Package	Ecosystem	Affected	Fixed in
github.com/bablilayoub/openhole	Go	<0.1.2	0.1.2

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

openhole, a Go package, has a path traversal flaw in versions before 0.1.2: openhole-server passed the URL-decoded request path to tunnel clients, so percent-encoded dot-segments and slashes reached local services as traversal sequences. An unauthenticated remote attacker can read files outside the web root on tunneled services that do not canonicalize paths. Upgrade openhole and openhole-server to 0.1.2 or later, since both components need the fix.
