Landscape: Exposure of Resource to Wrong Sphere
CVE-2023-32550 is a high-severity exposure of resource to wrong sphere vulnerability in Landscape from Canonical, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 19.10.05 as the first without the flaw, so updating Landscape to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.45% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do

- Read the advisory on bugs.launchpad.net for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
