Technical description

A vulnerability was found in karakeep-app karakeep up to 0.32.0. The affected element is the function authorize of the file apps/web/server/auth.ts of the component Login Endpoint. The manipulation results in improper restriction of excessive authentication attempts. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is described as difficult. The exploit has been made public and could be used. Upgrading to version 0.33.0 is sufficient to fix this issue. The patch is identified as f7d042971d0d2bcc7119654830cf1eb93eabbf24. It is advisable to upgrade the affected component.

——0SiYuan versions before 3.7.4 contain an unthrottled brute-force vulnerability in the Publish Service Basic Auth implementation (PublishServiceTransport.RoundTrip() in kernel/server/proxy/publish.go). The Publish Service runs on a separate, unauthenticated-by-default listener (default TCP port 6808) and gates named publish-viewer accounts (Conf.Publish.Auth.Accounts) with Basic Auth that has no rate limiting, per-account lockout, or backoff. Unauthenticated remote attackers can submit unlimited password guesses against named accounts to gain access to published notes/notebooks.1d CVE-2026-730569.8 CRI

——11SiYuan kernel versions before 3.7.4 contain an improper restriction of excessive authentication attempts vulnerability in the CheckAuth() middleware. The middleware accepts the API token (Conf.Api.Token) via an Authorization header (Token/Bearer) or a ?token= query parameter, and neither path is protected by the application's CAPTCHA/lockout mechanism (NeedCaptcha/WrongAuthCount). As a result, an unauthenticated remote attacker can perform unlimited automated guesses of the API token, particularly when a short or weak custom token has been configured, and upon success gains full RoleAdministrator access enabling arbitrary file operations and SQL queries.1d CVE-2026-730469.8 CRI

——11SiYuan before v3.7.4 improperly restricts excessive authentication attempts in the CheckAuth() middleware. The HTTP Basic Authentication branch, which guards nearly the entire /api/* surface, accepts the workspace access code (Conf.AccessAuthCode) as the Basic Auth password but never consults the CAPTCHA/lockout gate or increments the failure counter used by the cookie/session login path. This allows unauthenticated remote attackers to brute-force the admin access code with unlimited automated requests and obtain full RoleAdministrator access to the kernel. A secondary weakness exists because the access code is compared using a non-constant-time string comparison.1d CVE-2026-730457.5 HIG

——7SiYuan before 3.7.4 contains an improper restriction of excessive authentication attempts vulnerability in the authFilePublishAccess endpoint that allows unauthenticated attackers to brute-force per-notebook publish passwords. Attackers can submit unbounded password guesses without rate limiting or CAPTCHA to gain access to password-protected published notebooks.1d CVE-2026-198983.7 LOW

——12A vulnerability was found in VictoriaMetrics up to 1.146.0. Impacted is the function requestHandler of the file app/vmauth/main.go of the component VMAuth Authentication Endpoint. Performing a manipulation results in improper restriction of excessive authentication attempts. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is considered difficult. The exploit has been made public and could be used. Upgrading to version 1.147.0 is recommended to address this issue. The patch is named 119ba0fb5be8024d50c5ba946599b2e69e8803ea. Upgrading the affected component is recommended.13h CVE-2026-198973.7 LOW

——9A vulnerability has been found in mangroup dtale up to 3.22.0. This issue affects the function Login of the file dtale/auth.py of the component Login Endpoint. Such manipulation leads to improper restriction of excessive authentication attempts. The attack can be executed remotely. This attack is characterized by high complexity. The exploitability is assessed as difficult. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.1d
