Description
IBM Langflow OSS 1.0.0 through 1.12.2 An authenticated flow author could write attacker-controlled file content into any directory writable by the service account, bypassing the platform's local file access isolation safeguard. Via a crafted on-disk index, the attacker could also read the contents of arbitrary files accessible to the service process — including configuration files, secrets, or database files stored under the application's data directory.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
The records we use list no fixed release for CVE-2026-97677. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
