CVE-2022-39315: Getkirby Kirby

Medium severity, CVSS 5.3. EPSS: 0.7% chance of exploitation in the next 30 days.

Kirby is a Content Management System. Prior to versions 3.5.8.2, 3.6.6.2, 3.7.5.1, and 3.8.1, a user enumeration vulnerability affects all Kirby sites with user accounts unless Kirby's API and Panel are disabled in the config. It can only be exploited for targeted attacks because the attack does not scale to brute force. The problem has been patched in Kirby 3.5.8.2, Kirby 3.6.6.2, Kirby 3.7.5.1, and Kirby 3.8.1. In all of the mentioned releases, the maintainers have rewritten the affected code so that the delay is also inserted after the brute force limit is reached.

Affected products

• Getkirby Kirby: before 3.5.8.2 (fixed in 3.5.8.2); from 3.6.0, before 3.6.6.2 (fixed in 3.6.6.2); from 3.7.0, before 3.7.5.1 (fixed in 3.7.5.1); version 3.8.0 only
