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-2019-19703 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.ktor:ktor-client-core (Maven): affected all versions; fixed in 1.3.0\n- io.ktor:ktor-client-core (Maven): affected all versions; fixed in 1.3.0\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-2019-19703/ (Markdown: https://insights.sbomify.com/CVE-2019-19703/index.md)","id":"CVE-2019-19703","markdown":"https://insights.sbomify.com/CVE-2019-19703/index.md","name":"CVE-2019-19703","record":{"aliases":["GHSA-xwgq-pcqx-hpmv"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ktor HTTP client","requires_auth":"none","summary":"The Ktor HTTP client leaks sensitive authorization headers to redirect targets, allowing attackers to steal credentials.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ktor","vendor":"jetbrains"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"In Ktor through 1.2.6, the client resends data from the HTTP Authorization header to a redirect location.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"URL Redirection to Untrusted Site (Open Redirect) in Ktor","id":"CVE-2019-19703","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"information_disclosure","year":"2019"},"n_packages":2,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2019-19704"},"packages":[{"ecosystem":"Maven","fixed":["1.3.0"],"introduced":["0"],"last_affected":[],"package":"io.ktor:ktor-client-core","purl":null,"source":"GHSA-xwgq-pcqx-hpmv"},{"ecosystem":"Maven","fixed":["1.3.0"],"introduced":["0"],"last_affected":[],"package":"io.ktor:ktor-client-core","purl":"pkg:maven/io.ktor/ktor-client-core","source":"GHSA-xwgq-pcqx-hpmv"}],"prev":{"headline":"Modoboa is vulnerable to an XML External Entity Injection (XXE)","id":"CVE-2019-19702"},"products":["n/a"],"published":"2019-12-10","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12736","kev_date_added":null,"published":"2019-10-02"},{"cvss_score":8.7,"headline":"SHA1 implementation in JetBrains Ktor Native 2.0.0 was returning the same value.","id":"CVE-2022-29930","kev_date_added":null,"published":"2022-05-12"},{"cvss_score":8.6,"headline":"XML external entity in Ktor","id":"CVE-2023-45612","kev_date_added":null,"published":"2023-10-09"},{"cvss_score":7.5,"headline":"Path traversal in Ktor","id":"CVE-2022-48476","kev_date_added":null,"published":"2023-04-24"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2021-43203","kev_date_added":null,"published":"2021-11-09"},{"cvss_score":6.8,"headline":"Security feature bypass in Ktor","id":"CVE-2023-45613","kev_date_added":null,"published":"2023-10-09"},{"cvss_score":6.5,"headline":"Other in n/a","id":"CVE-2020-26129","kev_date_added":null,"published":"2020-11-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"The Ktor HTTP client leaks sensitive authorization headers to redirect targets, allowing attackers to steal credentials.","url":"https://insights.sbomify.com/CVE-2019-19703/"}
