Logseq sandbox escape via plugin HTML attribute injection
Logseq is affected by a sandbox escape vulnerability in which plugins running inside sandboxed iframes can inject arbitrary HTML attributes, including JavaScript event-handler attributes, into their container element in the host DOM. Because Content Security Policy protections are disabled, those injected attributes can be used to execute arbitrary JavaScript in the privileged host context rather than remaining confined to the sandboxed plugin frame. The issue was reported as affecting Logseq through version 0.10.15; the provided content states that v0.10.15 was tested and confirmed vulnerable, while the status of other versions is unknown because no patch had addressed the issue.
