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-2022-36059 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- matrix-js-sdk (npm): affected all versions; fixed in 19.4.0\n- matrix-js-sdk (npm): affected all versions; fixed in 19.4.0\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-2022-36059/ (Markdown: https://insights.sbomify.com/CVE-2022-36059/index.md)","id":"CVE-2022-36059","markdown":"https://insights.sbomify.com/CVE-2022-36059/index.md","name":"CVE-2022-36059","record":{"aliases":["CLEANSTART-2024-IV81629","DEBIAN-CVE-2022-36059","GHSA-rfv9-x7hh-xc32","UBUNTU-CVE-2022-36059","openSUSE-SU-2024:12294-1","openSUSE-SU-2024:12295-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Matrix JavaScript SDK","requires_auth":"none","summary":"Prototype pollution in matrix-js-sdk allows attackers to corrupt runtime data or disrupt client functionality via crafted events.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"javascript_sdk","vendor":"matrix"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 19.4.0 events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This issue has been fixed in matrix-js-sdk 19.4.0 and users are advised to upgrade. Users unable to upgrade may mitigate this issue by redacting applicable events, waiting for the sync processor to store data, and restarting the client. Alternatively, redacting the applicable events and clearing all storage will often fix most perceived issues. In some cases, no workarounds are possible.","ecosystems":["npm","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Prototype pollution in matrix-js-sdk","id":"CVE-2022-36059","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2022"},"n_packages":4,"n_references":1,"next":{"headline":"Prototype pollution in matrix-react-sdk","id":"CVE-2022-36060"},"packages":[{"ecosystem":"npm","fixed":["19.4.0"],"introduced":["0"],"last_affected":[],"package":"matrix-js-sdk","purl":null,"source":"GHSA-rfv9-x7hh-xc32"},{"ecosystem":"npm","fixed":["19.4.0"],"introduced":["0"],"last_affected":[],"package":"matrix-js-sdk","purl":"pkg:npm/matrix-js-sdk","source":"GHSA-rfv9-x7hh-xc32"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.11.4-1.1"],"introduced":["0"],"last_affected":[],"package":"element-desktop","purl":"pkg:rpm/opensuse/element-desktop\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:12294-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.11.4-1.1"],"introduced":["0"],"last_affected":[],"package":"element-web","purl":"pkg:rpm/opensuse/element-web\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:12295-1"}],"prev":{"headline":"elrond-go MultiESDTNFTTransfer call on a SC address with missing function name","id":"CVE-2022-36058"},"products":["matrix-js-sdk"],"published":"2023-03-28","related":[{"cvss_score":8.6,"headline":"Matrix JavaScript SDK vulnerable to key/device identifier confusion in SAS verification","id":"CVE-2022-39250","kev_date_added":null,"published":"2022-09-29"},{"cvss_score":8.6,"headline":"Matrix Javascript SDK vulnerable to Olm/Megolm protocol confusion","id":"CVE-2022-39251","kev_date_added":null,"published":"2022-09-28"},{"cvss_score":8.2,"headline":"Prototype pollution in matrix-js-sdk","id":"CVE-2023-28427","kev_date_added":null,"published":"2023-03-28"},{"cvss_score":7.5,"headline":"Matrix Javascript SDK vulnerable to impersonation via forwarded Megolm sessions","id":"CVE-2022-39249","kev_date_added":null,"published":"2022-09-28"},{"cvss_score":5.9,"headline":"matrix-js-sdk can be tricked into disclosing E2EE room keys to a participating homeserver","id":"CVE-2021-40823","kev_date_added":null,"published":"2021-09-13"},{"cvss_score":5,"headline":"matrix-js-sdk vulnerable to invisible eavesdropping in group calls","id":"CVE-2023-29529","kev_date_added":null,"published":"2023-04-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2025-02-18","vendors":["matrix-org"]},"summary":"Prototype pollution in matrix-js-sdk allows attackers to corrupt runtime data or disrupt client functionality via crafted events.","url":"https://insights.sbomify.com/CVE-2022-36059/"}
