Public exploitAvailableProof of concept on GitHub (unverified)

The Theme My Login plugin for WordPress is vulnerable to privilege escalation via account takeover in versions up to, and including, 7.2.1. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords on multi-site setups in certain configurations.

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.
