Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Royal MCP (WordPress plugin) to 1.5.10.

Affected software

Product	Affected	Fixed in
Royal MCP	Affected >=1.4.38 <1.5.10	Fixed in 1.5.10

AI-suggested

Upgrade the Royal MCP WordPress plugin to version 1.5.10 or later, where the authorization checks have been properly implemented to prevent unauthorized disclosure of non-public content.

Description

The Royal MCP WordPress plugin versions from 1.4.38 up to but not including 1.5.10 contain an authorization flaw in one of its search tools. This flaw allows authenticated users with low privileges, such as subscribers, to access the title and content of non-public entries, potentially exposing personal data stored by the plugin. The issue is resolved in version 1.5.10.

Impact

Authenticated users with subscriber-level privileges can access sensitive information from non-public entries, including personal data, which violates data confidentiality and privacy expectations. There is no indication of active exploitation in the wild.

Summary

CVE-2026-111960 describes an incorrect authorization vulnerability (CWE-863) in the Royal MCP WordPress plugin before version 1.5.10. The plugin fails to perform proper object-level or post-type authorization checks in a search tool, enabling authenticated users with minimal privileges to disclose titles and contents of non-public posts, including personal data managed by the plugin. This vulnerability affects versions >=1.4.38 and <1.5.10 and is fixed in version 1.5.10.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #17OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
