traQ is a messenger application built for Digital Creators Club traP. Prior to 3.28.3, instances configured with TRAQ_STORAGE_TYPE=local can return user-uploaded SVG or HTML content from the /files/{fileId} retrieval endpoint for direct browser rendering. An attacker with file-upload capability can provide crafted active content and induce another user to open its file URL, causing attacker-controlled JavaScript to execute in the victim's browser. This issue is fixed in version 3.28.3.
CVSS 7.3 (HIGH)

Evidence context and dated references

Reality is general threat/review priority, combining observed exploitation, CVSS severity and fresh EPSS. Evidence confidence is separate. This is not calibrated risk, a victim count or an asset-specific assessment. A range reflects missing numeric inputs. Published 4 days ago. Exploitation evidence usually takes weeks to show up: a low reality score can mean there is no data yet, not that the flaw is mild.
