CVE published 4 Nov 2026
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
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 3 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

A fix is available in VikWidgetsLoader version 1.12.3. Users should upgrade to version 1.12.3 or later to remediate this vulnerability. No other mitigation guidance is provided in the available data.

Description

The VikWidgetsLoader WordPress plugin versions before 1.12.3 contain a vulnerability where several block attributes are not properly sanitized or escaped before being output inside HTML attributes. This flaw allows users with the Contributor role to inject arbitrary JavaScript, which executes in the browsers of users viewing the affected posts, including administrators and editors who review submissions.

Impact

This vulnerability permits stored cross-site scripting (XSS) attacks by users with Contributor roles, allowing them to execute arbitrary JavaScript in the browsers of other users, including administrators and editors. This can lead to session hijacking, privilege escalation, or other malicious actions performed in the context of trusted users.

Summary

The VikWidgetsLoader WordPress plugin prior to version 1.12.3 fails to sanitize or escape multiple block attributes before rendering them within HTML attributes. This security weakness enables users with Contributor-level permissions to store arbitrary JavaScript code that executes in the context of any user viewing the affected post. This includes high-privilege users such as administrators and editors, potentially leading to cross-site scripting (XSS) attacks.
