Versions of SiYuan prior to v3.8.2 are susceptible to an unbounded session creation vulnerability in the Basic Auth handler of the publish-service, allowing authenticated attackers to exhaust server memory. This can lead to indefinite memory growth and result in a denial of service, impacting system availability. Organizations using affected versions should prioritize patching to mitigate this risk.

Original NVD Description

SiYuan versions before v3.8.2 contain an unbounded session creation vulnerability in the publish-service Basic Auth handler that allows authenticated attackers to exhaust memory. Attackers can repeatedly authenticate with valid credentials to create persistent session entries without expiry or capacity limits, causing indefinite process memory growth and denial of service.
