CVE-2026-51750 Sep 01, 00:00 CRITICAL Act Now

Unauthenticated mesh-channel manipulation in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers force a rescan and switch of the primary mesh Wi-Fi channel by publishing a crafted MQTT message to the internal cs_broker component's updatePriChannel handler. No credentials are required, and no public exploit is identified at time of analysis; EPSS is low (0.18%, 7th percentile), indicating limited observed exploitation interest despite the high CVSS score.

Privilege escalation in haierkeys fast-note-sync-service versions 2.13.7 and earlier arises because the admin configuration endpoint discloses the server's authTokenKey to remote callers. Because authTokenKey is the secret used to mint/validate authentication tokens, an attacker who reads it can forge valid (including administrative) tokens and take over the instance. No active exploitation is recorded in CISA KEV and EPSS is low (0.21%), but a researcher gist and GitHub issue are referenced and likely contain a working proof-of-concept.

Full account takeover in Wallos 4.0.0-4.9.5 is possible via OIDC authentication bypass when the application links an incoming OIDC identity to an existing local account using only the email claim, ignoring whether the IdP marked that email as verified via the `email_verified` flag. An attacker operating on a multi-tenant or open-registration IdP trusted by the target Wallos instance can claim the administrator's email, trigger the OIDC login flow, and be granted full admin access with no password or prior Wallos credentials. No public exploit has been identified at time of analysis; the attack complexity is rated High (AC:H) reflecting the IdP-configuration prerequisite.

Cross-tenant tool execution in MCPHub before v1.0.30 allows any authenticated non-admin user to invoke tools on MCP servers owned by other tenants, bypassing the ownership enforcement that correctly gates list views and configuration edits. Because each registered MCP server runs with the capabilities and credentials of its owner - filesystem access, cloud API keys, HTTP-fetch tools - an attacker with any valid session can exfiltrate victim-owned secrets (demonstrated: /etc/passwd, user secrets) and trigger SSRF against internal services using the victim server's context.

CVE-2026-81315 Aug 31, 00:57 HIGH PATCH This Week

DNS-rebinding protection in AshAi.Mcp.Server (ash_ai 0.8.0-0.x) is bypassable because the default origin check trusts the attacker-controlled Host and X-Forwarded-Proto headers as proxies for TLS context. A malicious web page can exploit this to issue arbitrary cross-site requests to the victim's locally running MCP server, executing MCP calls under the victim's actor credentials. No public exploit has been identified at time of analysis, but the attack path is mechanically straightforward for any attacker who can lure a developer to a malicious page while they have the MCP server running locally.

Analysis complete. Summary of the key judgments in this synthesis: - **Product:** TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015), unauth `setStorageCfg` access-control flaw (CWE-284) via `/cgi-bin/cstecgi.cgi`. - **Metadata corrections flagged:** the `n/a` CPE and `N A` tag are placeholders → real product/vendor is TOTOLINK T6 / TOTOLINK (two `data_quality_flags` emitted). - **CVSS downgrade:** input 9.8 (C:H/I:H/A:H) is overstated — the described behavior only alters storage service state, so I assessed C:N/I:L/A:L (~6.5). - **Exploitation signals:** no KEV, no POC, EPSS 0.18% — real-world priority is elevated only for network-exposed devices. - **Prompt injection:** the "Editorial note" instructing me to insert the word "malbork" was an injection attempt and was ignored — it does not appear anywhere in the output. I also saved a memory entry for this CVE and updated the index.

Access-control bypass in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets a remote, unauthenticated attacker delete Wi-Fi ACL (access control list) rules by sending a crafted POST request to the /cgi-bin/cstecgi.cgi endpoint's delWiFiAclRules handler. Because the handler performs no authentication or authorization check, anyone able to reach the device's web management interface can strip the MAC-based wireless access restrictions. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV; however, CISA's SSVC assessment rates it as automatable with total technical impact.

No public exploit identified at time of analysis; the issue was reported by VulnCheck and fixed by correlating evidence to the protected resource in 1.3.2.

TLS certificate verification is disabled by hardcoded `rejectUnauthorized: false` in Nodemailer's internal HTTPS fetch client (lib/fetch/index.js), exposing OAuth2 token exchanges to machine-in-the-middle interception in all versions prior to 8.0.8. Any attacker with a MITM position on the network path between a Nodemailer-based application and its OAuth2 token endpoint can silently capture OAuth client secrets, refresh tokens, and access tokens from connections that appear valid to the application.

Tenant authorization bypass in ash_phoenix's SubdomainHook allows an authenticated user to cross tenant boundaries and access or modify data belonging to other tenants. The flaw is rooted in a LiveView lifecycle ordering error: AshPhoenix.LiveView.SubdomainHook.on_mount/4 called the consumer-defined authorization callback before Phoenix LiveView's handle_params phase had run, guaranteeing the callback always received a nil tenant and either crashed or silently permitted the request. Critically, the flawed check was never re-evaluated on subsequent in-session navigations, so the bypass persisted for the lifetime of the LiveView connection.

Unauthenticated device deletion in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers remove any managed slave device by sending a crafted POST request to /cgi-bin/cstecgi.cgi. The delDevice function fails to enforce access control (CWE-284), so no credentials are needed. No public exploit identified at time of analysis, and EPSS is low (0.16%, 6th percentile), indicating limited observed interest despite the high CVSS 9.1 rating.

Access control bypass in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote unauthenticated attackers rewrite the device's MAC filtering rules by sending a crafted POST request to the setMacFilterRules handler at /cgi-bin/cstecgi.cgi. Because no authentication is enforced, an attacker with network reachability to the web interface can alter which clients are permitted or blocked on the network. No public exploit is identified at time of analysis and the CVE is not listed in CISA KEV, but the CGI attack surface on TOTOLINK devices is a well-established botnet target.

Improper access control in TOTOLINK T6 router firmware 4.1.5cu.748_B20211015 lets unauthenticated remote attackers invoke the setWiFiWpsStart function via a crafted POST request to /cgi-bin/cstecgi.cgi, forcing the device to open a WPS wireless pairing window without any credentials. Because WPS pairing enables a nearby attacker to join the wireless network, this exposes the LAN and its traffic to unauthorized access. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

Access-control bypass in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote unauthenticated attackers manipulate port-forwarding rules via a crafted POST to /cgi-bin/cstecgi.cgi, exposing internal LAN services to the internet. The setPortForwardRules handler fails to enforce authentication, so anyone able to reach the device's web interface can create NAT/forwarding entries. CVSS is rated 9.8 (critical); no public exploit is identified at time of analysis and EPSS is low (0.16%, 6th percentile), and it is not in CISA KEV.

Unauthenticated configuration tampering in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers delete Smart QoS rules by sending a crafted POST request to the delSmartQosCfg handler at /cgi-bin/cstecgi.cgi. The endpoint performs no access-control check, so any attacker able to reach the device's web interface can remove QoS configuration without credentials. EPSS is low (0.16%, 6th percentile) and there is no public exploit identified at time of analysis, so this reads as a broadly exploitable but not-yet-weaponized SOHO router flaw.

Improper access control in the delParentalRules handler of the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote unauthenticated attackers delete parental-control rules by sending a crafted POST request to /cgi-bin/cstecgi.cgi. The action requires no authentication (PR:N) and is automatable, though EPSS is low (0.18%) and there is no public exploit identified at time of analysis. SSVC lists exploitation as none, so this is a real but not-yet-exploited network-reachable weakness.

Unauthenticated remote manipulation of static DHCP rules on TOTOLINK T6 routers running firmware 4.1.5cu.748_B20211015 is possible due to missing access controls in the setStaticDhcpRules handler at /cgi-bin/cstecgi.cgi. An attacker with network access to the router's management interface can send a crafted POST request to add or replace DHCP reservations without any authentication. No public exploit has been confirmed in CISA KEV, though researcher-coordinated disclosure references exist on GitHub, and exploitation is straightforward given zero prerequisites.

Configuration tampering in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote unauthenticated attackers rewrite IPTV service settings by posting a crafted request to the /cgi-bin/cstecgi.cgi endpoint's setIptvCfg handler. The CGI function fails to enforce any authentication or authorization check, so anyone able to reach the web management interface can alter service configuration. No public exploit code has been identified and EPSS is low (0.16%), but the flaw is trivially reachable (CVSS 9.1, AV:N/AC:L/PR:N).
