CVE Tracker

Top older CVEs (2015–2025)

Old vulnerabilities that attackers still use. Ranked by the estimated chance of exploitation in the next 30 days.

EPSS is likelihood, a statistical probability, not a certainty. KEV means CISA has confirmed exploitation. PoC ref means NVD lists an exploit-tagged link for the CVE, or ThreatWire marks a PoC. Links are unverified and ThreatWire has not run any of them.

Sources: FIRST EPSS, NVD and the CISA KEV catalogue. EPSS scores of 16 Oct 2026. Data last updated 17 Oct 2026. Covers every older CVE in KEV plus older CVEs with EPSS of 90% or more; CVSS fills in over the next daily updates, and "No CVSS" means NVD data is not loaded yet. Search the full tracker
