AnalysisAIv1 – Sep 15, 2026

Authenticated privilege escalation in the Consulting WordPress theme (versions up to and including 6.7.16) lets any subscriber-level user take over a site as administrator by chaining two coding flaws. The theme's masterstudy_ms_stm_set_discard_transient AJAX action writes an attacker-chosen transient value without any capability check or nonce, and the theme's "developer access" login path trusts a transient value in legacy string mode, so an attacker can seed a known token and then log in as any existing account, including an admin. The CVSS score is 8.8 (network, low privileges, no user interaction, full confidentiality/integrity/availability impact); no EPSS score, KEV listing, or public exploit code was provided at time of analysis.

DescriptionCVE.org

The Consulting theme for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 6.7.16. This is due to a combination of two flaws: (1) the masterstudy_ms_stm_set_discard_transient AJAX endpoint in admin/admin-notices/classes/STMHandler.php accepts an arbitrary transient key without capability checks or nonce validation, and (2) the developer access login mechanism in admin/classes/stm-theme-support.php authenticates users based on a transient value without proper cryptographic validation when in legacy string mode. This makes it possible for authenticated attackers, with subscriber-level access and above, to set the stm_developer_access_token transient to a known value (1), then authenticate as any existing user including administrators by visiting a specially crafted URL, thereby achieving full privilege escalation to administrator.

News We need answer only title. Need include format "N New [Product] Vulnerabilities - X Critical, Y With POC". Here total 6, product WordPress, severity high all 6, no critical, POC 0. Title: "6 New WordPress Vulnerabilities - 0 Critical, 0 With POC". But X Critical is 0 maybe weird. Example format. Max 100. Could say "6 New WordPress Vulnerabilities - 0 Critical, 0 With POC". That's 57 chars. Ensure no quotes. Return only title. But maybe if no Sep 15, 2026

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
