CVE-2022-3945Network attack vector

Brute-force access via unrestricted login attempts

Published Nov 11, 2022 · Updated Apr 30, 2025

Improper restriction of authentication attempts in Kareadita Kavita before 0.6.0.3 allows remote attackers to guess passwords via repeated login requests. The login endpoint lacked effective limits on failed authentication attempts, allowing repeated guesses against accounts. Unauthenticated remote attackers can continue retries until a password is guessed, resulting in account compromise; no broader impact is documented.
