CVE-2026-69183 1 Monkeytype 1 Monkeytype 2026-08-21 7.5 High
Monkeytype is a minimalistic and customizable typing test. In 26.26.0 and earlier, the backend rate-limit key generator in backend/src/middlewares/rate-limit.ts uses client-controlled cf-connecting-ip and x-forwarded-for headers before the trust-proxy-derived req.ip value. An unauthenticated attacker can rotate either header to create a new bucket for each request, bypassing rootRateLimiter, badAuthRateLimiter, getKey(), and the getKeyWithUid() fallback used by public endpoints. This permits repeated POST /users/forgotPasswordEmail and verificationEmail requests, mail bombing registered users, consuming Firebase or SMTP quota, evading brute-force protection, and enabling resource exhaustion. Exploitability of cf-connecting-ip depends on deployment topology, but x-forwarded-for and direct-to-origin paths remain affected when those values are not overwritten by a trusted proxy. No fixed version is available as of this review.
CVE-2026-76213 1 Phpmyfaq 1 Phpmyfaq 2026-08-19 7.4 High
phpMyFAQ before 4.1.7 contains a brute-force vulnerability in the two-factor authentication step where the failure counter is session-scoped and reset on each successful password re-authentication. Attackers with a valid password can bypass the five-attempt limit by obtaining a fresh session cookie and repeatedly re-authenticating to reset the counter, enabling unbounded TOTP code guessing.
CVE-2026-73529 1 Alextselegidis 1 Plainpad 2026-08-18 5.3 Medium
Plainpad through 1.1.1, fixed in commit d3823fc, contains a missing rate limiting vulnerability that allows unauthenticated attackers to send unbounded login requests to the POST /v1/sessions endpoint due to dead code in App\Http\Kernel.php that is never instantiated under the Laravel 11+ skeleton, leaving the API throttle configuration unattached to any route. Attackers can exploit this by sending unlimited credential attempts with no lockout or CAPTCHA enforcement, and additionally trigger CPU exhaustion by forcing repeated bcrypt comparisons on each request.
CVE-2026-75773 1 Karakeep-app 1 Karakeep 2026-08-18 3.7 Low
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.
CVE-2026-73045 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-08-18 7.5 High
SiYuan 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.
CVE-2026-73056 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-08-17 9.8 Critical
SiYuan 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.
CVE-2026-65948 1 Apache 1 Ranger 2026-08-17 7.3 High
UnixAuth lacks brute-force protection in Apache Ranger versions <= 2.8.0.  Note:  UnixAuth is NOT a recommended option for production deployments.  Users are recommended to upgrade to version 2.9.0, which fixes this issue.
CVE-2026-19895 1 Opensourcepos 1 Open Source Point Of Sale 2026-08-17 3.7 Low
A vulnerability was detected in opensourcepos Open Source Point of Sale up to 3.4.2. This affects the function Login::index of the file app/Config/Filters.php of the component Login Endpoint. The manipulation results in improper restriction of excessive authentication attempts. The attack may be launched remotely. The attack requires a high level of complexity. It is indicated that the exploitability is difficult. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-74868 1 B3log 1 Siyuan 2026-08-17 7.5 High
SiYuan 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.
CVE-2026-73046 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-08-17 9.8 Critical
SiYuan 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.

CVE-2026-48071 1 Open-reception 1 Appointment-booking-software 2026-08-08 5.8 Medium
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.4, the PIN-type challenge throttle uses `emailHash` as the only key. The throttle rows live in the central `challenge_throttle` table, which is shared across all tenants. Every tenant's `/api/tenants/{id}/appointments/verify-challenge` endpoint increments the same row when a PIN response fails, and every tenant's `/api/tenants/{id}/appointments/challenge` endpoint reads the same row when deciding whether to issue a new challenge. When the same `emailHash` exists in multiple tenants on the same OpenReception instance (the same patient holding tunnels in two different clinics that share the platform), an attacker who knows the patient's email can lock out that patient on tenant B by issuing failed challenge responses against tenant A. The attacker needs no relationship to tenant B; the lockout propagates through the shared throttle row. The lockout escalates with repeated failures. The first lockout triggers at 4 failed attempts and lasts approximately 60 seconds. Subsequent failures escalate the lockout duration to 5 minutes, 30 minutes, and 60 minutes per the throttle service's escalation logic. Repeated bursts produce sustained denial of service against the targeted email. Version 1.0.4 patches the issue.
