CVE-2023-50292
Apache Solr 6.0.0 – 8.11.3
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-50292 is a high-severity Incorrect Permission Assignment for Critical Resource (CWE-732) vulnerability in Apache Solr. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 13% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-50292 is an incorrect permission assignment and improper control of dynamically-managed code resources vulnerability in Apache Solr. It affects the Schema Designer feature in versions 8.10.0 through 8.11.2 and 9.0.0 before 9.3.0. The flaw stems from the Schema Designer loading configSets without verifying their trusted status, which is normally granted only to those created by authenticated users; this oversight permits unauthenticated configSets to load external libraries.
Unauthenticated remote attackers can exploit the issue over the network without authentication or user interaction. By supplying or referencing an untrusted configSet through the Schema Designer, they can trigger external library loading that would otherwise be restricted, resulting in high-impact confidentiality exposure as reflected in the CVSS 7.5 rating.
Apache Solr security advisories direct users to upgrade to version 9.3.0 to resolve the permission check omission. The referenced OSS-Security mailing list postings and the project security page reiterate the same upgrade guidance and note the affected range.
The associated EPSS score has reached a peak of 0.4667 with a current value of 0.4645, indicating sustained moderate exploitation interest following disclosure.

Vulnerability Data
Incorrect Permission Assignment for Critical Resource, Improper Control of Dynamically-Managed Code Resources vulnerability in Apache Solr. This issue affects Apache Solr: from 8.10.0 through 8.11.2, from 9.0.0 before 9.3.0. The Schema Designer was introduced to allow users to more easily…
more
configure and test new Schemas and configSets. However, when the feature was created, the "trust" (authentication) of these configSets was not considered. External library loading is only available to configSets that are "trusted" (created by authenticated users), thus non-authenticated users are unable to perform Remote Code Execution. Since the Schema Designer loaded configSets without taking their "trust" into account, configSets that were created by unauthenticated users were allowed to load external libraries when used in the Schema Designer. Users are recommended to upgrade to version 9.3.0, which fixes the issue.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Enforces the access control policy that defines permissions on resources, thereby stopping incorrect assignments from remaining exploitable.
Directly requires assignment of only the minimum necessary permissions, preventing overly broad grants on critical resources.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.1 only requires the existence of an overarching policy and topic-specific policies (including on access control); it does not itself enforce, implement, or act on permissions and therefore cannot stop CWE-732 from being exploitable.
A.5.12 only defines and communicates a classification scheme (with owners accountable for applying it); it does not itself enforce, restrict or decide any permissions, so the CWE-732 permission flaw can still be present and exploitable.
A.5.15 directly requires determining access needs, defining and communicating an access control policy, implementing rules that map rights/restrictions to entities (including consistency with classification), and considering need-to-know, privileged restrictions, segregation, formal authorization, and dynamic factors — which squarely stops most incorrect permission assignments from being exploitable; the bounded remainder is misconfigurations that violate the policy itself.
A.5.18 directly governs the provisioning, review, adjustment and revocation of logical access rights (including for critical resources) according to business needs, policy, SoD and risk, which stops most unintended actors from reading/modifying via incorrect permissions; the bounded remainder is incorrect permission assignments that are not access-right decisions at all (e.g. filesystem umask, ACL syntax errors).
Documented responsibility for protecting assets encourages correct permission settings rather than leaving them at insecure defaults.
Monitoring supplier policy changes and conducting audits can reveal incorrect permission assignments on resources managed by the supplier, prompting corrective action before they are exploited.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
