9Router has a Login Brute-Force Lockout Bypass via Spoofable X-9r-Real-Ip Header

Summary 9router enforces a progressive login lockout 5 failed attempts → temporary 30s+ lock keyed on the client IP. The client IP used for this limiter is taken from the X-9r-Real-Ip request header, which is intended to be set only by the bundled custom-server.js layer from the unspoofable TCP...

9Router is an AI router & token saver. Prior to 0.5.6, 9Router deployments that allow requests to reach Next.js without the sanitizing custom-server.js wrapper use the client-supplied X-9r-Real-Ip value as the bucket key in getClientIp, checkLock, and recordFail in src/lib/auth/loginLimiter.js fo...

CVE-2026-92583: Improper Restriction of Excessive Authentication Attempts

AVideo through 29.0 contains a race condition in the enforceRateLimit function that fails to atomically increment rate limit counters, allowing attackers to bypass all rate limits including login brute-force protection by issuing concurrent requests. Attackers can submit parallel credential...

CVE-2026-86186 AVideo API Rate Limit Bypass via Bot User-Agent Header

AVideo API fails to enforce rate limits when clients send a bot User-Agent header, allowing attackers to bypass all eight protected operations including login brute-force protection. Attackers can send requests with a bot User-Agent to disable rate limiting and perform unlimited password guessing...

CVE-2026-73529

Plainpad (≤1.1.1) has dead code in App\Http\Kernel.php under the Laravel 11+ skeleton, leaving the throttle config unattached to POST /v1/sessions, allowing unlimited unauthenticated credential attempts and CPU exhaustion via bcrypt comparisons. Fixed in commit d3823fc595b5d8f842a6fd7dfe49b7852a1...

CVE-2026-73529 Plainpad Missing Rate Limiting via POST /v1/sessions

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+ skeleto...

EUVD-2026-42517

Use of a cryptographically weak random number generator in the GenerateRandomPassword function in bosh-windows-stemcell-builder allows a remote attacker to brute-force the resulting SSH login via TCP/22. Affected versions: bosh-windows-stemcell-builder versions prior to v2019.98...

GHSA-7CFM-PQRJ-XGQ7 9router: Login brute-force protection bypass via spoofed X-Forwarded-For header

Summary The 9router dashboard login rate limiter derives the client identity from the attacker-controlled X-Forwarded-For HTTP header. When 9router is directly exposed, or deployed behind a reverse proxy that does not overwrite untrusted forwarding headers, a remote attacker can rotate the...

CVE-2026-46356

Fleet is open source device management software. Prior to version 4.80.1, a vulnerability in Fleet's IP extraction logic allows unauthenticated attackers to bypass API rate limiting by spoofing client IP headers. This may allow brute-force login attempts or other abuse against Fleet instances...

CVE-2026-46356

Fleet (open-source device management) before v4.80.1 is vulnerable: an IP extraction flaw lets unauthenticated attackers bypass per-IP rate limits by rotating headers like True-Client-IP, X-Real-IP, or X-Forwarded-For, enabling brute-force or credential stuffing on exposed instances. Root cause: ...

CVE-2026-46356 Fleet: IP spoofing allows bypassing API rate limiting

Fleet is open source device management software. Prior to version 4.80.1, a vulnerability in Fleet's IP extraction logic allows unauthenticated attackers to bypass API rate limiting by spoofing client IP headers. This may allow brute-force login attempts or other abuse against Fleet instances...

CVE-2026-43914

A flaw was found in Vaultwarden, a Bitwarden-compatible server. A remote attacker can exploit an unprotected two-factor authentication 2FA function, sendemaillogin, to bypass login brute-force protection. This allows the attacker to repeatedly attempt password guesses without rate-limiting,...
