CVE-2026-74799: Insertion of Sensitive Information Into Debugging Code in siyuan-note siyuan
SiYuan before 3.7.4 registers Go net/http/pprof debug endpoints including heap and goroutine dumps without authentication when --mode flag is not set to exactly prod. Attackers can access /debug/pprof/heap and related endpoints to extract in-memory secrets including AccessAuthCode and AI provider API keys.
AI Analysis
Technical Summary
SiYuan note-taking software prior to version 3.7.4 registers Go net/http/pprof debugging endpoints such as heap and goroutine dumps without requiring authentication if the --mode flag is not set exactly to 'prod'. This misconfiguration enables unauthorized access to debug endpoints that can leak sensitive runtime memory data, including authentication codes and API keys. No official patch or remediation level has been confirmed in the provided data.
Potential Impact
An attacker can remotely access debug endpoints to extract sensitive in-memory secrets like AccessAuthCode and AI provider API keys, potentially leading to unauthorized access or misuse of these credentials. The vulnerability is remotely exploitable without privileges or user interaction, resulting in high confidentiality impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, ensure the --mode flag is set exactly to 'prod' in production environments to disable unauthenticated debug endpoints.
