Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Detectable: no evidence on record.

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.

AI-suggested

Organizations should upgrade HCL Nomad server on Domino to version 1.0.19 or later once the vendor releases a patch that properly configures the frame-ancestors directive in the CSP header. Until then, administrators can manually configure web server or reverse proxy settings to include a strict Content-Security-Policy header with frame-ancestors directives limiting framing to trusted domains only. For example, setting 'Content-Security-Policy: frame-ancestors 'self'' restricts framing to the same origin. Additionally, implementing X-Frame-Options headers as a fallback can help mitigate framing risks in older browsers. Security teams should audit their web application security headers regularly and conduct penetration testing to verify the effectiveness of these controls. User education about phishing and clickjacking risks can reduce the likelihood of successful exploitation. Monitoring web traffic for suspicious framing attempts and employing browser security features like frame busting scripts may provide additional layers of defense.

Description

HCL Nomad server on Domino did not configure the frame-ancestors directive in the Content-Security-Policy header by default which could allow an attacker to obtain sensitive information via unspecified vectors.

Impact

The primary impact of this vulnerability is a potential confidentiality breach through UI embedding attacks such as clickjacking or frame-based information leakage. Attackers could exploit this to trick users into revealing sensitive information or perform unauthorized actions by overlaying malicious content. However, the lack of integrity or availability impact and the high attack complexity reduce the overall risk. Organizations with sensitive data accessible via HCL Nomad server on Domino could face targeted attacks aiming to harvest credentials or confidential information. The vulnerability could also facilitate social engineering attacks by framing legitimate content within attacker-controlled pages. While no exploits are known in the wild, the exposure of this weakness increases the attack surface and could be leveraged in multi-stage attacks. Enterprises relying on this software for remote access to Domino applications should consider the risk in their threat models, especially where users access the service from untrusted networks or browsers.

CWE-1021Improper Restriction of Rendered UI Layers or Frames (opens in a new tab)
Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.
Implementation
Use the "frame-ancestors" directive in the Content Security Policy, which is intended to define restrictions when it comes to allowing embedded content.
Implementation
The use of X-Frame-Options (now partially obsolete as of September 2026) allows developers of web content to restrict the usage of their application within the form of overlays, frames, or iFrames. The developer can indicate from which domains can frame the content.
Implementation
Use a "frame-breaker" script in each page that should not be framed. This is very helpful for legacy browsers that do not support the X-Frame-Options security feature previously mentioned (which is now partially obsolete).
