CVE-2026-56278

CRITICAL9.1

Published 2026-06-30 · Updated 2026-07-01 · Source disclosure@vulncheck.com

Description

Flowise before 3.1.0 (affected versions 3.0.13 and earlier) uses a weak hardcoded default secret ('flowise') for the express-session middleware when the EXPRESS_SESSION_SECRET environment variable is not set (packages/server/src/enterprise/middleware/passport/index.ts). Because this default secret is publicly visible in the source code, an attacker can forge valid signed session cookies to impersonate any user and bypass authentication.

CVE-2026-58457
Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02) contains an unauthenticated OS command injection vulnerability that allows network-adjacent attackers to execute arbitrary shell commands by injecting unsanitized input through the smacfilter_conf handler in the commuos web backend. Attackers can append semicolon-delimited payloads to the name, enable, or mac GET parameters, which are passed without sanitization into sprintf() to build uci shell commands executed via doSystemCmdComlib(), granting full root-level control of the device.

CVE-2026-50160
Hoppscotch is an API development ecosystem. In self-hosted deployments of hoppscotch-backend from version 2026.4.1 and earlier, the unauthenticated POST /v1/onboarding/config endpoint is vulnerable to mass assignment. The global NestJS ValidationPipe is configured without whitelist: true, so extra properties on the request body that are not declared in SaveOnboardingConfigRequest are not stripped and are iterated in the service layer as if they were legitimate InfraConfig entries. Because keys such as JWT_SECRET and SESSION_SECRET are valid InfraConfigEnum values and are not explicitly rejected during validation, an unauthenticated attacker who can reach a fresh instance before onboarding completes (or when no users exist) can overwrite these values in the database. Overwriting JWT_SECRET gives the attacker control of the JWT signing key, allowing them to forge tokens for any user, including administrators, and results in full server compromise. The issue is fixed in hoppscotch 2026.5.0.

CVE-2026-58453
JAIOTlink C492A-W6 Wi-Fi IP cameras running firmware 4.8.30.57701411 contain a hard-coded credentials vulnerability that allows network-adjacent attackers to gain unauthorized access by using the default admin username with an empty password accepted by the anyka_ipc HTTP service on port 80. Attackers can authenticate with these hardcoded credentials to access camera snapshots, video streams, network configuration, and factory-level API endpoints including the SetMAC command injection surface.

CVE-2026-34117
Guardian language-system passes the id GET parameter directly into a PHP exec() call in text_to_subtitles.php (line 19) without sanitization: exec(\"php jobs/text_to_subtitles.php \".$login_session.\" \".$_GET['id'].\" ...\"). No authentication is required. An unauthenticated remote attacker can append shell metacharacters to execute arbitrary OS commands on the server.
