| CVE-2025-53540 | 1 Espressif | 1 Arduino-esp32 | 2025-07-08 | N/A |
| arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Several OTA update examples and the HTTPUpdateServer implementation are vulnerable to Cross-Site Request Forgery (CSRF). The update endpoints accept POST requests for firmware uploads without CSRF protection. This allows an attacker to upload and execute arbitrary firmware, resulting in remote code execution (RCE). This vulnerability is fixed in 3.2.1. | ||||
| CVE-2025-52471 | 1 Espressif | 1 Esp-idf | 2025-07-06 | N/A |
| ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. An integer underflow vulnerability has been identified in the ESP-NOW protocol implementation within the ESP Wi-Fi component of versions 5.4.1, 5.3.3, 5.2.5, and 5.1.6 of the ESP-IDF framework. This issue stems from insufficient validation of user-supplied data length in the packet receive function. Under certain conditions, this may lead to out-of-bounds memory access and may allow arbitrary memory write operations. On systems without a memory protection scheme, this behavior could potentially be used to achieve remote code execution (RCE) on the target device. In versions 5.4.2, 5.3.4, 5.2.6, and 5.1.6, ESP-NOW has added more comprehensive validation logic on user-supplied data length during packet reception to prevent integer underflow caused by negative value calculations. For ESP-IDF v5.3 and earlier, a workaround can be applied by validating that the `data_len` parameter received in the RX callback (registered via `esp_now_register_recv_cb()`) is a positive value before further processing. For ESP-IDF v5.4 and later, no application-level workaround is available. Users are advised to upgrade to a patched version of ESP-IDF to take advantage of the built-in mitigation. | ||||
| CVE-2025-27840 | 1 Espressif | 2 Esp32, Esp32 Firmware | 2025-05-12 | 6.8 Medium |
| Espressif ESP32 chips allow 29 hidden HCI commands, such as 0xFC02 (Write memory). | ||||
| CVE-2022-24893 | 1 Espressif | 1 Esp-idf | 2025-04-23 | 7.5 High |
| ESP-IDF is the official development framework for Espressif SoCs. In Espressif’s Bluetooth Mesh SDK (`ESP-BLE-MESH`), a memory corruption vulnerability can be triggered during provisioning, because there is no check for the `SegN` field of the Transaction Start PDU. This can result in memory corruption related attacks and potentially attacker gaining control of the entire system. Patch commits are available on the 4.1, 4.2, 4.3 and 4.4 branches and users are recommended to upgrade. The upgrade is applicable for all applications and users of `ESP-BLE-MESH` component from `ESP-IDF`. As it is implemented in the Bluetooth Mesh stack, there is no workaround for the user to fix the application layer without upgrading the underlying firmware. | ||||
| CVE-2024-53406 | 1 Espressif | 1 Esp-idf | 2025-04-03 | 8.8 High |
| Espressif Esp idf v5.3.0 is vulnerable to Insecure Permissions resulting in Authentication bypass. In the reconnection phase, the device reuses the session key from a previous connection session, creating an opportunity for attackers to execute security bypass attacks. | ||||
| CVE-2024-33454 | 1 Espressif | 1 Esp-idf | 2025-02-13 | 6.5 Medium |
| Buffer Overflow vulnerability in esp-idf v.5.1 allows a remote attacker to execute arbitrary code via a crafted script to the Bluetooth stack component. | ||||
| CVE-2024-53845 | 1 Espressif | 1 Esp-idf | 2024-12-12 | N/A |
| ESPTouch is a connection protocol for internet of things devices. In the ESPTouchV2 protocol, while there is an option to use a custom AES key, there is no option to set the IV (Initialization Vector) prior to versions 5.3.2, 5.2.4, 5.1.6, and 5.0.8. The IV is set to zero and remains constant throughout the product's lifetime. In AES/CBC mode, if the IV is not properly initialized, the encrypted output becomes deterministic, leading to potential data leakage. To address the aforementioned issues, the application generates a random IV when activating the AES key starting in versions 5.3.2, 5.2.4, 5.1.6, and 5.0.8. This IV is then transmitted along with the provision data to the provision device. The provision device has also been equipped with a parser for the AES IV. The upgrade is applicable for all applications and users of ESPTouch v2 component from ESP-IDF. As it is implemented in the ESP Wi-Fi stack, there is no workaround for the user to fix the application layer without upgrading the underlying firmware. | ||||
| CVE-2024-28183 | 1 Espressif | 1 Esp-idf | 2024-11-21 | 6.1 Medium |
| ESP-IDF is the development framework for Espressif SoCs supported on Windows, Linux and macOS. A Time-of-Check to Time-of-Use (TOCTOU) vulnerability was discovered in the implementation of the ESP-IDF bootloader which could allow an attacker with physical access to flash of the device to bypass anti-rollback protection. Anti-rollback prevents rollback to application with security version lower than one programmed in eFuse of chip. This attack can allow to boot past (passive) application partition having lower security version of the same device even in the presence of the flash encryption scheme. The attack requires carefully modifying the flash contents after the anti-rollback checks have been performed by the bootloader (before loading the application). The vulnerability is fixed in 4.4.7 and 5.2.1. | ||||
| CVE-2023-46894 | 1 Espressif | 1 Esptool | 2024-11-21 | 7.5 High |
| An issue discovered in esptool 4.6.2 allows attackers to view sensitive information via weak cryptographic algorithm. | ||||
| CVE-2023-35818 | 1 Espressif | 44 Esp-eye, Esp-eye Firmware, Esp32-d0wd-v3 and 41 more | 2024-11-21 | 6.8 Medium |
| An issue was discovered on Espressif ESP32 3.0 (ESP32_rev300 ROM) devices. An EMFI attack on ECO3 provides the attacker with a capability to influence the PC value at the CPU context level, regardless of Secure Boot and Flash Encryption status. By using this capability, the attacker can exploit another behavior in the chip to gain unauthorized access to the ROM download mode. Access to ROM download mode may be further exploited to read the encrypted flash content in cleartext format or execute stub code. | ||||
| CVE-2021-41104 | 2 Esphome, Espressif | 3 Esphome Firmware, Esp32, Esp8266 | 2024-11-21 | 7.5 High |
| ESPHome is a system to control the ESP8266/ESP32. Anyone with web_server enabled and HTTP basic auth configured on version 2021.9.1 or older is vulnerable to an issue in which `web_server` allows over-the-air (OTA) updates without checking user defined basic auth username & password. This issue is patched in version 2021.9.2. As a workaround, one may disable or remove `web_server`. | ||||
| CVE-2021-34173 | 1 Espressif | 2 Esp32, Esp32 Firmware | 2024-11-21 | 7.5 High |

An attacker can send a crafted BluFi protocol Write Attribute command to characteristic 0xFF01. With manipulated packet fields, there is a buffer overflow. | ||||
| CVE-2020-13595 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 6.5 Medium |
| The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion on the host stack when receiving a packet with an MIC failure. An attacker within radio range can silently trigger the assertion (which disables the target's BLE stack) by sending a crafted sequence of BLE packets. | ||||
| CVE-2020-13594 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 6.5 Medium |
| The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.2 and earlier (for ESP32 devices) does not properly restrict the channel map field of the connection request packet on reception, allowing attackers in radio range to cause a denial of service (crash) via a crafted packet. | ||||
| CVE-2020-12638 | 1 Espressif | 3 Esp-idf, Esp8266 Nonos Sdk, Esp8266 Rtos Sdk | 2024-11-21 | 6.8 Medium |
| An encryption-bypass issue was discovered on Espressif ESP-IDF devices through 4.2, ESP8266_NONOS_SDK devices through 3.0.3, and ESP8266_RTOS_SDK devices through 3.3.
