An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-15926 in the wild and no public exploit code.\n\nAffected product: Rocket.chat Rocket.chat. 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-2020-15926/ (Markdown: https://insights.sbomify.com/CVE-2020-15926/index.md)","id":"CVE-2020-15926","markdown":"https://insights.sbomify.com/CVE-2020-15926/index.md","name":"CVE-2020-15926","record":{"aliases":["GHSA-r5wc-mg37-wmg8"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Rocket.Chat","requires_auth":"none","summary":"Attackers can execute arbitrary code on client systems by sending specially crafted messages in Rocket.Chat channels or direct messages.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"rocket.chat","vendor":"rocket.chat"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Rocket.Chat through 3.4.2 allows XSS where an attacker can send a specially crafted message to a channel or in a direct message to the client which results in remote code execution on the client side.","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 in n/a","id":"CVE-2020-15926","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"rocket.chat:rocket.chat","products":["rocket.chat:rocket.chat"],"type":"xss","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"SQL injection in n/a","id":"CVE-2020-15927"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2020-15925"},"products":["n/a"],"published":"2020-08-18","related":[{"cvss_score":9.8,"headline":"Auth bypass in Rocket.Chat","id":"CVE-2026-58066","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":9.8,"headline":"SQL injection in Rocket.Chat","id":"CVE-2026-29198","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":9.8,"headline":"Security feature bypass in Rocket.Chat","id":"CVE-2023-28316","kev_date_added":null,"published":"2023-05-09"},{"cvss_score":9.8,"headline":"Command injection in Rocket.chat - Electron Desktop","id":"CVE-2022-44567","kev_date_added":null,"published":"2022-12-23"},{"cvss_score":9.8,"headline":"Code injection in Rocket.Chat server","id":"CVE-2021-22910","kev_date_added":null,"published":"2021-08-09"},{"cvss_score":9.8,"headline":"Code injection in Rocket.Chat server","id":"CVE-2021-22911","kev_date_added":null,"published":"2021-05-27"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-29594","kev_date_added":null,"published":"2020-12-30"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code on client systems by sending specially crafted messages in Rocket.Chat channels or direct messages.","url":"https://insights.sbomify.com/CVE-2020-15926/"}
