Security readout for executives and security teams
Plain-English summary
CVE-2026-24636 is a medium-severity access control issue in the WordPress Sugar Calendar (Lite) plugin. A logged-in user may be able to perform an action they should not be authorized to perform. The published CVSS score is 4.3, indicating limited integrity impact and no stated confidentiality or availability impact.
Executive priority
Treat as a routine but timely WordPress plugin remediation. Prioritize sites with public registration, customer logins, or many low-privileged users. There is no source-backed evidence of active exploitation in the provided materials.
Technical view
The CVE describes CWE-862 Missing Authorization in Syed Balkhi Sugar Calendar (Lite), package sugar-calendar-lite, affecting versions through <= 3.9.1 per the CVE data. CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, meaning network-accessible exploitation by an authenticated low-privileged user with limited integrity impact.
Likely exposure
Exposure is likely limited to WordPress sites that have Sugar Calendar (Lite) installed, especially where untrusted or low-privileged users can log in. Public sources do not indicate impact to sites without the plugin or to unauthenticated visitors.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability requires prior login, lowering broad internet risk, but it may matter on sites with many subscribers, contributors, customers, or other low-privileged accounts.
Researcher notes
There is a version-detail inconsistency: the CVE data states affected through <= 3.9.1, while the Patchstack reference URL slug mentions 3.10.1. The provided bundle does not name a fixed version or describe the vulnerable function, so validation should rely on vendor/Patchstack details.
Mitigation direction
- Inventory WordPress sites for the Sugar Calendar (Lite) plugin and installed version.
- Check the vendor, WordPress plugin page, or Patchstack for the confirmed fixed version.
- Apply the vendor-recommended update or mitigation when confirmed.
- Restrict or review low-privileged user accounts on affected sites.
- Use least-privilege roles and remove unnecessary WordPress accounts.
Validation and detection
- Confirm whether sugar-calendar-lite is installed on each WordPress site.
- Record the installed plugin version and compare with affected versions.
- Review vendor and Patchstack advisories for fixed-version details.
- Check logs for unexpected authenticated changes involving calendar functionality.
- Verify role permissions for subscribers, contributors, and other low-privileged users.
