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 11 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

Upgrade to Apache Roller version 6.1.7 or later, which fixes this vulnerability by enforcing stricter MIME type handling and disallowing user-controlled paths in media uploads. If upgrading is not immediately possible, disable media uploads or avoid using custom themes that allow this behavior.

Description

Apache Roller 6.1.6 contains a cross-site scripting (XSS) vulnerability that allows an authenticated user with Author role on a weblog using a custom theme to inject script code. This script runs in the browsers of anyone who accesses the affected file's resource URL. The issue arises because media files uploaded via a custom theme were served with a MIME type based on their path, which the uploader could control. Media uploads are disabled by default. The vulnerability is fixed in Apache Roller 6.1.7 and later, which serve these files under stricter rules and no longer accept the path from the upload form.

Impact

An authenticated Author user can inject malicious scripts that execute in the browsers of other users who visit the affected resource URLs, potentially leading to session hijacking, data theft, or other client-side attacks. The vulnerability requires authentication and use of a custom theme. Media uploads are disabled by default, reducing exposure. No known exploits in the wild have been reported.

Summary

CVE-2026-111824 describes an improper neutralization of input during web page generation (cross-site scripting) in Apache Roller version 6.1.6. An authenticated user with the Author role on a weblog that uses a custom theme can upload media files with a chosen path that influences the MIME type served. Because the server serves these files with the MIME type implied by the path, malicious script can be stored and executed in the browsers of users who open the resource URL. The fix introduced in version 6.1.7 aligns the handling of these files with other media files by restricting MIME types and disallowing path control from the upload form, mitigating the XSS risk.

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.
