Prior to 3.39.25, POST /api/global/auth/:tenantId/login incremented the failure counter in packages/worker/src/api/controllers/global/auth.ts only for existing users, while packages/worker/src/middleware/emailLockout.ts returned X-Account-Locked and Retry-After only for locked identifiers. An unauthenticated attacker could compare the response after repeated failures to enumerate valid email addresses and temporarily lock valid accounts. This issue is fixed in version 3.39.25.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
