Seatd: Exposure of Resource to Wrong Sphere
CVE-2022-25643 is a critical-severity exposure of resource to wrong sphere vulnerability in Seatd from Seatd Project, with a CVSS 3.1 base score of 9.8 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 0.6.4 as the first without the flaw, so updating Seatd to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.1% chance of exploitation within 30 days, higher than 82% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Seatd to 0.6.4 or a later version.
