3 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: IPC handlers failed to adequately validate and restrict file reading operations, allowing arbitrary local file read access through directory traversal. Developers must enforce directory limits and strict extension checks.
Remote Code Execution: Using unsafe external URL handlers allowed arbitrary protocol execution (e.g., file: or jar:), leading to code execution. This required restricting schemes explicitly to http, https, and mailto.
Path Traversal: Percent-encoded traversal segments allowed escaping the wallpaper asset root directory during path resolution, highlighting the need for canonicalization before prefix checks.
