Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

AdminNeo versions from 4.6.2 up to but not including 5.5.0 are affected. A remote attacker who can reach the instance over the network can send a crafted POST request to the version endpoint, which poisons a shared cache file and causes subsequent page loads to return HTTP 500 errors for all users for about 24 hours. Upgrade to AdminNeo 5.5.0, which is the listed fixed version. The source also notes a workaround for users who cannot upgrade: make the adminneo.version file in the temp directory unwritable by the web server.
