Technical description

Kasa EC71 v4 and EC70 v4 firmware contains a static cryptographic private key stored in a read-only filesystem that is shared across devices. An attacker with access to the firmware image can extract the embedded key. Successful exploitation may allow an unauthenticated attacker on the same network to use this key in the web management service, compromising the confidentiality of encrypted communications. This may enable passive decryption of traffic or active man-in-the-middle (MITM) attacks

——17An issue was discovered in Siklu Communications Etherhaul 8010TX and 1200FX devices, Firmware 7.4.0 through 10.7.3 and possibly other previous versions. The rfpiped service listening on TCP port 555 which uses static AES encryption keys hardcoded in the binary. These keys are identical across all devices, allowing attackers to craft encrypted packets that execute arbitrary commands without authentication. This is a failed patch for CVE-2017-7318. This issue may affect other Etherhaul series devices with shared firmware.12d CVE-2026-562719.8 CRI

——9Flowise before 3.1.0 (affected versions 3.0.13 and earlier) uses weak hardcoded default JWT secrets ('auth_token', 'refresh_token') and default audience and issuer values ('AUDIENCE', 'ISSUER') in the enterprise passport authentication middleware (packages/server/src/enterprise/middleware/passport/index.ts). When the corresponding environment variables (JWT_AUTH_TOKEN_SECRET, JWT_REFRESH_TOKEN_SECRET, JWT_AUDIENCE, JWT_ISSUER) are not set, the application silently falls back to these publicly known defaults, allowing an attacker to forge valid JWTs and impersonate any user, including administrators, resulting in authentication bypass.3d CVE-2026-57172—

——6DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, ShareSecretManage uses a hardcoded default share link signature key, allowing an attacker who can obtain a passwordless share for a resource and user to use the known key link-pwd-fit2cloud to forge linkToken JWTs, bypass TokenFilter verification, and access backend resources as the share creator even if the original share has been revoked. This issue is fixed in version 2.10.24.9d CVE-2026-500919.1 CRI

———clawvet self-hosted API server (apps/api) before 0.7.5 hard-codes a fallback JWT secret ('clawvet-dev-secret-change-me') in auth.ts and ships it as the default in .env.example. Because GET /api/v1/scans returns scan records containing userId values without authentication, a remote unauthenticated attacker can harvest a victim's userId, forge a valid HS256 cg_session cookie offline using the known secret, and call GET /api/v1/auth/me to obtain the victim's email address, subscription plan, and secret apiKey. The published clawvet npm package (CLI only) is not affected.11h
