The auto-completion plugin in Ametys CMS before 4.5.0 allows a remote unauthenticated attacker to read documents such as plugins/web/service/search/auto-completion/<domain>/en.xml (and similar pathnames for other languages), which contain all characters typed by all users, including the content of private pages. For example, a private page may contain usernames, e-mail addresses, and possibly passwords.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
