IBM Langflow OSS 1.0.0 through 1.11.2 could allow a remote authenticated attacker to obtain sensitive information due to improper validation of symbolic links.
AnalysisAI
Sensitive file disclosure in IBM Langflow OSS 1.0.0 through 1.11.2 allows authenticated remote attackers to read arbitrary files on the server by exploiting improper validation of symbolic links. The flaw, classified under CWE-22 (Path Traversal), enables an attacker with valid credentials to escape intended directory boundaries by manipulating symlink resolution, potentially exposing configuration files, credentials, or other sensitive server-side content. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session in IBM Langflow OSS (PR:L per CVSS vector) - unauthenticated access is not sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.5 (Medium) reflects a genuinely constrained risk profile: the attack requires valid authentication (PR:L), which eliminates unauthenticated mass exploitation. … 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 | Apply the vendor-released patch as directed by IBM's advisory at https://www.ibm.com/support/pages/node/7285641. … Detailed patch versions, workarounds, and compensating controls in full report. |
