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-2022-21650 exists.\n\nAffected product: convos-chat convos. 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-2022-21650/ (Markdown: https://insights.sbomify.com/CVE-2022-21650/index.md)","id":"CVE-2022-21650","markdown":"https://insights.sbomify.com/CVE-2022-21650/index.md","name":"CVE-2022-21650","record":{"aliases":["GHSA-mm2v-4v7g-m695"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Convos chat application","requires_auth":"low_privilege","summary":"Attackers can execute malicious scripts via stored XSS by uploading HTML files, affecting Convos chat users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"convos","vendor":"convos"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Convos is an open source multi-user chat that runs in a web browser. You can't use SVG extension in Convos' chat window, but you can upload a file with an .html extension. By uploading an SVG file with an html extension the upload filter can be bypassed. This causes Stored XSS. Also, after uploading a file the XSS attack is triggered upon a user viewing the file. Through this vulnerability, an attacker is capable to execute malicious scripts. Users are advised to update as soon as possible.","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":"Stored XSS via html file upload in convos","id":"CVE-2022-21650","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2022"},"n_packages":0,"n_references":4,"next":{"headline":"Open redirect in shopware","id":"CVE-2022-21651"},"packages":[],"prev":{"headline":"Stored XSS via attribute in convos","id":"CVE-2022-21649"},"products":["convos"],"published":"2022-01-04","related":[{"cvss_score":7.6,"headline":"Stored XSS via attribute in convos","id":"CVE-2022-21649","kev_date_added":null,"published":"2022-01-04"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2021-42584","kev_date_added":null,"published":"2021-12-17"},{"cvss_score":5.3,"headline":"Weak cryptography in n/a","id":"CVE-2020-14423","kev_date_added":null,"published":"2020-06-18"}],"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":"2025-04-22","vendors":["convos-chat"]},"summary":"Attackers can execute malicious scripts via stored XSS by uploading HTML files, affecting Convos chat users.","url":"https://insights.sbomify.com/CVE-2022-21650/"}
