CVE-2017-15428

Status: ModifiedHigh (8.8)—💥 PoC

Insufficient data validation in V8 builtins string generator could lead to out of bounds read and write access in V8 in Google Chrome prior to 62.0.3202.94 and allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page.

CVSS

Exploitation probability (EPSS)

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.
