Threats tagged 'ghsa-hprh-85vv-3jpq'

SurrealDB versions from 3.1.0 up to but not including 3.3.0 have an improper authentication vulnerability. The MCP BoundSubject fingerprint incorrectly uses the access method name rather than a per-user identity for JWT/Bearer tokens. This flaw allows attackers possessing a valid low-privilege token for the same access method and a victim's mcp-session-id to hijack the victim's session and execute MCP tools with the victim's roles and permissions.
