CVE-2026-21621

Incorrect Authorization vulnerability in hexpm hexpm/hexpm 'Elixir.HexpmWeb.API.OAuthController' module allows Privilege Escalation. An API key created with read-only permissions domain: "api", resource: "read" can be escalated to full write access under specific conditions. When exchanging a...

parse-server's endpoint `/loginAs` allows `readOnlyMasterKey` to gain full read and write access as any user

Impact The readOnlyMasterKey can call POST /loginAs to obtain a valid session token for any user. This allows a read-only credential to impersonate arbitrary users with full read and write access to their data. Any Parse Server deployment that uses readOnlyMasterKey is affected. Patches The fix...
