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-2022-39380 in the wild and no public exploit code.\n\nAffected product: wireapp wire-webapp. 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-2022-39380/ (Markdown: https://insights.sbomify.com/CVE-2022-39380/index.md)","id":"CVE-2022-39380","markdown":"https://insights.sbomify.com/CVE-2022-39380/index.md","name":"CVE-2022-39380","record":{"aliases":["GHSA-v5mf-358q-w7m4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Wire web application","requires_auth":"none","summary":"Attackers can cause a denial of service in Wire web-app by sending specific Markdown messages that crash the chat history rendering.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"wire-webapp","vendor":"wire"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"}],"description":"Wire web-app is part of Wire communications. Versions prior to 2022-11-02 are subject to Improper Handling of Exceptional Conditions. In the wire-webapp, certain combinations of Markdown formatting can trigger an unhandled error in the conversion to HTML representation. The error makes it impossible to display the affected chat history, other conversations are not affected. The issue has been fixed in version 2022-11-02 and is already deployed on all Wire managed services. On-premise instances of wire-webapp need to be updated to docker tag 2022-11-02-production.0-v0.31.9-0-337e400 or wire-server 2022-11-03 (chart/4.26.0), so that their applications are no longer affected. As a workaround, you may use an iOS or Android client and delete the corresponding message from the history OR write 30 or more messages into the affected conversation to prevent the client from further rendering of the corresponding message. When attempting to retrieve messages from the conversation history, the error will continue to occur once the malformed message is part of the result.","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":"wire-webapp contains Improper Handling of Exceptional Conditions leading to a DoS via Markdown Rendering","id":"CVE-2022-39380","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Unchecked Return Value to NULL Pointer Dereference in PDFDocumentHandler.cpp","id":"CVE-2022-39381"},"packages":[],"prev":{"headline":"Fluentd vulnerable to remote code execution due to insecure deserialization (in non-default configuration)","id":"CVE-2022-39379"},"products":["wire-webapp"],"published":"2023-01-27","related":[{"cvss_score":9.6,"headline":"Cross Site Scripting in Wire Messages","id":"CVE-2022-29168","kev_date_added":null,"published":"2022-06-25"},{"cvss_score":9.6,"headline":"Cross Site Scripting in Wire Webapp","id":"CVE-2022-24799","kev_date_added":null,"published":"2022-04-20"},{"cvss_score":8.8,"headline":"XSS through createObjectURL","id":"CVE-2021-32683","kev_date_added":null,"published":"2021-06-15"},{"cvss_score":7.1,"headline":"Entering code in App Lock modal sends input to conversation","id":"CVE-2021-21400","kev_date_added":null,"published":"2021-04-02"},{"cvss_score":6,"headline":"wire-webapp has no database deletion on client logout","id":"CVE-2025-48066","kev_date_added":null,"published":"2025-05-22"},{"cvss_score":4.4,"headline":"Expired Ephemeral Messages not reliably removed in wire-webapp","id":"CVE-2022-23605","kev_date_added":null,"published":"2022-02-04"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-10","vendors":["wireapp"]},"summary":"Attackers can cause a denial of service in Wire web-app by sending specific Markdown messages that crash the chat history rendering.","url":"https://insights.sbomify.com/CVE-2022-39380/"}
