Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-37898 exists.\n\nAffected product: laurent22 joplin. 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-2023-37898/ (Markdown: https://insights.sbomify.com/CVE-2023-37898/index.md)","id":"CVE-2023-37898","markdown":"https://insights.sbomify.com/CVE-2023-37898/index.md","name":"CVE-2023-37898","record":{"aliases":["GHSA-hjmq-3qh4-g2r8"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joplin note taking app","requires_auth":"low_privilege","summary":"An XSS vulnerability in Joplin's safe mode allows attackers to execute arbitrary code via crafted notes, potentially compromising the local system.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"joplin","vendor":"joplin_project"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Joplin is a free, open source note taking and to-do application. A Cross-site Scripting (XSS) vulnerability allows an untrusted note opened in safe mode to execute arbitrary code. `packages/renderer/MarkupToHtml.ts` renders note content in safe mode by surrounding it with \u003cpre\u003e and \u003c/pre\u003e, without escaping any interior HTML tags. Thus, an attacker can create a note that closes the opening \u003cpre\u003e tag, then includes HTML that runs JavaScript. Because the rendered markdown iframe has the same origin as the toplevel document and is not sandboxed, any scripts running in the preview iframe can access the top variable and, thus, access the toplevel NodeJS `require` function. `require` can then be used to import modules like fs or child_process and run arbitrary commands. This issue has been addressed in version 2.12.9 and all users are advised to upgrade. There are no known workarounds for this vulnerability.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Safe mode Cross-site Scripting (XSS) vulnerability in Joplin","id":"CVE-2023-37898","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"feathersjs socket handler allows abusing implicit toString","id":"CVE-2023-37899"},"packages":[],"prev":{"headline":"Server-side Template Injection (SSTI) in grav","id":"CVE-2023-37897"},"products":["joplin"],"published":"2024-06-21","related":[{"cvss_score":9.8,"headline":"Joplin Vulnerable to Code Injection","id":"CVE-2022-23340","kev_date_added":null,"published":"2022-02-08"},{"cvss_score":9.7,"headline":"Joplin has a parsing error leading to Cross-site Scripting (XSS)","id":"CVE-2024-40643","kev_date_added":null,"published":"2024-09-09"},{"cvss_score":8.9,"headline":"Arbitrary code execution on click of PDF links in Joplin","id":"CVE-2023-45673","kev_date_added":null,"published":"2024-06-21"},{"cvss_score":8.8,"headline":"Privilege escalation in Joplin server via user patch endpoint","id":"CVE-2025-27134","kev_date_added":null,"published":"2025-04-30"},{"cvss_score":8.2,"headline":"Cross-site Scripting (XSS) when pasting HTML into the rich text editor in Joplin","id":"CVE-2023-38506","kev_date_added":null,"published":"2024-06-21"},{"cvss_score":8.2,"headline":"Cross site scripting (XSS) when clicking on an untrusted `\u003cmap\u003e` link in Joplin","id":"CVE-2023-39517","kev_date_added":null,"published":"2024-06-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["laurent22"]},"summary":"An XSS vulnerability in Joplin's safe mode allows attackers to execute arbitrary code via crafted notes, potentially compromising the local system.","url":"https://insights.sbomify.com/CVE-2023-37898/"}
