Detectable: no evidence on record.
No public nuclei template indexed

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 6 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

AI-suggested

If you cannot patch yet, restrict authenticated user roles and monitor plugin updates closely.

Description

The iLeads SMS Gateway WordPress plugin before version 2.0.0 contains a vulnerability where several AJAX actions do not verify user capabilities or nonces. This flaw allows any authenticated user, including low-privileged roles such as subscribers, to modify arbitrary WordPress site options. An attacker can exploit this to escalate privileges to administrator, for example by enabling user registration with the administrator role as default.

Impact

Any authenticated user, including subscribers, can exploit this vulnerability to escalate their privileges to administrator by modifying site options. This compromises the integrity and security of the WordPress site, potentially allowing full administrative control to unauthorized users.

Summary

The iLeads SMS Gateway plugin for WordPress versions prior to 2.0.0 fails to perform capability and nonce checks on multiple AJAX endpoints that update site options. This lack of proper authorization validation enables any authenticated user to change critical WordPress options arbitrarily. Such unauthorized changes can lead to privilege escalation, allowing a low-privileged user to gain administrator access by manipulating settings like the default user role upon registration.
