Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB

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 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

A fixed version 4.3.14 or later of the User Frontend WordPress plugin addresses this vulnerability. Users should upgrade to version 4.3.14 or later to remediate this issue. No other mitigation guidance is provided, and no indication exists that the vulnerability is already mitigated or requires no action.

Description

The User Frontend WordPress plugin versions before 4.3.14 contain a reflected cross-site scripting (XSS) vulnerability. This occurs because some user-supplied values are not properly sanitized or escaped before being reflected in HTML attributes in an AJAX response accessible to the public. The vulnerable action is protected by a nonce that only validates for logged-out users, so the XSS payload executes against visitors who are not authenticated.

Impact

Reflected cross-site scripting allows an attacker to inject malicious scripts that execute in the browsers of logged-out visitors to the affected WordPress site. This can lead to theft of sensitive information, session hijacking, or redirection to malicious sites for those visitors. Authenticated users are not directly impacted by this vulnerability due to the nonce validation restricting the attack to logged-out users.
