Technical Summary
This vulnerability affects Open Babel up to version 3.1.1 in the OBAtom::SetFormalCharge function located in include/openbabel/atom.h, specifically in the MOL2 File Handler component. The issue results in an out-of-bounds read, which can be triggered remotely without privileges or user interaction. The vulnerability has a CVSS 4.0 base score of 5.3 (medium severity). Although a patch commit has been identified (e23a224b8fd9d7c2a7cde9ef4ec6afb4c05aa08a), the vendor has not yet responded or officially released a fix.

The vulnerability does not require privileges or user interaction, increasing its risk. However, the impact is limited to information leakage or denial of service rather than code execution, consistent with the medium CVSS score.
Mitigation Recommendations
A patch commit has been identified for this vulnerability, but the vendor has not yet officially released a fix.
