Security readout for executives and security teams
Plain-English summary
CVE-2026-25459 is a medium-severity broken access control issue in the WordPress Sober theme by uixthemes, affecting versions up to and including 3.5.12. An authenticated user could perform an unauthorized action with limited integrity impact. No source provided indicates active exploitation.
Executive priority
Treat as a normal-priority remediation item for affected WordPress sites, with elevated urgency for e-commerce or membership sites that allow user accounts. The known impact is limited, but WordPress theme access-control flaws can create operational and trust risks.
Technical view
The CVE describes CWE-862 Missing Authorization in Sober for WordPress. CVSS 3.1 is 4.3: network-accessible, low complexity, low privileges required, no user interaction, unchanged scope, no confidentiality or availability impact, and low integrity impact. The public record does not specify the vulnerable endpoint, action, patch version, or detailed remediation.
Likely exposure
Exposure is limited to WordPress sites using the Sober theme at version 3.5.12 or earlier. Because exploitation requires low-privileged authentication, risk is higher on sites allowing customer, subscriber, contributor, or other untrusted user accounts.
Exploitation context
The issue is remotely reachable over the network and does not require user interaction, but it does require an authenticated low-privileged account. The sources do not report public exploitation, proof-of-concept availability, or inclusion in CISA KEV.
Researcher notes
Public details are sparse. The CVE and Patchstack entry identify missing authorization in Sober through 3.5.12, but do not provide the affected function, endpoint, fixed version, or exploit indicators in the supplied sources. Avoid assuming a patch exists without vendor confirmation.
Mitigation direction
- Inventory WordPress sites using the Sober theme.
- Identify any Sober installations at version 3.5.12 or earlier.
- Check uixthemes, WordPress theme, and Patchstack guidance for an update or mitigation.
- Restrict untrusted user registration where business operations allow.
- Review user roles and remove unnecessary low-privileged accounts.
Validation and detection
- Confirm the active theme and installed Sober version in WordPress administration.
- Check whether public registration or low-trust accounts are enabled.
- Review recent role, theme, and settings changes for unexpected modifications.
- Monitor vendor and vulnerability database entries for patch details.
