An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-82255 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gix-transport (crates.io): affected from 0.25.4; fixed in 0.56.0\n- gix-transport (crates.io): affected from 0.25.4; fixed in 0.56.0\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-2026-82255/ (Markdown: https://insights.sbomify.com/CVE-2026-82255/index.md)","id":"CVE-2026-82255","markdown":"https://insights.sbomify.com/CVE-2026-82255/index.md","name":"CVE-2026-82255","record":{"aliases":["DEBIAN-CVE-2026-82255","GHSA-2r3q-w7g9-8rpr","GHSA-9857-6mw7-fq2m","MINI-j3p4-f6j8-hc2q","UBUNTU-CVE-2026-82255"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Git client tool","requires_auth":"none","summary":"Attackers can steal authentication tokens by exploiting HTTP redirects in gitoxide, leading to credential exposure and potential account takeover.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"gitoxide versions from 0.25.4 contain an HTTP credential leak vulnerability in the curl-based transport backend where credentials are sent to attacker-controlled servers after HTTP redirects.
