SiYuan versions prior to 3.7.4 expose sensitive debug endpoints, such as heap and goroutine dumps, without authentication when not operating in production mode. This vulnerability allows attackers to access in-memory secrets, including AccessAuthCode and AI provider API keys, posing a significant risk to the confidentiality of sensitive information. Organizations using SiYuan should prioritize patching to mitigate the risk of unauthorized data exposure.
