CVE-2026-12567: CWE-59 Improper Link Resolution Before File Access ('Link Following') in Black Lantern Security BBOT
CVE-2026-12567 is a low-severity vulnerability in Black Lantern Security's BBOT version 2.0.0. The github_workflows module improperly handles user-controlled repository names when constructing local directory paths, failing to validate symbolic links. This allows a local attacker with access to the scan directory to plant a symlink at a predictable output path, causing workflow data to be written to an attacker-chosen location.
AI Analysis
Technical Summary
The vulnerability arises from improper link resolution before file access (CWE-59) in the github_workflows module of BBOT. Specifically, the module constructs local directory paths from user-controlled repository names without validating for symbolic links. An attacker who shares the scan directory can exploit this by placing a symlink at the expected output path, redirecting workflow data writes to arbitrary locations chosen by the attacker. This can lead to limited integrity impact as indicated by the CVSS vector, but no confidentiality or availability impact is reported.
Potential Impact
The impact is limited to integrity, where an attacker with local access can cause workflow data to be written to unintended locations by exploiting symlink following. There is no reported impact on confidentiality or availability. The CVSS score of 2.2 reflects a low-severity issue requiring local privileges and user interaction with high attack complexity.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is provided, restrict local access to the scan directory to trusted users only to prevent symlink planting.
