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-2019-14537 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- yourls/yourls (Packagist): affected all versions; fixed in 1.7.4\n- yourls/yourls (Packagist): affected all versions; fixed in 1.7.4\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-2019-14537/ (Markdown: https://insights.sbomify.com/CVE-2019-14537/index.md)","id":"CVE-2019-14537","markdown":"https://insights.sbomify.com/CVE-2019-14537/index.md","name":"CVE-2019-14537","record":{"aliases":["GHSA-vf23-f26f-mjj9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"URL shortener","requires_auth":"none","summary":"Attackers can bypass login via type juggling in the API, allowing unauthorized access to YOURLS accounts.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"yourls","vendor":"yourls"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"YOURLS through 1.7.3 is affected by a type juggling vulnerability in the api component that can result in login bypass.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":"2019-08-07","github_poc":1,"max_poc_stars":8,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-08-07T11:25:39Z","kind":"github_poc","ref":"https://github.com/Wocanilo/CVE-2019-14537","stars":8,"title":"CVE-2019-14537  PoC"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Access of Resource Using Incompatible Type ('Type Confusion') in yourls/yourls","id":"CVE-2019-14537","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"auth_bypass","year":"2019"},"n_packages":2,"n_references":5,"next":{"headline":"Polymorphic Typing issue in FasterXML jackson-databind","id":"CVE-2019-14540"},"packages":[{"ecosystem":"Packagist","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"yourls/yourls","purl":null,"source":"GHSA-vf23-f26f-mjj9"},{"ecosystem":"Packagist","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"yourls/yourls","purl":"pkg:composer/yourls/yourls","source":"GHSA-vf23-f26f-mjj9"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2019-14535"},"products":["n/a"],"published":"2019-08-07","related":[{"cvss_score":8.8,"headline":"Cross-site Scripting (XSS) - Stored in yourls/yourls","id":"CVE-2021-3785","kev_date_added":null,"published":"2021-09-15"},{"cvss_score":6.6,"headline":"Cross-site Scripting (XSS) - Reflected in yourls/yourls","id":"CVE-2021-3783","kev_date_added":null,"published":"2021-09-15"},{"cvss_score":6.5,"headline":"Improper Restriction of Rendered UI Layers or Frames in yourls/yourls","id":"CVE-2021-3734","kev_date_added":null,"published":"2021-08-26"},{"cvss_score":5.4,"headline":"YOURLS Stored Cross Site Scripting (XSS)","id":"CVE-2020-27388","kev_date_added":null,"published":"2020-10-23"},{"cvss_score":5,"headline":"Information disclosure in n/a","id":"CVE-2011-3824","kev_date_added":null,"published":"2011-09-24"},{"cvss_score":3.5,"headline":"Cross-Site Request Forgery (CSRF) in yourls/yourls","id":"CVE-2022-0088","kev_date_added":null,"published":"2022-04-03"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can bypass login via type juggling in the API, allowing unauthorized access to YOURLS accounts.","url":"https://insights.sbomify.com/CVE-2019-14537/"}
