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-2023-45673 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-2023-45673/ (Markdown: https://insights.sbomify.com/CVE-2023-45673/index.md)","id":"CVE-2023-45673","markdown":"https://insights.sbomify.com/CVE-2023-45673/index.md","name":"CVE-2023-45673","record":{"aliases":["GHSA-g8qx-5vcm-3x59"],"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 by tricking users into clicking links in untrusted PDFs within Joplin notes.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"joplin","vendor":"joplin_project"}],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Joplin is a free, open source note taking and to-do application. A remote code execution (RCE) vulnerability in affected versions allows clicking on a link in a PDF in an untrusted note to execute arbitrary shell commands. Clicking links in PDFs allows for arbitrary code execution because Joplin desktop: 1. has not disabled top redirection for note viewer iframes, and 2. and has node integration enabled. This is a remote code execution vulnerability that impacts anyone who attaches untrusted PDFs to notes and has the icon enabled. This issue has been addressed in version 2.13.3. 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":"Arbitrary code execution on click of PDF links in Joplin","id":"CVE-2023-45673","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection vulnerability in Farmbot-Web-App","id":"CVE-2023-45674"},"packages":[],"prev":{"headline":"Frigate unsafe deserialization in `load_config_with_no_duplicates` of `frigate/util/builtin.py`","id":"CVE-2023-45672"},"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":8.8,"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"},{"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["laurent22"]},"summary":"Attackers can execute arbitrary shell commands by tricking users into clicking links in untrusted PDFs within Joplin notes.","url":"https://insights.sbomify.com/CVE-2023-45673/"}
