How do I patch CVE-2023-48365?

No patch has shipped for CVE-2023-48365 yet — track the qlik qlik sense advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2023-48365 across my infrastructure?

Inventory every qlik qlik sense 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-2023-48365 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-2023-48365?

O3 detects and blocks CVE-2023-48365 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-2023-48365 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-48365, including 1 in-the-wild exploitation 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-2023-48365?

CVE-2023-48365 has an EPSS (Exploit Prediction Scoring System) score of 24.7%, 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-2023-48365 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2023-48365 (Qlik Sense HTTP Tunneling Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2025-01-13. CISA required all US federal civilian agencies to remediate this vulnerability by 2025-02-03. The required action was: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. This CVE has been used in known ransomware campaigns. 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-2023-48365?

CVE-2023-48365 is classified as CWE-444 (CWE-444). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Which products and versions are affected by CVE-2023-48365?

CVE-2023-48365 affects qlik qlik sense (8 versions, e.g. august_2022, august_2023, february_2022…). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2023-48365 published, and has it been updated?

CVE-2023-48365 was published on November 15, 2023 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.

Description

Qlik Sense Enterprise for Windows before August 2023 Patch 2 allows unauthenticated remote code execution, aka QB-21683. Due to improper validation of HTTP headers, a remote attacker is able to elevate their privilege by tunneling HTTP requests, allowing them to execute HTTP requests on the backend server that hosts the repository application. The fixed versions are August 2023 Patch 2, May 2023 Patch 6, February 2023 Patch 10, November 2022 Patch 12, August 2022 Patch 14, May 2022 Patch 16, February 2022 Patch 15, and November 2021 Patch 17. NOTE: this issue exists because of an incomplete fix for CVE-2023-41265.
