flowisenpmDescription
Flowise is a drag & drop user interface to build a customized large language model flow. In version 1.4.3 of Flowise, the /api/v1/openai-assistants-file endpoint in index.ts is vulnerable to arbitrary file read due to lack of sanitization of the fileName body parameter. No known patches for this issue are available.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for flowise, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of flowise for GHSA-h997-3fxj-p5j8. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
