CVE-2026-119715 in NocoDB
Summary
by MITRE • 10/30/2026
NocoDB before 2026.08.0 contains a clickjacking vulnerability that allows any origin to frame the authenticated interface because no X-Frame-Options or CSP frame-ancestors headers are sent. Attackers can overlay a signed-in user's session from a malicious page, tricking clicks that modify or delete records, change sharing settings, or invite collaborators.

NocoDB versions prior to the 2026.08.0 release exhibit a significant security flaw classified as clickjacking due to the absence of essential browser-side protection headers. This vulnerability stems from the application's failure to implement X-Frame-Options or Content-Security-Policy frame-ancestors directives, which are standard mechanisms designed to prevent web pages from being embedded within frames on other domains. By omitting these controls, NocoDB inadvertently allows any origin to load its authenticated interface inside an iframe, thereby enabling malicious actors to overlay the legitimate application with deceptive user interfaces that mimic authentic actions while operating under a different domain context.
The technical mechanism of this exploit relies on social engineering combined with browser behavior regarding cross-origin framing. An attacker can host a webpage containing an invisible or visually disguised iframe pointing to the NocoDB instance where a victim is currently authenticated. Because there are no headers restricting frame ancestry, modern browsers will successfully load the NocoDB interface within that malicious container without issuing any security warnings. The attacker then positions transparent elements over critical interactive components such as delete buttons, share settings toggles, or collaborator invitation fields. When an unsuspecting user interacts with the page believing they are clicking on a benign element of the overlaying content, their clicks are actually registered by the underlying NocoDB interface, effectively hijacking the user's session and intent.
The operational impact of this vulnerability is severe as it directly compromises the integrity and confidentiality of data managed within the NocoDB instance. An attacker can trick users into performing destructive actions such as deleting critical records or modifying database schemas without their knowledge. Furthermore, the ability to alter sharing settings allows an adversary to grant access to unauthorized parties, potentially leading to widespread data exposure. The invitation of collaborators represents another vector for persistent compromise, as it grants long-term access that persists even after the initial attack session concludes. This undermines the trust model of the application and poses significant risks to organizations relying on NocoDB for structured data management and collaboration.
From a classification perspective, this vulnerability aligns with CWE-1021 Improper Restriction of Rendered UI Layers or Frames, which describes scenarios where an attacker can trick users into interacting with hidden interfaces. In the context of the MITRE ATT&CK framework, this technique falls under Tactic TA0005 Defense Evasion and specifically Technique T1647 Phishing for Information from User Interface Elements, as it involves deceiving a user through visual manipulation to execute unintended commands. The lack of proper header configuration also relates to CWE-346 Origin Validation Error in the context of frame ancestry checks.
To mitigate this vulnerability, administrators must ensure that NocoDB instances are updated to version 2026.08.0 or later where these protections have been implemented by default. For environments running older versions, immediate remediation requires configuring the web server or reverse proxy hosting the application to include strict security headers. Specifically, setting X-Frame-Options to DENY or SAMEORIGIN prevents framing from external domains, while adding Content-Security-Policy with frame-ancestors 'self' provides a more granular and robust control mechanism that is widely supported by modern browsers. These measures effectively neutralize the clickjacking attack vector by instructing compliant user agents not to render the application content within frames originating from unauthorized sources.
