IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to read arbitrary files due to improper access control.
AnalysisAI
Arbitrary file read in IBM Langflow OSS 1.0.0 through 1.11.5 allows a remote authenticated attacker to access files outside their authorized scope due to improper access control (CWE-284). The CVSS vector confirms PR:L, meaning exploitation requires valid credentials but no elevated privileges, making this a post-authentication authorization flaw rather than an authentication bypass. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session with at least low-privilege access to IBM Langflow OSS (confirmed by PR:L in CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) reflects a medium-severity finding with high confidentiality impact but zero integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade IBM Langflow OSS to a version beyond 1.11.5 per IBM's patch at https://www.ibm.com/support/pages/node/7286657. … Detailed patch versions, workarounds, and compensating controls in full report. |
