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 29 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.
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

Upgrade the Contact Form by Supsystic WordPress plugin to version 1.11.1 or later, where the CSRF nonce verification before saving mail settings is implemented. If you cannot patch yet, avoid visiting untrusted or suspicious pages while logged in as an administrator to reduce the risk of CSRF exploitation.

Description

The Contact Form by Supsystic WordPress plugin versions before 1.11.1 lack verification of a CSRF nonce when saving mail settings. This vulnerability allows an attacker to trick a logged-in administrator into visiting a crafted page, resulting in the overwriting of the site's outbound mail configuration, including SMTP server details, credentials, and notification recipients. This can enable the attacker to route contact form notifications through infrastructure they control.

Impact

An attacker can manipulate the outbound mail configuration of the affected WordPress plugin by exploiting the lack of CSRF nonce verification. This can lead to unauthorized modification of SMTP server settings and notification recipients, allowing interception or redirection of contact form emails. The impact is limited to the mail configuration and does not indicate direct code execution or data breach beyond mail routing.

Summary

The Contact Form by Supsystic WordPress plugin prior to version 1.11.1 does not verify a CSRF nonce before saving its mail settings. This security flaw permits an attacker to perform a Cross-Site Request Forgery (CSRF) attack by deceiving an authenticated administrator into visiting a malicious page. Consequently, the attacker can overwrite the outbound mail configuration parameters such as SMTP server, credentials, and notification recipient addresses, potentially redirecting contact form notifications through attacker-controlled infrastructure.
