[ Reason ]
node-dottie is vulnerable to prototype pollution (#1040592,
CVE-2023-26132)
By all means go ahead, but it can't be accepted until the situation

bookworm-proposed-updates to testing).
The provided diff appears to be against the package in bookworm.
bullseye has 2.0.2-1.
Euf, right - sorry (too many releases started 'b'...)
Please revise the debdiff.
Thanks,
Sorry, here is the new debdiff
