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-2026-19377 in the wild and no public exploit code.\n\nAffected product: Cato Client for Android. 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-2026-19377/ (Markdown: https://insights.sbomify.com/CVE-2026-19377/index.md)","id":"CVE-2026-19377","markdown":"https://insights.sbomify.com/CVE-2026-19377/index.md","name":"CVE-2026-19377","record":{"aliases":["GHSA-v76q-8hm2-wrx6"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cato Client","requires_auth":"none","summary":"A man-in-the-middle attacker can bypass certificate validation to impersonate a server and intercept or modify tunnel traffic.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Cato","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Improper certificate validation in the tunnel handshake in Cato Client allows a man-in-the-middle attacker to impersonate a Cato Point of Presence (PoP) server and intercept or modify tunnel traffic.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Improper certificate validation in Cato Client tunnel handshake","id":"CVE-2026-19377","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"code-projects Task Management System CommentSave.php cross site scripting","id":"CVE-2026-19378"},"packages":[],"prev":{"headline":"Uasoft Badaso File API api.php class permission","id":"CVE-2026-19376"},"products":["Cato Client for Android","Cato Client for Linux","Cato Client for Windows","Cato Client for iOS","Cato Client for macOS"],"published":"2026-10-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Cato Networks"]},"summary":"A man-in-the-middle attacker can bypass certificate validation to impersonate a server and intercept or modify tunnel traffic.","url":"https://insights.sbomify.com/CVE-2026-19377/"}
