Who should care

Defenders responsible for Langflow OSS deployments, particularly those using versions 1.0.0 through 1.12.2, should assess potential exposure and prioritize verification and remediation efforts.

Why it matters

CVE-2026-97676 is a high-severity vulnerability in Langflow OSS that allows remote authenticated attackers to execute arbitrary code, potentially leading to sandbox escapes and code execution risks. Defenders should prioritize verifying exposure, assessing potential risks, and remediating affected versions.

• Potential code execution risks in Langflow OSS deployments
• Sandbox escape vulnerability allowing arbitrary code execution
• Need for verification and remediation of affected versions

Technical summary

CVE-2026-97676 is a high-severity vulnerability in Langflow OSS, allowing remote authenticated attackers to execute arbitrary code due to improper neutralization of special elements used in code. This results in a sandbox escape. The vulnerability affects Langflow OSS versions 1.0.0 through 1.12.2, with a CVSS score of 8.8. Defenders should prioritize verifying exposure and assessing potential code execution risks in Langflow OSS deployments.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential code execution risks in Langflow OSS deployments, particularly for versions 1.0.0 through 1.12.2.

Recommended defensive actions

• Verify Langflow OSS version and assess exposure
• Review and update Langflow OSS to a version outside the affected range if possible
• Monitor for potential code execution attempts in Langflow OSS deployments

Evidence notes

The CVE record and source item provide details on the vulnerability, including its CVSS score of 8.8 and affected versions of Langflow OSS. The official CVE Program record (cve-org) and the NIST NVD detail page (nvd) offer source-provided CVE metadata and vulnerability assessments. However, the exact scope of affected deployments and specific code execution risks remain to be verified by defenders. Verification tasks should focus on confirming whether Langflow OSS versions 1.0.0 to 1.
