Vulnerability Database

Live CVE intelligence for researchers and engineers — ranked by real exploitation signals. The vulnerabilities most likely to be exploited (EPSS), those confirmed actively exploited (CISA KEV), and recent advisories across every major package ecosystem. Look up any CVE at /vulnerability/CVE-YYYY-NNNNN.

Know the ID? Go straight to /vulnerability/CVE-2021-44228 or any CVE / GHSA.

1,756 vulnerabilities are confirmed actively exploited in the CISA KEV catalog, with 30 added in the last 30 days (down 17 month-over-month). 806 CVEs carry an EPSS exploitation probability above 90%, led by CVE-2025-53770 at 100%. 361 KEV entries are linked to known ransomware campaigns.

Exploitability quadrant

EPSS × CVSS · CISA KEV CVEs

Actively-exploited CVEs by likelihood × impact. Top-right = patch first.

99 CISA KEV (actively-exploited) CVEs plotted by exploitation likelihood (EPSS, x-axis) against impact (CVSS, y-axis). 13 sit in the top-right "patch first" zone — at least 50% EPSS probability and CVSS 7.0+ — making them the highest-priority vulnerabilities to remediate.

CISA added 429 CVEs to its Known Exploited Vulnerabilities catalog over the last 18 months, including 26 in Oct 26. Each is confirmed exploited in the wild.

Exploitability landscape

all scored CVEs · EPSS bands

How likely the CVE universe is to be exploited (log scale).

Across all CVEs with an EPSS score: 806 are ≥ 90%, 3,527 are 50–90%, 13,008 are 10–50%, 377,908 are < 10% likely to be exploited within 30 days. The landscape is heavily skewed — the vast majority fall below 10%, so EPSS is effective at isolating the small set of genuinely high-risk CVEs.

Most actively exploited — right now

The vulnerabilities under the most active exploitation right now — all confirmed in the CISA Known Exploited Vulnerabilities catalog and ranked by EPSS exploitation probability — are led by CVE-2015-3306 (ProFTPD Improper Access Control, 99% EPSS), CVE-2015-5477 ( ISC BIND Data Processing Errors, 99% EPSS), CVE-2026-72898 (Metabase SQL Injection, 97% EPSS). 1 of the top 8 are linked to known ransomware campaigns.

  1. 1
    CVE-2015-330699% EPSS

    ProFTPD Improper Access Control Vulnerability — ProFTPD ProFTPD

    ProFTPD contains an improper access control vulnerability that could allow remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands.

  2. 2
    CVE-2015-547799% EPSS

    ISC BIND Data Processing Errors Vulnerability — ISC BIND

    ISC BIND contains a data processing errors vulnerability that could allow remote attackers to cause a denial of service via TKEY queries.

  3. 3

From there, the attacker could change the application configuration, steal stored credentials for the connected databases, read any data accessible through those connections, and export data.

  4. 4
    CVE-2016-308196% EPSS

    Apache Struts Command Injection Vulnerability — Apache Struts

    Apache Struts contains a command injection vulnerability that could allow remote attackers to execute arbitrary code via method:prefix when Dynamic Method Invocation is enabled.

  5. 5
    CVE-2026-8570692% EPSS

    GitLab Community Edition and Enterprise Edition Path Traversal Vulnerability — GitLab Community Edition and Enterprise Edition

    GitLab Community Edition and Enterprise Edition contains a path traversal vulnerability that allows an unauthenticated user to read arbitrary files due to an improper path confinement and missing authentication enforcement in the repository commits API.

  6. 6
    CVE-2026-6307790% EPSSRansomware

    JetBrains TeamCity Deserialization of Untrusted Data Vulnerability — JetBrains TeamCity
