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-2024-52590/ (Markdown: https://insights.sbomify.com/CVE-2024-52590/index.md)","id":"CVE-2024-52590","markdown":"https://insights.sbomify.com/CVE-2024-52590/index.md","name":"CVE-2024-52590","record":{"aliases":["GHSA-7vgr-p3vc-p4h2"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"product":"misskey","vendor":"misskey"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:N/SC:L/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Misskey is an open source, federated social media platform. In affected versions missing validation in `ApRequestService.signedGet` allows an attacker to create fake user profiles that appear to be from a different instance than the one where they actually exist. These profiles can be used to impersonate existing users from the target instance. Vulnerable Misskey instances will accept spoofed users as valid, allowing an attacker to impersonate users on another instance. Attackers have full control of the spoofed user and can post, renote, or otherwise interact like a real account. This issue has been addressed in version 2024.11.0-alpha.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.","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":"Missing validation allows spoofed profiles in Misskey","id":"CVE-2024-52590","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Missing validation allows spoofed profiles and notes in Misskey","id":"CVE-2024-52591"},"packages":[],"prev":{"headline":"Moderators can view Screened emails even when the “moderators view emails” option is disabled in Discourse","id":"CVE-2024-52589"},"products":["misskey"],"published":"2024-12-18","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 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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-12-19","vendors":["misskey-dev"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2024-52590/"}
