Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Dependency confusion needs the attacker to pre-position a name-matching package and win resolution precedence, so AC:H; it is remote and needs no victim auth (AV:N/PR:N), with total host impact.

IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote attacker to execute arbitrary code due to an expected dependency confusion.
AnalysisAI
Remote code execution can result in IBM Langflow OSS 1.0.0 through 1.12.2 through a dependency confusion weakness, where the product resolves an expected dependency from a public package registry instead of the intended trusted source. The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates an unauthenticated remote attacker with no user interaction required, and the unpatched severity is rated 9.8; however, our independent assessment lowers the attack complexity to AC:H because successful exploitation depends on the attacker knowing or guessing the exact dependency name and on the victim's resolver preferring an attacker-published public package over the legitimate one, typically during an install, build, or import event rather than against a running service. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the targeted environment's dependency resolution (package manager / build or install pipeline for Langflow OSS 1.0.0-1.12.2) to fetch a dependency from a public registry where the attacker has pre-published a malicious package matching the expected dependency name, causing attacker code to run during install/import. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict sharply and should temper the headline 9.8. … 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 fix referenced from IBM's advisory at https://www.ibm.com/support/pages/node/7290694; patch availability is confirmed per vendor advisory, but no exact fixed version number is disclosed in the available data, so confirm the specific remediated release with IBM before upgrading, and move off any 1.0.0-1.12.2 build. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every deployment of IBM Langflow OSS and identify systems running versions 1.0.0 through 1.12.2, and immediately restrict outbound access from build, CI/CD, and install environments to public package registries (PyPI and similar) so that dependency resolution cannot reach attacker-controlled packages; if a legitimate build requires public resolution, pin and hash-verify every dependency. …
