Samuel Gross discovered that processing maliciously crafted web content may lead to code execution

CVE-2021-42762

An anonymous reporter discovered a limited Bubblewrap sandbox bypass that allows a sandboxed process to trick host processes into thinking the sandboxed process is not confined.

For the stable distribution (bullseye), these problems have been fixed in version 2.34.1-1~deb11u1.

We recommend that you upgrade your wpewebkit packages.

For the detailed security status of wpewebkit please refer to its security tracker page at: [link moved to references]");
