VLAI?
Summary
Path traversal and code execution via prototype vulnerability
Details

Impact

Due to the use of the object destructuring assignment syntax in the user export code path, combined with a path traversal vulnerability, a specially crafted payload could invoke the user export logic to arbitrarily execute javascript files on the local disk.

Patches

Patched in v2.8.7

Workarounds

Site maintainers can cherry pick ec58700f6dff8e5b4af1544f6205ec362b593092 into their codebase to patch the exploit.
