causefx/organizr: Integer Underflow (Wrap or Wraparound)
CVE-2022-1698 is a high-severity integer underflow (wrap or wraparound) vulnerability in causefx/organizr from Causefx, 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 version 2.1.2000 as the first without the flaw, so updating causefx/organizr to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.09% chance of exploitation within 30 days, higher than 66% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update causefx/organizr to 2.1.2000 or a later version.
- Update Organizr to 2.1.2000 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
