Detailsinfo A vulnerability classified as critical was found in AOSC oma up to 1.25.0. This vulnerability affects an unknown code of the file {mirror}/debs/manifest/topics.json. The manipulation of the argument name with an unknown input leads to a crlf injection vulnerability. The CWE definition for the vulnerability is CWE-93.

As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes: 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. The advisory is available at github.com. This vulnerability was named CVE-2026-39958 since 04/08/2026. The exploitation appears to be difficult.
