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.

Title
Hardcoded Encryption Key Enables Database Credential Access in Milner ImageDirector Capture
Summary
The use of a hard-coded encryption key in calls to the Password function in C2SGlobalSettings.dll in Milner ImageDirector Capture on Windows allows a local attacker to decrypt database credentials by reading the cryptographic key from the executable.
This issue affects ImageDirector Capture: from 7.0.9 before 7.6.3.25808.

Title
BMC Control-M/Agent hardcoded Blowfish keys
Summary
Out-of-support Control-M/Agent versions 9.0.18 to 9.0.20 (and potentially earlier unsupported versions) that are configured to use the non-default Blowfish cryptography algorithm use a hardcoded key. An attacker with access to network traffic and to this key could decrypt network traffic between the Control-M/Agent and Server.
