CVE-2023-4877

Sensitive-data disclosure via unchecked font content

Published Sep 10, 2023 · Updated Sep 26, 2024

Sensitive information exposure in Inure App Manager before build92 allows local users to obtain data via crafted font content. TTFViewerActivity passed an intent-supplied content URI to the font parser without checking its MIME type or .ttf suffix. Exploitation requires a user to open attacker-supplied content, and the public record does not identify the specific data exposed.
