Summary
The AceIDE WordPress plugin through 2.6.2 does not sanitise or validate the user input which is appended to system paths before using it in various actions, such as to read arbitrary files from the server. This allows high privilege users such as administrator to access any file on the web server outside of the blog directory via a path traversal attack.
Exploit prediction
1.57% chance of exploitation in the next 30 days, higher than 75% of all scored CVEs (FIRST EPSS, 2026-11-08).
