Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-49090 in the wild and no public exploit code.\n\nAffected product: Matrix specification. 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-2025-49090/ (Markdown: https://insights.sbomify.com/CVE-2025-49090/index.md)","id":"CVE-2025-49090","markdown":"https://insights.sbomify.com/CVE-2025-49090/index.md","name":"CVE-2025-49090","record":{"aliases":["GHSA-jhc3-vch4-27rh","openSUSE-SU-2025:15436-1"],"analysis":{"component_type":"other","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Matrix specification","requires_auth":"low_privilege","summary":"Deficient state resolution in older Matrix specifications allows attackers to bypass security controls, requiring specification upgrades.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-642","name":"External Control of Critical State Data"}],"description":"The Matrix specification before 1.16 (i.e., with a room version before 12 and State Resolution before 2.1) has deficient state resolution.","ecosystems":["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":"Business logic in Matrix specification","id":"CVE-2025-49090","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2025"},"n_packages":1,"n_references":4,"next":{"headline":"Command injection in Konsole","id":"CVE-2025-49091"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.136.0-1.1"],"introduced":["0"],"last_affected":[],"package":"matrix-synapse","purl":"pkg:rpm/opensuse/matrix-synapse\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2025:15436-1"}],"prev":{"headline":"Path traversal in n/a","id":"CVE-2025-49089"},"products":["Matrix specification"],"published":"2025-10-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2025-10-02","vendors":["Matrix"]},"summary":"Deficient state resolution in older Matrix specifications allows attackers to bypass security controls, requiring specification upgrades.","url":"https://insights.sbomify.com/CVE-2025-49090/"}
