Go: Interpretation Conflict

CVE-2022-23773 is a high-severity interpretation conflict vulnerability in Go, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 1.16.14, 1.17.7 as the first without the flaw, so updating Go to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.68% chance of exploitation within 30 days, higher than 86% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Go to 1.16.14 or 1.17.7, whichever matches your release line, or a later version.
  2. Read the advisory on groups.google.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

cmd/go in Go before 1.16.14 and 1.17.x before 1.17.7 can misinterpret branch names that falsely appear to be version tags. This can lead to incorrect access control if an actor is supposed to be able to create branches but not tags.

The underlying weakness: Interpretation Conflict

Product A handles inputs or steps differently than Product B, which causes A to perform incorrect actions based on its perception of B's state.
