Lifecycle Timeline
2DescriptionCVE.org
Frappe is a full-stack web application framework. Prior to 16.16.0 and 15.106.0, user enumeration could be performed via the reset_password endpoint. This issue is fixed in versions 16.16.0 and 15.106.0.
AnalysisAI
User enumeration via the reset_password endpoint in Frappe framework exposes valid account usernames to unauthenticated remote attackers across all versions prior to 15.106.0 and 16.16.0. The flaw stems from observable response discrepancies (CWE-203) that allow systematic probing of registered accounts without any credentials. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The reset_password endpoint must be network-reachable - no authentication, no special configuration, and no non-default feature enablement is required beyond a standard Frappe installation with the built-in password reset feature active (which is default). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N) scores 6.9, reflecting a low-complexity, unauthenticated, network-accessible flaw with limited confidentiality impact confined to account existence disclosure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends repeated POST requests to the Frappe reset_password endpoint using a wordlist of email addresses or usernames, and differentiates valid from invalid accounts by observing response body, status code, or timing discrepancies. The resulting list of confirmed valid accounts is fed into credential stuffing tools or used to craft targeted phishing lures against identified users. … |
| Remediation | Upgrade Frappe to version 16.16.0 (v16 branch) or 15.106.0 (v15 branch), which resolve the user enumeration discrepancy in the reset_password endpoint. … Detailed patch versions, workarounds, and compensating controls in full report. |
