CVE-2026-8056
Authenticated users can override Langflow component parameters via API, enabling code injection risk.
Is CVE-2026-8056 being exploited?
Not confirmed. CVE-2026-8056 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 0.53% probability of exploitation in the next 30 days.
How severe is CVE-2026-8056?
CVE-2026-8056 is rated High. 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-2026-8056?
Yes. A fix has been recorded for CVE-2026-8056. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-8056 affect?
CVE-2026-8056 affects IBM Langflow OSS 1.0.0 through 1.10.0, Langflow API (apply_tweaks function). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-8056?
Restrict access, apply firewall/API auth, monitor logs, and update to patched release when available.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Authenticated attackers can override runtime parameters via the API (CWE-94), enabling code injection, model manipulation, or possible RCE.
Patch when possible
- affected>= 1.0.0 and <= 1.10.0
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.
