CVE-2026-9196
Authenticated code execution in Langflow via model-generated Python during validation.
Is CVE-2026-9196 being exploited?
Not confirmed. CVE-2026-9196 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.30% probability of exploitation in the next 30 days.
How severe is CVE-2026-9196?
CVE-2026-9196 is rated High with a CVSS score of 8.1. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-9196?
Yes. A fix has been recorded for CVE-2026-9196. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-9196 affect?
CVE-2026-9196 affects IBM Langflow OSS 1.0.0 - 1.10.3. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-9196?
Restrict access, sandbox backend, block outbound traffic, and update to fixed release when published.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Authenticated attacker can force backend to run model-generated Python pre-approval, enabling outbound network, file access, or data exfiltration as the backend user.
Immediate action required
- affected>= 1.0.0 and <= 1.10.3
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
