AI Analysis
Technical Summary
IBM Langflow OSS versions 1.0.0 through 1.10.1 contain an access control vulnerability (CWE-639) that permits authenticated users to access and manipulate build jobs belonging to other users. This occurs due to improper access control mechanisms on log retrieval and unauthenticated build endpoints, potentially allowing unauthorized access to sensitive build job data. The vulnerability has been assigned CVE-2026-12945 and is rated with high severity. No official patches or fixes have been provided, and no exploitation in the wild has been reported.
Potential Impact
The vulnerability allows authenticated users to access and manipulate other users' build jobs, which can lead to unauthorized disclosure of sensitive information (high confidentiality impact) and limited denial of service (low availability impact). There is no impact on integrity reported. No known exploitation has been observed in the wild.
Mitigation Recommendations
No official patches or fixes are currently available for this vulnerability. Users should monitor vendor advisories for updates. Until a fix is released, restrict access to the affected IBM Langflow OSS versions to trusted users only and consider additional access control measures to limit exposure.
