Summary

The file upload plugin in Adminer and AdminerEvo allows an attacker to upload a file with a table name of “..” to the root of the Adminer directory. The attacker can effectively guess the name of the uploaded file and execute it. Adminer is no longer supported, but this issue was fixed in AdminerEvo version 4.8.3.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
