> DESCRIPTION

A security vulnerability has been detected in proma-ai Proma up to 0.19.37. Affected is the function resolveTargetPath of the file apps/electron/src/main/lib/file-preview-service.ts of the component File Preview Service. Such manipulation of the argument file_path leads to path traversal. Local access is required to approach this attack. The exploit has been disclosed publicly and may be used. Upgrading to version 0.19.52 is able to address this issue. The name of the patch is b7bf78ab74b1552c92fc98c7db9a8a8d92c631df. It is suggested to upgrade the affected component. The PoC's candidateBasePaths parameter name does not match the current IPC API (0.19.52 uses FileAccessOptions with internal getPreviewCandidateBasePaths()). The reporter likely targeted 0.16.3 where the IPC handler accepted raw string[] base paths. The core vulnerability - basename-collision fallback - is independent of the parameter name and is confirmed in source.
