Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Github.com/usememos/memos, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

usememos/memos is an open-source, self-hosted memo hub with knowledge management and socialization. Memos prior to 0.9.0 has a feature to upload file and display it, and by uploading a crafted SVG file, an attacker could perform a stored cross-site scripting attack with the image direct link. This was patched in version 0.9.0.
