Mar 3, 2026A vulnerability was determined in Tuya App and SDK 24.07.11 on Android.CVE-2026-3465 · Other software · Tuya · reported by VulDBLow 1.3
A vulnerability was determined in Tuya App and SDK 24.07.11 on Android. Affected by this vulnerability is an unknown functionality of the component JSON Data Point Handler. This manipulation of the argument cruise_time causes denial of service. Remote exploitation of the attack is possible. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been publicly disclosed and may be utilized. There is ongoing doubt regarding the real existence of this vulnerability. The vendor disagrees with the conclusion of the finding: "The described vulnerability fails to prove its feasibility or exploitability by attackers. The issue essentially does not constitute a security vulnerability, aligning more closely with abnormal product functionality." These considerations are properly reflected within the CVSS vector.

Nov 24, 2025Cross-Site Request Forgery (CSRF) vulnerability in the OAuth implementation of the Tuya SDK 6.5.0 for Android and iOS, affects the Tuya Smart and Smartlife mobiCVE-2025-56400 · Other software · Tuya · reported by MITREHigh 8.8
Cross-Site Request Forgery (CSRF) vulnerability in the OAuth implementation of the Tuya SDK 6.5.0 for Android and iOS, affects the Tuya Smart and Smartlife mobile applications, as well as other third-party applications that integrate the SDK, allows an attacker to link their own Amazon Alexa account to a victim's Tuya account. The applications fail to validate the OAuth state parameter during the account linking flow, enabling a cross-site request forgery (CSRF)-like attack. By tricking the victim into clicking a crafted authorization link, an attacker can complete the OAuth flow on the victim's behalf, resulting in unauthorized Alexa access to the victim's Tuya-connected devices. This affects users regardless of prior Alexa linkage and does not require the Tuya application to be active at the time. Successful exploitation may allow remote control of devices such as cameras, doorbells, door locks, or alarms.

Jun 6, 2025WOLFBOX Level 2 EV Charger tuya_svc_devos_activate_result_parse Heap-based Buffer Overflow Remote Code Execution Vulnerability.CVE-2025-5750 · Other software · WOLFBOX · reported by zdi-disclosures@trendmicro.comHigh 8.8
WOLFBOX Level 2 EV Charger tuya_svc_devos_activate_result_parse Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of WOLFBOX Level 2 EV Charger. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the secKey, localKey, stdTimeZone and devId parameters. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26294.

KERUI HD 3MP 1080P Tuya Camera 1.0.4 has a command injection vulnerability in the module that connects to the local network via a QR code. This vulnerability allows an attacker to create a custom, unauthenticated QR code and abuse one of the parameters, either SSID or PASSWORD, in the JSON data contained within the QR code. By that, the attacker can execute arbitrary code on the camera.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories.
