CVE-2024-39828Public exploitNetwork attack vector

Script execution via unescaped saved-game clone property

Published Jun 28, 2024 · Updated Aug 2, 2024

Cross-site scripting in R74n Sandboxels 1.9 through 1.9.5 allows attackers to execute JavaScript via a modified saved-game file. The hover-stat renderer concatenates a pixel's unvalidated clone property into the stats div as HTML when the pixel is hovered. A victim must load the crafted save and hover over the altered pixel, after which script runs in the Sandboxels page context.
