Summary

CVE-2026-24769 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Nocodb Nocodb. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 32th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-24769 is a stored cross-site scripting (XSS) vulnerability in NocoDB, an open-source software platform for building databases as spreadsheets. The issue resides in the attachment handling mechanism and affects versions prior to 0.301.0. It allows authenticated users to upload malicious SVG files containing embedded JavaScript, which are stored server-side and rendered inline when viewed by other users, leading to arbitrary code execution in the victims' browsers under the application's origin. The vulnerability is associated with CWE-79 (Cross-Site Scripting) and CWE-434 (Unrestricted Upload of File with Dangerous Type), earning a CVSS v3.1 base score of 9.0 (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H).

An attacker with low-privilege authenticated access (PR:L) can exploit this by uploading a specially crafted SVG attachment to a shared resource. When other users, potentially with higher privileges, view the attachment, the embedded JavaScript executes in their browser context. This enables severe impacts including account takeover, data exfiltration from the application, and unauthorized actions performed on behalf of the victim, such as modifying records or escalating privileges, due to the cross-origin resource sharing (S:C) scope change.

The official patch is available in NocoDB version 0.301.0, which addresses the insecure rendering of SVG attachments. Additional details and remediation guidance are provided in the GitHub Security Advisory at https://github.com/nocodb/nocodb/security/advisories/GHSA-q5c6-h22r-qpwr, published on 2026-01-28. Security practitioners should upgrade affected instances immediately and review attachment upload policies as an interim measure.

Vulnerability Data

NocoDB is software for building databases as spreadsheets. Prior to version 0.301.0, a stored cross-site scripting (XSS) vulnerability exists in NocoDB’s attachment handling mechanism. Authenticated users can upload malicious SVG files containing embedded JavaScript, which are later rendered inline and…

executed in the browsers of other users who view the attachment. Because the malicious payload is stored server-side and executed under the application’s origin, successful exploitation can lead to account compromise, data exfiltration and unauthorized actions performed on behalf of affected users. Version 0.301.0 patches the issue.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect input neutralization through targeted web-application tests.

Input validation directly enforces neutralization of untrusted data before it reaches web output generation.

Output filtering can catch or sanitize unneutralized script content before it is served to users.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

finds

Secure-coding testing and automated code-analysis tools are applied to detect improper neutralization of script-related content during web-page generation.

prevents

Knowledge exchange on emerging attack techniques and patches reduces the likelihood that cross-site scripting flaws remain unaddressed in deployed applications.

prevents

Operational indicators of compromise for web-application attacks can be incorporated into WAF or input-filtering rules, lowering the likelihood that unsanitized data reaches the browser.

prevents

Requiring language-specific secure-coding standards and automated scanning during the SDLC catches missing output encoding or improper neutralization of untrusted data before the software reaches production.

prevents

Secure-coding standards, SAST scans and removal of insecure code samples together eliminate the failure to neutralize script content that produces cross-site scripting flaws.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.
