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-2026-70454 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-2026-70454/ (Markdown: https://insights.sbomify.com/CVE-2026-70454/index.md)","id":"CVE-2026-70454","markdown":"https://insights.sbomify.com/CVE-2026-70454/index.md","name":"CVE-2026-70454","record":{"aliases":["ALPINE-CVE-2026-70454","AZL-95777","BELL-CVE-2026-70454","DEBIAN-CVE-2026-70454","ECHO-8d10-95d4-4155","GHSA-3c3x-ww2w-5r5p","ROOT-OS-DEBIAN-11-CVE-2026-70454","UBUNTU-CVE-2026-70454"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"rsync file transfer","requires_auth":"none","summary":"Attackers can intercept rsync sessions by bypassing TLS certificate validation in SSL or stunnel modes, allowing decryption or tampering of data.","user_interaction":"required","vuln_class":"security_feature_bypass"},"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:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"rsync 3.2.0 through 3.2.3 (openssl mode) and rsync-ssl through 3.4.4 (stunnel mode) contain a TLS certificate validation vulnerability that allows on-path attackers to intercept encrypted sessions by presenting self-signed or otherwise invalid certificates.
