exploitation or a confirmed patch version.
Executive priority
Treat as a normal vulnerability-management priority unless the site allows many user accounts or untrusted contributors. It is not currently supported as an emergency exploitation case by the provided sources, but affected public WordPress sites should still be inventoried and remediated promptly.
Technical view
The vulnerability is categorized as CWE-862, Missing Authorization. The CVSS 3.1 score is 5.4 with network attack vector, low complexity, privileges required, no user interaction, and low integrity and availability impact. The affected component is the WordPress plugin package autoshare-for-twitter through version 2.3.1.
Likely exposure
Exposure is limited to WordPress sites with Autoshare for Twitter installed at version 2.3.1 or earlier. The CVSS vector requires an authenticated user, so risk is higher on sites with many contributors, subscribers, authors, editors, or other delegated accounts.
Exploitation context
The provided sources do not report active exploitation, public exploit code, or CISA KEV listing. The issue appears exploitable over the network by a logged-in user and may allow unauthorized actions affecting site integrity or availability, depending on plugin configuration and user roles.
Researcher notes
The public record is sparse. The CVE description states missing authorization in Autoshare for Twitter through 2.3.1, while the CVSS vector indicates authenticated exploitation with low integrity and availability impact. No source in the bundle names a fixed release, workaround, exploit activity, or affected endpoint details.
Mitigation direction
- Inventory WordPress sites for the Autoshare for Twitter plugin.
- Identify installations running version 2.3.1 or earlier.
- Check 10up, WordPress.org, and Patchstack guidance for fixed versions or mitigations.
- Restrict WordPress account creation and review unnecessary user privileges.
- Disable the plugin temporarily if business use is not required.
Validation and detection
- Confirm plugin name and version from WordPress administrative inventory.
- Review WordPress users with contributor-level or higher access.
- Check web application logs for unusual authenticated plugin-related activity.
- Monitor Patchstack and CVE records for updated remediation details.
- Document whether the plugin is active, inactive, or removed.
