See : vuepress-theme-hope/vuepress-theme-hope#5262

Better raise the range to skip vulnerable versions.

I've already bumped the dependency version for the next release. This is a denial of service attack that someone could mount against themselves (by adding a problematic TOML file to their own repo or scanning a malicious one) and therefore does not seem particularly alarming.
