Lifecycle Timeline
9DescriptionCVE.org
A weakness has been identified in langflow-ai langflow up to 1.8.3. Impacted is the function remove_api_keys/has_api_terms of the file src/backend/base/langflow/api/utils/core.py of the component Flow Using API. This manipulation causes unprotected storage of credentials. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Langflow up to version 1.8.3 stores API credentials without encryption in the remove_api_keys and has_api_terms functions, allowing remote attackers with high privileges to disclose sensitive credentials through the Flow Using API component. The vulnerability has publicly available exploit code, though real-world exploitation likelihood is constrained by the requirement for high-privilege access; vendor has not responded to disclosure.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to possess a high-privilege credential (admin or API key with administrative role) on the Langflow instance. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 2.7 (Low severity) reflects the constraint of PR:H (high privilege requirement), which significantly limits real-world exploitability despite AV:N (network accessible). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An insider or attacker who has gained a high-privilege admin token or API key to a Langflow instance can call the remove_api_keys or has_api_terms functions via the Flow Using API to retrieve plaintext copies of stored third-party API credentials (e.g., OpenAI keys, database passwords). These credentials are then used to pivot to dependent services. … |
| Remediation | Primary remediation is to upgrade Langflow beyond version 1.8.3 once a patched release is available; however, no confirmed fix version has been announced by langflow-ai as of this analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
