What is CVE-2026-53841?

OpenClaw prior to version 2026.5.12 contains a cross-site scripting vulnerability that can be exploited through exported session HTML. This weakness allows attackers to embed unsafe JavaScript and data links in the generated content. If a user with trusted access opens the exported file and interacts with a malicious link, it may lead to execution of unauthorized scripts, thereby jeopardizing the user's browser environment. Users are advised to update to the latest version to mitigate this risk.
