Penpot is an open-source design and prototyping platform. Prior to 2.18.0, authenticated users with file-edit permission can upload SVG media whose scripts, event-handler attributes, and foreignObject elements are stored without sanitization and served as image/svg+xml from the Penpot origin. A victim who navigates to the asset URL executes attacker-controlled JavaScript in that origin, allowing requests and data access with the victim's Penpot session authority. This issue is fixed in version 2.18.0.
CVE-2026-105694

EchelonGraph scoreLOW confidence
This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
