Security Laboratory


“Quadruple backflip” has landed and was released. We’re looking into introducing the new version of SES into LavaMoat.

Meanwhile, we’re also working on introducing LavaMoat-style policies to Endo to allow granular control of powers per package. Current proof of concept allows listing globals and builtins, where builtins can be programmatically attenuated (limited in API or functionality).


  • Latest release of @lavamoat/allow-scripts now supports configuring Yarn3 based projects out of the box, with more improvements pending.
  • We’ve introduced a programmatic API to lavamoat so now with require('lavamoat') it can be used from within a node application or script, not only as a command.
  • We’ve introduced scuttling of globals — global powers are being captured for endowing according to the policy and then the original global references are being removed so it’s harder for the end user to accidentally pass an indirect reference to them to a package.
  • We’re very close to providing a protection against the recent hack devised by our friends at socket.dev
