Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-54315 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-2025-54315/ (Markdown: https://insights.sbomify.com/CVE-2025-54315/index.md)","id":"CVE-2025-54315","markdown":"https://insights.sbomify.com/CVE-2025-54315/index.md","name":"CVE-2025-54315","record":{"aliases":["GHSA-j8g5-8x38-5xqp"],"analysis":{"component_type":"other","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Matrix specification","requires_auth":"low_privilege","summary":"The Matrix specification lacks create event uniqueness, allowing attackers to manipulate room state or integrity.","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-837","name":"Improper Enforcement of a Single, Unique Action"}],"description":"The Matrix specification before 1.16 (i.e., with a room version before 12) lacks create event uniqueness.","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":"Business logic in Matrix specification","id":"CVE-2025-54315","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Logpoint","id":"CVE-2025-54316"},"packages":[],"prev":{"headline":"Command injection in Thor","id":"CVE-2025-54314"},"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":"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":"The Matrix specification lacks create event uniqueness, allowing attackers to manipulate room state or integrity.","url":"https://insights.sbomify.com/CVE-2025-54315/"}
