CVE-2026-39958

Summary

oma is a package manager for AOSC OS. Prior to 1.25.2, oma-topics is responsible for fetching metadata for testing repositories (topics) named "Topic Manifests" ({mirror}/debs/manifest/topics.json) from remote repository servers, registering them as APT source entries. However, the name field in said metadata were not checked for transliteration. In this case, a malicious party may supply a malformed Topic Manifest, which may cause malicious APT source entries to be added to /etc/apt/sources.list.d/atm.list as oma-topics finishes fetching and registering metadata. This vulnerability is fixed in 1.25.2.
