An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-4801 exists.\n\nAffected packages and fixed versions:\n- github.com/usememos/memos (Go): affected all versions; fixed in 0.9.1\n- github.com/usememos/memos (Go): affected all versions; fixed in 0.9.1\n- github.com/usememos/memos (Go): affected all versions; fixed in 0.9.1\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-2022-4801/ (Markdown: https://insights.sbomify.com/CVE-2022-4801/index.md)","id":"CVE-2022-4801","markdown":"https://insights.sbomify.com/CVE-2022-4801/index.md","name":"CVE-2022-4801","record":{"aliases":["GHSA-f83p-pg86-p922","GO-2022-1235"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Memos note-taking app","requires_auth":"none","summary":"Attackers can access or modify data due to insufficient access control granularity in the Memos application.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"memos","vendor":"usememos"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.0"},"cwes":[{"id":"CWE-1220","name":"Insufficient Granularity of Access Control"}],"description":"Insufficient Granularity of Access Control in GitHub repository usememos/memos prior to 0.9.1.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Insufficient Granularity of Access Control in usememos/memos","id":"CVE-2022-4801","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":"usememos:memos","products":["usememos:memos"],"type":"missing_authorization","year":"2022"},"n_packages":3,"n_references":2,"next":{"headline":"Authorization Bypass Through User-Controlled Key in usememos/memos","id":"CVE-2022-4802"},"packages":[{"ecosystem":"Go","fixed":["0.9.1"],"introduced":["0"],"last_affected":[],"package":"github.com/usememos/memos","purl":null,"source":"GHSA-f83p-pg86-p922"},{"ecosystem":"Go","fixed":["0.9.1"],"introduced":["0"],"last_affected":[],"package":"github.com/usememos/memos","purl":"pkg:golang/github.com/usememos/memos","source":"GHSA-f83p-pg86-p922"},{"ecosystem":"Go","fixed":["0.9.1"],"introduced":["0"],"last_affected":[],"package":"github.com/usememos/memos","purl":"pkg:golang/github.com/usememos/memos","source":"GO-2022-1235"}],"prev":{"headline":"Improper Verification of Source of a Communication Channel in usememos/memos","id":"CVE-2022-4800"},"products":["usememos/memos"],"published":"2022-12-28","related":[{"cvss_score":9.8,"headline":"Memos has Cross-Site Scripting (XSS) Vulnerability in Image URLs","id":"CVE-2025-50738","kev_date_added":null,"published":"2025-07-29"},{"cvss_score":9.8,"headline":"Memos Server-Side Request Forgery (SSRF)","id":"CVE-2025-22952","kev_date_added":null,"published":"2025-02-27"},{"cvss_score":9.8,"headline":"Stored XSS in usememos/memos","id":"CVE-2023-0109","kev_date_added":null,"published":"2024-11-15"},{"cvss_score":9.8,"headline":"Improper Access Control in usememos/memos","id":"CVE-2023-4696","kev_date_added":null,"published":"2023-09-01"},{"cvss_score":9.8,"headline":"Cross-site Scripting (XSS) - Stored in usememos/memos","id":"CVE-2022-4866","kev_date_added":null,"published":"2022-12-31"},{"cvss_score":9.8,"headline":"Improper Handling of Values in usememos/memos","id":"CVE-2022-4851","kev_date_added":null,"published":"2022-12-29"},{"cvss_score":9.8,"headline":"Improper Restriction of Excessive Authentication Attempts in usememos/memos","id":"CVE-2022-4797","kev_date_added":null,"published":"2022-12-28"}],"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":"Go Vulnerability Database","prefix":"GO"},{"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-10","vendors":["usememos"]},"summary":"Attackers can access or modify data due to insufficient access control granularity in the Memos application.","url":"https://insights.sbomify.com/CVE-2022-4801/"}
