Stored XSS via malformed autocomplete sanitization
Published Jun 2, 2023 · Updated Jan 8, 2025
Stored XSS in Trilium Notes before 0.59.4 allows attackers to execute scripts when a user views a crafted autocomplete result. The search service passes a quoted regular-expression string to replace(), so angle and brace characters in note-path titles are not removed as intended. A victim must display an autocomplete result containing attacker-controlled markup, and the script can read or alter data available to that session.
