Attackers can send PUT requests to /songs/:idOrSlug, /tracks/:idOrSlug or /videos/:idOrSlug, or POST to /songs/:idOrSlug/merge, to alter genres, reassign tracks and merge songs.","modified":"2026-11-05T21:32:34.379060098Z","published":"2026-11-05T15:11:45.477Z","database_specific":{"cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/122xxx/CVE-2026-122327.json","cna_assigner":"VulnCheck"},"references":[{"type":"PACKAGE","url":"https://github.com/Arthi-chaud/Meelo"},{"type":"ARTICLE","url":"https://github.com/Arthi-chaud/Meelo/blob/v3.13.1/server/src/authentication/roles/roles.guard.ts#L48-L117"},{"type":"ARTICLE","url":"https://github.com/Arthi-chaud/Meelo/blob/v3.13.1/server/src/song/song.controller.ts#L275-L309"},{"type":"ARTICLE","url":"https://github.com/Arthi-chaud/Meelo/blob/v3.13.1/server/src/track/track.controller.ts#L145-L160"},{"type":"ARTICLE","url":"https://github.com/Arthi-chaud/Meelo/blob/v3.13.1/server/src/video/video.controller.ts#L131-L149"},{"type":"REPORT","url":"https://github.com/Arthi-chaud/Meelo/issues/2185"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/122xxx/CVE-2026-122327.json"},{"type":"ADVISORY","url":"https://hackmd.io/@hieund/meelo-catalog-metadata-write-missing-admin-authz"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-122327"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/meelo-through-3.13.1-missing-authorization-on-song-track-and-video-endpoints"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/arthi-chaud/meelo","events":[{"introduced":"0"},{"last_affected":"f49b4157121acdc0150dd093d79179ecbdc2219c"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"last_affected":"3.13.1"}]}]}}],"versions":["v3.13.1","v3.13.0","v3.12.0","v3.11.1","v3.11.0","v3.10.1","v3.10.0","v3.9.0","v3.8.3","v3.8.2","v3.8.1","v3.8.0","v3.7.0","v3.6.1","v3.6.0","v3.5.0","v3.4.1","v3.4.0","v3.3.0","v3.2.0","v3.1.0","v3.0.2","v3.0.1","v3.0.0","v2.4.0","v2.3.1","v2.3.0","v2.2.0","v2.1.0","v2.0.1","v2.0.0","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.9.0","v0.8.0","v0.7.0","v0.6.0","v0.5.0","v0.4.0","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-122327.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
