Description

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, with NC_SECURE_ATTACHMENTS=true, an authenticated uploader could deliver .html or .svg attachments that the browser rendered inline from the NocoDB origin instead of forcing a download. The signed attachment handler stored response-header overrides under PascalCase keys (ResponseContentDisposition, ResponseContentType) while the controller that served the file read them under lowercase-hyphen names (response-content-disposition). The mismatch dropped the Content-Disposition: attachment header, leaving Express to auto-render .html, .svg, and similar inline. This vulnerability is fixed in 2026.05.1.
