How severe is GHSA-rvqx-wpfh-mfx7?

No CVSS score has been assigned to GHSA-rvqx-wpfh-mfx7 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-rvqx-wpfh-mfx7?

GHSA-rvqx-wpfh-mfx7 affects the following packages: langflow (PyPI), langflow-base (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-rvqx-wpfh-mfx7?

Update langflow to 1.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rvqx-wpfh-mfx7 is resolved across your whole dependency graph.

How do I detect GHSA-rvqx-wpfh-mfx7 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for langflow, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-rvqx-wpfh-mfx7 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is GHSA-rvqx-wpfh-mfx7 actively exploited in the wild?

Yes. There are 11 known exploit references for GHSA-rvqx-wpfh-mfx7, including 2 documented proof-of-concept exploits on Exploit-DB. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-rvqx-wpfh-mfx7?

GHSA-rvqx-wpfh-mfx7 has an EPSS (Exploit Prediction Scoring System) score of 100.0%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is GHSA-rvqx-wpfh-mfx7 in the CISA Known Exploited Vulnerabilities catalog?

Yes. GHSA-rvqx-wpfh-mfx7 (Langflow Missing Authentication Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2025-05-05. CISA required all US federal civilian agencies to remediate this vulnerability by 2025-05-26. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is GHSA-rvqx-wpfh-mfx7?

GHSA-rvqx-wpfh-mfx7 is classified as Missing Authentication (CWE-306), Code Injection (CWE-94). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for GHSA-rvqx-wpfh-mfx7?

A Nuclei detection template exists for GHSA-rvqx-wpfh-mfx7, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-rvqx-wpfh-mfx7 published, and has it been updated?

GHSA-rvqx-wpfh-mfx7 was published on June 17, 2025 and was last updated on June 29, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Exploitation Status

Actively exploited in the wild

Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2025-05-05 — including use in ransomware campaigns. Federal agencies were required to remediate by 2025-05-26.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.

How to detect GHSA-rvqx-wpfh-mfx7

A community-maintained Nuclei template exists for this CVE. You can scan for it directly:

nuclei -id ghsa-rvqx-wpfh-mfx7 -u https://target

Template: Langflow AI - Unauthenticated Remote Code Execution
Severity: critical
Impact: Unauthenticated attackers can execute arbitrary code through crafted POST requests to the /api/v1/validate/code endpoint, achieving complete server compromise.
Remediation: Upgrade to Langflow version 1.3.0 or later that properly validates user input before passing it to code execution functions.
