Technical Analysis
CVE-2026-19303 affects IBM Langflow OSS versions 1.0.0 through 1.11.2. The vulnerability arises from improper restriction of file pathnames, enabling a remote authenticated attacker to delete arbitrary local files or directories outside intended boundaries. This is a path traversal issue (CWE-22) that can be exploited with low attack complexity and requires low privileges but no user interaction. The impact includes high integrity and availability damage, but no confidentiality loss is indicated.
Potential Impact
An attacker with authentication can delete arbitrary files or directories on the affected system, potentially disrupting service or causing data loss. The vulnerability does not affect confidentiality but poses a high risk to system integrity and availability.
Mitigation Recommendations
No patch or official fix information is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to trusted users only and monitor for suspicious activity related to file deletion operations.
