No public nuclei template indexed

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 30 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.

What to do

AI-suggested

Until a fix is available, restrict access to trusted users and monitor for suspicious activity related to URL inputs in the affected component.

Description

An authenticated cross-site scripting (XSS) vulnerability exists in Spina CMS version 2.21.0 in the /spina/embeddable.rb component. This flaw allows attackers with authentication to inject arbitrary web scripts or HTML via a crafted URL, potentially leading to script execution in the context of the affected application.

Impact

Successful exploitation allows an authenticated attacker to execute arbitrary scripts or HTML in the context of the vulnerable Spina CMS instance. This could lead to session hijacking, defacement, or other attacks leveraging the victim's browser context. The vulnerability requires authentication, limiting exposure to authorized users.

Summary

CVE-2026-117182 describes an authenticated XSS vulnerability in Spina CMS v2.21.0 specifically in the /spina/embeddable.rb component. Attackers who are authenticated can exploit this vulnerability by injecting malicious scripts or HTML through a crafted URL, which the application fails to properly sanitize or encode, resulting in arbitrary script execution.
