An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-109348 exists.\n\nAffected product: GitoxideLabs gix-mailmap. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-109348/ (Markdown: https://insights.sbomify.com/CVE-2026-109348/index.md)","id":"CVE-2026-109348","markdown":"https://insights.sbomify.com/CVE-2026-109348/index.md","name":"CVE-2026-109348","record":{"aliases":["DEBIAN-CVE-2026-109348","GHSA-mjrq-mxwp-ch57","GHSA-pmpw-wwcm-r8rc","UBUNTU-CVE-2026-109348"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitoxide mailmap library","requires_auth":"none","summary":"Attackers can cause CPU exhaustion and block Git operations by committing a crafted .mailmap file to the repository.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-407","name":"Inefficient Algorithmic Complexity"}],"description":"Gitoxide gix-mailmap before 0.35.0 contains a denial of service vulnerability that allows attackers to exhaust CPU through quadratic-time parsing in Snapshot::from_bytes.
