CVE-2020-8218 has a CVSS score of 7.2/10, rated HIGH. Immediate patching is strongly recommended.

Which products are affected by CVE-2020-8218?

Affected package information for CVE-2020-8218 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2020-8218?

No patch has shipped for CVE-2020-8218 yet — track the ivanti connect secure advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2020-8218 across my infrastructure?

Inventory every ivanti connect secure deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2020-8218 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2020-8218?

O3 detects and blocks CVE-2020-8218 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2020-8218 actively exploited in the wild?

Yes. There are 6 known exploit references for CVE-2020-8218, including 5 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2020-8218?

CVE-2020-8218 has an EPSS (Exploit Prediction Scoring System) score of 32.3%, placing it in the 98th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score warrants monitoring and prompt remediation.

Is CVE-2020-8218 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2020-8218 (Pulse Connect Secure Code Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-03-07. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-09-07. The required action was: Apply updates per vendor instructions. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2020-8218?

CVE-2020-8218 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2020-8218?

CVE-2020-8218 affects ivanti connect secure (1 version, e.g. 9.1); ivanti policy secure (1 version, e.g. 9.1); pulsesecure pulse policy secure. Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2020-8218 published, and has it been updated?

CVE-2020-8218 was published on July 30, 2020 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
