When building the project locally I get these errors:
This happens because the first parameter to
console.error()
is a format string that can accept printf-like placeholders like%s
. Using non-literal values to build this value is unsafe. For example,tag
is an untrusted value that is obtained fromargv
. If we were to craft a value fortag
that includes a placeholder such as%O
, then we could force the program to dump the internals of the other parameters being passed toconsole.error()
.This PR addresses this issue by inserting a hard-coded literal
'%s %o'
for the format string.This is actually a point of confusion with
console.log()
and friends, because:See
util.format()
for details.
