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

If you cannot patch yet, users should consider applying input validation and output encoding controls where possible to mitigate XSS risks.

Description

A Cross-Site Scripting (XSS) vulnerability exists in the Drupal AI (Artificial Intelligence) component due to improper neutralization of input during web page generation. This vulnerability affects versions from 0.0.0 to 1.4.11 and from 1.5.0 to 1.5.2 of the Drupal AI module. The flaw allows injection of malicious scripts into web pages, potentially leading to client-side code execution in users' browsers.

Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to session hijacking, defacement, or redirection to malicious sites. However, no active exploitation has been reported, and the exact impact depends on the deployment context of the Drupal AI module.

Summary

The vulnerability identified as CVE-2026-118549 is a Cross-Site Scripting (XSS) issue in the Drupal AI module. It arises from improper neutralization of input during web page generation, enabling attackers to inject malicious scripts. The affected versions include all releases from 0.0.0 up to 1.4.11 and from 1.5.0 through 1.5.2. No CVSS score or detailed exploit information is provided, and no known exploits in the wild have been reported. The vulnerability is classified under CWE-79.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
