Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-39517 in the wild and no public exploit code.\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-2023-39517/ (Markdown: https://insights.sbomify.com/CVE-2023-39517/index.md)","id":"CVE-2023-39517","markdown":"https://insights.sbomify.com/CVE-2023-39517/index.md","name":"CVE-2023-39517","record":{"aliases":["GHSA-2h88-m32f-qh5m"],"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":"Attackers can execute arbitrary shell commands via malicious image links in Joplin due to insufficient HTML sanitization and lack of sandboxing.","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 in affected versions allows clicking on an untrusted image link to execute arbitrary shell commands. The HTML sanitizer (`packages/renderer/htmlUtils.ts::sanitizeHtml`) preserves `\u003cmap\u003e` `\u003carea\u003e` links. However, unlike `\u003ca\u003e` links, the `target` and `href` attributes are not removed. Additionally, because the note preview pane isn't sandboxed to prevent top navigation, links with `target` set to `_top` can replace the toplevel electron page. Because any toplevel electron page, with Joplin's setup, has access to `require` and can require node libraries, a malicious replacement toplevel page can import `child_process` and execute arbitrary shell commands. This issue has been fixed in commit 7c52c3e9a81a52ef1b42a951f9deb9d378d59b0f which is included in release version 2.12.8. 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":"none_known"},"has_fix":false,"headline":"Cross site scripting (XSS) when clicking on an untrusted `\u003cmap\u003e` link in Joplin","id":"CVE-2023-39517","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"social-media-skeleton stored Cross-site Scripting vulnerability","id":"CVE-2023-39518"},"packages":[],"prev":{"headline":"Stored Cross-Site-Scripting on data_sources.php debug html-block in Cacti","id":"CVE-2023-39516"},"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":"Safe mode Cross-site Scripting (XSS) vulnerability in Joplin","id":"CVE-2023-37898","kev_date_added":null,"published":"2024-06-21"},{"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"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["laurent22"]},"summary":"Attackers can execute arbitrary shell commands via malicious image links in Joplin due to insufficient HTML sanitization and lack of sandboxing.","url":"https://insights.sbomify.com/CVE-2023-39517/"}
