CVE-2026-119736 Overview
Attendo (formerly Petpooja Payroll) Admin Android application version 3.0.13 and earlier contains a hard-coded credentials vulnerability that allows attackers to extract production MQTT broker credentials by decompiling the APK's bundled Flutter configuration assets such as production.json and device-command configuration files. Attackers can use the recovered credentials to authenticate to the production MQTT broker over TCP 1883, access messaging topics containing employee attendance records, personal identifiers, Base64-encoded photographs, device telemetry, and authentication material, and publish messages to those topics, resulting in exposure of sensitive data and potential unauthorized message injection.

Frequently asked questions
Related CVEs
A hard-coded cryptographic key is used by Altium Enterprise Server to sign file download URLs in the Vault service. Because the key is identical across all installations, an unauthenticated network attacker who can reach the server can forge valid download signatures and retrieve files from the Vault storage area without any authentication, session, or credentials. A separate path traversal vulnerability in the same download endpoint allows the configured storage root to be escaped, enabling reads of arbitrary files on the server filesystem. Combined, these issues allow an unauthenticated attacker to obtain sensitive server configuration and key material, which can lead to full server compromise. The vulnerability can be chained with CVE-2026-9152 to enumerate and bulk-download stored content. Altium 365 cloud deployments are not impacted in practice, as file storage uses object storage rather than the local filesystem.
Two undocumented privileged accounts exist in Autel Maxi Charger Single firmware through V1.03.51. The accounts use vendor-defined password derivation mechanisms based on device-specific values, allowing an attacker with knowledge of the algorithm and required inputs to authenticate to the web management interface with administrative privileges.
Dell RecoverPoint for Virtual Machines, versions prior to 6.0.3.1 HF1, contain a hardcoded credential vulnerability. This is considered critical as an unauthenticated remote attacker with knowledge of the hardcoded credential could potentially exploit this vulnerability leading to unauthorized access to the underlying operating system and root-level persistence. Dell recommends that customers upgrade or apply one of the remediations as soon as possible.
The upload.cgi binary, responsible for processing device backups, contains a hardcoded AES encryption key. This allows an attacker to decrypt, modify, and re-encrypt system backups, facilitating persistent backdoor injection.
Autel Maxi Charger Single firmware through V1.03.51 contains a hard-coded authentication token that bypasses authorization checks for multiple management endpoints. An attacker can supply the special token value to invoke privileged functionality without valid authentication.
A vulnerability in the database service feature of Cisco Expressway Series could allow an unauthenticated, remote attacker with network access to a Cisco Expressway device to execute arbitrary operating system commands as root. This vulnerability is due to the use of persistent cookies. Additionally, there is insufficient validation of client certificates when the TLS Verify Mode is set to Enabled for clustering, which means that client certificates are not validated. An attacker with possession of the cookies could exploit this vulnerability by connecting to the database service and invoking specific remote procedure call (RPC) commands. A successful exploit could allow the attacker to execute arbitrary commands as root on the underlying operating system of an affected device. Note: Cisco Expressway Series refers to Cisco Expressway Core (Expressway-C) devices and Cisco Expressway Edge (Expressway-E) devices.
