An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-57818 in the wild and no public exploit code.\n\nAffected product: Apache Cxf. 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-2026-57818/ (Markdown: https://insights.sbomify.com/CVE-2026-57818/index.md)","id":"CVE-2026-57818","markdown":"https://insights.sbomify.com/CVE-2026-57818/index.md","name":"CVE-2026-57818","record":{"aliases":["GHSA-4qr2-3mpc-grqm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache CXF","requires_auth":"none","summary":"Attackers can replay OAuth2 authorization codes via a race condition to obtain multiple valid access tokens, compromising user accounts.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"cxf","vendor":"apache"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"A race condition in JCacheCodeDataProvider allows an attacker to redeem a single authorization code multiple times via concurrent requests, resulting in the issuance of multiple distinct, valid access tokens.
