Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-39335 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- matrix-synapse (PyPI): affected all versions; fixed in 1.69.0\n- matrix-synapse (PyPI): affected all versions; fixed in 1.69.0\n- matrix-synapse (PyPI): affected all versions; fixed in 1.69.0\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-2022-39335/ (Markdown: https://insights.sbomify.com/CVE-2022-39335/index.md)","id":"CVE-2022-39335","markdown":"https://insights.sbomify.com/CVE-2022-39335/index.md","name":"CVE-2022-39335","record":{"aliases":["GHSA-45cj-f97f-ggwv","PYSEC-2023-65","UBUNTU-CVE-2022-39335"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Matrix homeserver","requires_auth":"low_privilege","summary":"Remote servers can improperly access authorization events in a room due to insufficient checks, potentially exposing sensitive data.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"synapse","vendor":"matrix"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. The Matrix Federation API allows remote homeservers to request the authorization events in a room. This is necessary so that a homeserver receiving some events can validate that those events are legitimate and permitted in their room. However, in versions of Synapse up to and including 1.68.0, a Synapse homeserver answering a query for authorization events does not sufficiently check that the requesting server should be able to access them. The issue was patched in Synapse 1.69.0. Homeserver administrators are advised to upgrade.","ecosystems":["PyPI"],"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":"Synapse does not apply enough checks to servers requesting auth events of events in a room","id":"CVE-2022-39335","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"missing_authorization","year":"2022"},"n_packages":3,"n_references":4,"next":{"headline":"Permission bypass due to incorrect configuration in github.com/dromara/hertzbeat","id":"CVE-2022-39337"},"packages":[{"ecosystem":"PyPI","fixed":["1.69.0"],"introduced":["0"],"last_affected":[],"package":"matrix-synapse","purl":null,"source":"GHSA-45cj-f97f-ggwv"},{"ecosystem":"PyPI","fixed":["1.69.0"],"introduced":["0"],"last_affected":[],"package":"matrix-synapse","purl":"pkg:pypi/matrix-synapse","source":"GHSA-45cj-f97f-ggwv"},{"ecosystem":"PyPI","fixed":["1.69.0"],"introduced":["0"],"last_affected":[],"package":"matrix-synapse","purl":"pkg:pypi/matrix-synapse","source":"PYSEC-2023-65"}],"prev":{"headline":"nextcloudcmd incorrectly trusts bad TLS certificates","id":"CVE-2022-39334"},"products":["synapse"],"published":"2023-05-26","related":[{"cvss_score":9.8,"headline":"Improper Verification of Cryptographic Signature in matrix-synapse","id":"CVE-2019-18835","kev_date_added":null,"published":"2019-11-07"},{"cvss_score":8.7,"headline":"Synapse allows a a malformed invite to break the invitee's `/sync`","id":"CVE-2024-52815","kev_date_added":null,"published":"2024-12-03"},{"cvss_score":8.2,"headline":"Synapse allows unsupported content types to lead to memory exhaustion","id":"CVE-2024-52805","kev_date_added":null,"published":"2024-12-03"},{"cvss_score":8.2,"headline":"Synapse can be forced to thumbnail unexpected file formats, invoking external, potentially untrustworthy decoders","id":"CVE-2024-53863","kev_date_added":null,"published":"2024-12-03"},{"cvss_score":7.5,"headline":"Synapse denial of service through media disk space consumption","id":"CVE-2024-37302","kev_date_added":null,"published":"2024-12-03"},{"cvss_score":7.5,"headline":"Matrix Synapse Authorization Error","id":"CVE-2018-12423","kev_date_added":null,"published":"2018-06-14"},{"cvss_score":7.5,"headline":"Matrix Synapse Security Filtering Flaw","id":"CVE-2018-12291","kev_date_added":null,"published":"2018-06-13"}],"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":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["matrix-org"]},"summary":"Remote servers can improperly access authorization events in a room due to insufficient checks, potentially exposing sensitive data.","url":"https://insights.sbomify.com/CVE-2022-39335/"}
