what has happened
INCIBE-CERT maintains a public file for the CVE-2026-7787 vulnerability. The source description indicates that it affects IBM Langflow OSS versions 1.0.0 through 1.9.1 and could allow sensitive information to be read or modified using insecure direct object references.
Why it matters
Many companies are rapidly deploying AI tools, automation, and internal flows. If these systems are exposed, poorly segregated or without version control, an authorization vulnerability can turn into a data leak, flow alteration or improper access to operational information.
What to check now
Checks for Langflow in internal environments, labs, or test servers; identifies installed version; limits external exposure; check authentication and permissions; logs accesses; and apply manufacturer update or mitigation when available.
Relationship with ISO 27001
This case fits with asset management, change control, access control, vulnerability management and evidence logging. It is not enough to know that the tool exists: there must be a responsible person, a known version and patching criteria.
Checklist for companies
- Inventory of AI and automation tools.
- Version control and patches.
- Access restriction by VPN, network or identity.
- Review of permissions and accessible objects.
- Evidence of decision: patched, mitigated or removed.
