{"id":"GHSA-vmwx-m75v-qvch","aliases":["CVE-2026-53634"],"title":"Sharp Missing Authorization Check in Quick Creation Command Endpoints","description":"### Impact\nThe create and store endpoints of the Quick Creation Command feature did not enforce any authorization check. An authenticated Sharp user without create permission on a given entity could bypass the authorization layer and either retrieve the creation form or submit new records for that entity, as long as it had a Quick Creation Command handler configured.\n\n### Patches\nYes. The fix is included in version 9.22.3. Users should upgrade to that version or later.\n\n### Workarounds\nRemove or disable Quick Creation Command handlers (quickCreationCommandHandler()) on any entity list where unauthorized access is a concern, until an upgrade is possible.\n\n### Resources\n[PR #729](https://github.com/code16/sharp/pull/729)","severity":"medium","score":4.3,"published":"2026-07-08T20:24:36.000Z","modified":"2026-07-08T20:30:17.681Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"code16/sharp","ranges":[{"events":[{"introduced":"9.0.0"},{"fixed":"9.22.3"}],"type":"ECOSYSTEM"}],"versions":["v9.0.0","v9.0.1","v9.0.2","v9.0.3","v9.0.4","v9.0.5","v9.0.6","v9.0.7","v9.0.8","v9.0.9","v9.1.0","v9.1.1","v9.1.2","v9.10.0","v9.10.1","v9.10.2","v9.11.0","v9.11.1","v9.12.0","v9.13.0","v9.13.1","v9.14.0","v9.14.1","v9.14.2","v9.14.3","v9.14.4","v9.15.0","v9.15.1","v9.16.0","v9.16.1","v9.17.0","v9.17.1","v9.18.0","v9.19.0","v9.19.1","v9.19.2","v9.19.3","v9.2.0","v9.2.1","v9.2.2","v9.2.3","v9.2.4","v9.2.5","v9.2.6","v9.2.7","v9.2.8","v9.20.0","v9.21.0","v9.21.1","v9.21.2","v9.22.0","v9.22.1","v9.22.2","v9.3.0","v9.3.1","v9.3.2","v9.3.3","v9.3.4","v9.3.5","v9.3.6","v9.3.7","v9.4.0","v9.4.1","v9.5.0","v9.5.1","v9.5.2","v9.6.0","v9.6.1","v9.6.2","v9.6.3","v9.6.4","v9.6.5","v9.6.6","v9.7.0","v9.7.1","v9.7.2","v9.7.3","v9.8.0","v9.8.1","v9.9.0"],"fixed":["9.22.3"]}],"references":["https://github.com/code16/sharp/security/advisories/GHSA-vmwx-m75v-qvch","https://nvd.nist.gov/vuln/detail/CVE-2026-53634","https://github.com/code16/sharp/pull/729","https://github.com/code16/sharp/commit/aa18a85fd8fef830988a336cad2278986729d21a","https://github.com/code16/sharp","https://github.com/code16/sharp/releases/tag/v9.22.3"],"sources":[{"name":"OSV","id":"GHSA-vmwx-m75v-qvch","modified":"2026-07-08T20:30:17.681866029Z","url":"https://osv.dev/vulnerability/GHSA-vmwx-m75v-qvch"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3}]}
