Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-25636 in the wild and no public exploit code.\n\nAffected product: misskey-dev misskey. 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-2024-25636/ (Markdown: https://insights.sbomify.com/CVE-2024-25636/index.md)","id":"CVE-2024-25636","markdown":"https://insights.sbomify.com/CVE-2024-25636/index.md","name":"CVE-2024-25636","record":{"aliases":["GHSA-qqrm-9grj-6v32"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Misskey social platform","requires_auth":"low_privilege","summary":"Attackers can impersonate and take over remote accounts by uploading crafted Activity Streams documents to servers accepting arbitrary uploads.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"misskey","vendor":"misskey"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Misskey is an open source, decentralized social media platform with ActivityPub support. Prior to version 2024.2.0, when fetching remote Activity Streams objects, Misskey doesn't check that the response from the remote server has a `Content-Type` header value of the Activity Streams media type, which allows a threat actor to upload a crafted Activity Streams document to a remote server and make a Misskey instance fetch it, if the remote server accepts arbitrary user uploads. The vulnerability allows a threat actor to impersonate and take over an account on a remote server that satisfies all of the following properties: allows the threat actor to register an account; accepts arbitrary user-uploaded documents and places them on the same domain as legitimate Activity Streams actors; and serves user-uploaded document in response to requests with an `Accept` header value of the Activity Streams media type. Version 2024.2.0 contains a patch for the issue.","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":"Lack of media type verification of Activity Streams objects allows impersonation and takeover of remote accounts","id":"CVE-2024-25636","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2024"},"n_packages":0,"n_references":5,"next":{"headline":"Reflected XSS via X-October-Request-Handler Header","id":"CVE-2024-25637"},"packages":[],"prev":{"headline":"IDOR Vulnerability: Allowing Organization Owner to view the other Organizations API KEY and USERS","id":"CVE-2024-25635"},"products":["misskey"],"published":"2024-02-19","related":[{"cvss_score":9.3,"headline":"Misskey's Incomplete Patch of CVE-2024-52591 Leads to Forgery of Federated Notes","id":"CVE-2025-25306","kev_date_added":null,"published":"2025-03-10"},{"cvss_score":9.3,"headline":"Misskey's missing signature validation allows arbitrary users to impersonate any remote user.","id":"CVE-2023-49079","kev_date_added":null,"published":"2023-11-29"},{"cvss_score":9.2,"headline":"Misskey lacks proper authorization checks and input validation","id":"CVE-2026-28431","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":9.1,"headline":"Misskey vulnerable to improper authorization when accessing with third-party application","id":"CVE-2023-52139","kev_date_added":null,"published":"2023-12-29"},{"cvss_score":8.8,"headline":"Missing validation allows spoofed profiles in Misskey","id":"CVE-2024-52590","kev_date_added":null,"published":"2024-12-18"},{"cvss_score":8.8,"headline":"Missing validation allows spoofed profiles and notes in Misskey","id":"CVE-2024-52591","kev_date_added":null,"published":"2024-12-18"},{"cvss_score":8.8,"headline":"SQL injection of notes/search-by-tag","id":"CVE-2023-24812","kev_date_added":null,"published":"2023-02-22"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-08-15","vendors":["misskey-dev"]},"summary":"Attackers can impersonate and take over remote accounts by uploading crafted Activity Streams documents to servers accepting arbitrary uploads.","url":"https://insights.sbomify.com/CVE-2024-25636/"}
