CVE-2024-7738

Arbitrary file read via path traversal

Published Aug 13, 2024 · Updated Aug 13, 2024

Path traversal in yzane Markdown PDF 1.5.0 allows local users to read arbitrary files through a crafted Markdown document. The public record identifies the Markdown File Handler but does not disclose the path-processing function or how traversal sequences escape the intended directory. Exploitation requires low-privileged local access and exposes files readable by the extension process, with no reported write or code-execution impact.
