It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-43619 in the wild and no public exploit code.\n\nAffected product: RsyncProject rsync. 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-2026-43619/ (Markdown: https://insights.sbomify.com/CVE-2026-43619/index.md)","id":"CVE-2026-43619","markdown":"https://insights.sbomify.com/CVE-2026-43619/index.md","name":"CVE-2026-43619","record":{"aliases":["ALPINE-CVE-2026-43619","AZL-86985","BELL-CVE-2026-43619","CLSA-2026-1779959867","CLSA-2026-1780486587","CVE-2026-44509","DEBIAN-CVE-2026-43619","ECHO-2de0-1b04-bad9","GHSA-4h9m-w5ff-j735","GHSA-pwrq-5rj3-c43m","JLSEC-2026-630","UBUNTU-CVE-2026-43619"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"rsync file synchronization","requires_auth":"low_privilege","summary":"Local attackers can exploit a symlink race condition in rsync to modify arbitrary files outside the module boundary when chroot is disabled.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"rsync","vendor":"samba"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Rsync version 3.4.2 and prior contain symlink race condition vulnerabilities in path-based system calls including chmod, lchown, utimes, rename, unlink, mkdir, symlink, mknod, link, rmdir, and lstat that allow local attackers to redirect operations to files outside the exported rsync module.
