Title
perfree go-fastdfs-web Apache Shiro RememberMe ShiroConfig.java rememberMeManager hard-coded key
Summary
A security flaw has been discovered in perfree go-fastdfs-web up to 1.3.7. This affects the function rememberMeManager of the file src/main/java/com/perfree/config/ShiroConfig.java of the component Apache Shiro RememberMe. Performing a manipulation results in use of hard-coded cryptographic key
. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitability is reported as difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Title
Use of Hard-Coded Cryptographic Key for Password Storage
Summary
Infor SyteLine ERP uses hard-coded static cryptographic keys to encrypt stored credentials, including user passwords, database connection strings, and API keys. The encryption keys are identical across all installations. An attacker with access to the application binary and database can decrypt all stored credentials.

Title
Unitree UPK files Hard-Coded Key
Summary
Since the encryption algorithm used to protect firmware updates is itself encrypted using key material available to an attacker (or anyone paying attention), the firmware updates may be altered by an unauthorized user, and then trusted by a Unitree product, such as the Unitree Go2 and other models. This issue appears to affect all of Unitree’s current offerings as of February 26, 2026, and so should be considered a vulnerability in both the firmware generation and extraction processes. At the time of this release, there is no publicly-documented mechanism to subvert the update process and insert poisoned firmware packages without the equipment owner’s knowledge.

Title
SiYuan: Information Disclosure and Authentication Bypass via Hardcoded Session Secret
Summary
SiYuan is self-hosted, open source personal knowledge management software. In versions 3.5.1 and prior, the SiYuan Note application utilizes a hardcoded cryptographic secret for its session store. This unsafe practice renders the session encryption ineffective. Since the sensitive AccessAuthCode is stored within the session cookie, an attacker who intercepts or obtains a user's encrypted session cookie (e.g., via session hijacking) can locally decrypt it using the public key. Once decrypted, the attacker can retrieve the AccessAuthCode in plain text and use it to authenticate or take over the session.

Title
Arcade MCP Default Hardcoded Worker Secret Allows Full Unauthorized Access to All HTTP MCP Worker Endpoints
Summary
Arcade MCP allows you to to create, deploy, and share MCP Servers. Prior to 1.5.4, the arcade-mcp HTTP server uses a hardcoded default worker secret ("dev") that is never validated or overridden during normal server startup. As a result, any unauthenticated attacker who knows this default key can forge valid JWTs and fully bypass the FastAPI authentication layer. This grants remote access to all worker endpoints—including tool enumeration and tool invocation—without credentials. This vulnerability is fixed in 1.5.4.

Title
Apache Syncope: Default AES key used for internal password encryption
Summary
Apache Syncope can be configured to store the user password values in the internal database with AES encryption, though this is not the default option.
When AES is configured, the default key value, hard-coded in the source code, is always used. This allows a malicious attacker, once obtained access to the internal database content, to reconstruct the original cleartext password values.
This is not affecting encrypted plain attributes, whose values are also stored using AES encryption.
Users are recommended to upgrade to version 3.0.15 / 4.0.3, which fix this issue.
