Security readout for executives and security teams
Plain-English summary
CVE-2026-2351 affects the WordPress Task Manager plugin through version 3.0.2. A logged-in user with Subscriber-level access or higher may be able to read files from the web server. This could expose configuration files, secrets, or other sensitive data. Public sources do not show known active exploitation.
Executive priority
Treat as a near-term remediation item for affected WordPress sites. The bug requires login access, reducing urgency versus unauthenticated flaws, but the potential exposure of secrets or configuration files can create follow-on compromise risk.
Technical view
The issue is an authenticated arbitrary file read in Task Manager’s callback_get_text_from_url() function, mapped to CWE-73. CVSS is 6.5, with network access, low complexity, low privileges, no user interaction, and high confidentiality impact. Integrity and availability are not scored as impacted.
Likely exposure
Exposure is likely limited to WordPress sites running Task Manager plugin versions up to and including 3.0.2, especially where untrusted users can authenticate as Subscribers or higher.
Exploitation context
An attacker needs a valid WordPress account with Subscriber-level privileges or above. The reported impact is reading arbitrary server-side files. The source bundle does not indicate unauthenticated exploitation, public weaponization, or CISA KEV listing.
Researcher notes
The public record identifies the vulnerable function and affected range but does not provide a named fixed version in the supplied bundle. Validate against the live WordPress plugin listing and vendor advisories before concluding remediation status. Avoid assuming exploitation beyond the authenticated arbitrary file read described.
Mitigation direction
- Inventory WordPress sites for the Task Manager plugin and installed version.
- If running version 3.0.2 or earlier, check WordPress or vendor guidance for a fixed release.
- Restrict or remove untrusted Subscriber-level accounts where the plugin remains installed.
- Disable the plugin if no fixed version is available and risk is unacceptable.
- Review server file permissions to limit sensitive files readable by the web process.
Validation and detection
- Confirm whether Task Manager is installed on each WordPress site.
- Record the plugin version and compare it with the affected range: up to 3.0.2.
- Review WordPress users with Subscriber-level access or higher.
- Check web and application logs for unusual plugin import or file retrieval activity.
- Monitor Wordfence, CVE, and WordPress plugin pages for update or exploitation status.
