[ Reason ] node-dottie is vulnerable to prototype pollution (#1040592, CVE-2023-26132) [ Impact ] Medium security issue [ Tests ] Test updated passed [ Risks ] Low risk, patch is trivial [ Checklist ] [X] *all* changes are documented in the d/changelog [X] I reviewed all changes and I approve them [X] attach debdiff against the package in (old)stable [X] the issue is verified as fixed in unstable [ Changes ] Don't allow __proto__ modifications. Patch includes also debian/tests/pkg-js/enable_proto file to allow __proto__ calls during autopkgtest (forbidden by default) because patch includes a prototype-pollution test Cheers, Yadd
