Security readout for executives and security teams
Plain-English summary
A critical flaw in the Events Manager WordPress plugin before 7.4.1 can let an unauthenticated attacker take over, promote, or delete user accounts, including administrators, when a user ID matches an Events Manager post ID. Successful abuse could lead to complete website compromise, data exposure, content manipulation, and service disruption.
Executive priority
Treat this as an immediate remediation priority on public WordPress sites. Prioritize systems containing sensitive data, business-critical content, or privileged integrations. Because abuse may provide full administrative control without credentials, investigate potentially exposed installations for account tampering rather than assuming updating alone resolves prior compromise.
Technical view
The plugin improperly scopes WordPress capability mapping and overrides authorization decisions for unrelated privileged user operations. This CWE-269 flaw is remotely reachable without credentials or user interaction. Impact includes password changes, Administrator escalation, and account deletion. Exploitation depends on a target user ID matching an Events Manager post ID.
Likely exposure
Internet-accessible WordPress sites running Events Manager earlier than 7.4.1 are potentially exposed. The bundle specifically lists version 7.1, while its description broadly states versions before 7.4.1. Actual exploitability also requires the described user-ID and Events Manager post-ID match.
Exploitation context
The CVSS 3.1 score is 9.8, reflecting remote, low-complexity, unauthenticated impact without user interaction. The WPScan reference is tagged for exploitation information, but the supplied evidence does not establish active exploitation. This CVE is not identified as being in KEV.
Researcher notes
The key condition is an identifier collision between a WordPress user and an Events Manager post. Capability mapping then discards WordPress authorization decisions for unrelated account actions. The supplied bundle does not provide request details, proof-of-concept material, affected-version precision beyond “before 7.4.1,” or evidence of exploitation in the wild.
Mitigation direction
- Update Events Manager to version 7.4.1 or later after appropriate compatibility testing.
- Inventory all WordPress sites to locate affected Events Manager installations.
- Follow current plugin vendor guidance if updating immediately is not possible.
- Review administrator accounts and reset credentials where compromise is suspected.
Validation and detection
- Confirm the installed Events Manager version is 7.4.1 or later.
- Identify user IDs matching existing Events Manager post IDs.
- Review accounts for unexpected Administrator privileges, password changes, or deletions.
- Examine WordPress and hosting logs for suspicious unauthenticated account-management activity.
- Verify privileged user operations still enforce WordPress authorization after updating.

CWE-269: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCredential and access behavior lookup
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
